What is SEO?

SEO, or search engine optimisation, is the process of improving your website and wider online presence so your business can be discovered when people search for relevant information, products or services. It combines technical optimisation, content, authority, user experience and an understanding of search intent to increase organic visibility and, ultimately, contribute to meaningful business outcomes.

Why is SEO important?

SEO is important because it connects your business with people who are actively searching for information, solutions, products or services related to what you offer. Done well, SEO can increase relevant visibility, attract potential customers, build authority and generate enquiries or sales. In 2026, that visibility extends beyond traditional rankings into AI-powered and conversational search experiences.

How does SEO work?

Search engines discover and process content from across the web and use a wide range of systems to determine what may be useful and relevant to a person’s search.

SEO helps make sure your business is eligible, relevant and useful when those searches happen.

In practice, that means considering several interconnected areas:

• Technical SEO: Can search engines efficiently access, crawl and understand your website?
• Content and on-page SEO: Do your pages genuinely answer what your audience is looking for?
• Search intent: Do you understand why someone is searching, rather than simply which words they’re typing?
• Authority: Are there reasons for users and search engines to trust your business and its expertise?
• User experience: Once someone finds you, can they easily understand your offer and take the next step?
• Measurement: Can you identify which organic activity is contributing to enquiries, sales and other business objectives?

The last point is sometimes forgotten. SEO without appropriate measurement makes it much harder to distinguish activity from actual performance.

Does SEO still revolve around Keywords?

Keywords still matter. But they shouldn’t be the sole focus of an SEO strategy.

After more than a decade working in digital marketing, one of the biggest changes I’ve seen is the shift from obsessing over individual keyword positions towards understanding context, intent and topics.

Years ago, SEO conversations could revolve heavily around:

“Are we number one for this keyword?”

Today, that’s only one piece of information.

We still use keyword research to understand demand, customer language and search behaviour. But search engines have become considerably better at understanding the context around a search and the different ways someone might ask essentially the same question.

Google itself advises website owners that they don’t need to anticipate every possible variation of a search because its language matching systems can understand relationships between pages and queries.

This becomes even more important as people use conversational and AI-powered search experiences.

So rather than only asking:

“Where do we rank for this keyword?”

I’d ask:

Are we visible for the subjects that commercially matter to the business? Are we answering the questions customers genuinely have? Are we appearing at different stages of their research? And is that visibility contributing to meaningful business outcomes?

Rankings still help us answer part of that.

They just don’t tell us the whole story.

What are the main areas of SEO?

SEO covers several interconnected disciplines. You don’t necessarily need a separate strategy for every one of them; the important thing is understanding which areas are preventing or creating growth for your business.

Technical SEO

Technical SEO ensures search engines can access, crawl and understand the important parts of your website.

That might involve indexing, site architecture, redirects, internal linking, page performance, mobile usability or resolving technical problems.

But fixing technical issues isn’t a business outcome in itself.

A website audit could identify hundreds of issues. That doesn’t mean fixing all 100 is equally important.

The real skill is identifying which technical improvements could meaningfully affect search visibility or user experience and prioritising accordingly.

Content and on-page SEO

Content SEO isn’t simply publishing blogs.

For one business, the biggest opportunity might be creating a comprehensive service page. For another, it could be improving product information, publishing original research, demonstrating expertise through case studies or answering questions its sales team hears every week.

The question shouldn’t be:

“How many blogs should we publish this month?”

It should be:

“What does our audience need to know that we’re currently failing to answer?”

That shift produces better content for customers and a much stronger foundation for organic search.

Authority and off-page SEO

SEO also happens beyond your website.

Relevant backlinks, digital PR, independent mentions, reviews, citations and wider brand recognition can all help strengthen your digital presence.

Again, quality and context matter.

One genuinely relevant mention from a respected publication within your industry can be considerably more valuable than accumulating large numbers of irrelevant links simply because a tool gives them a particular score.

Local SEO

For businesses serving particular geographic areas, local SEO helps increase visibility when people search for products or services within those locations.

That can involve optimising the website alongside Google Business Profile, reviews, local landing pages, business information and Maps visibility.

What about AEO and GEO?

AEO, or Answer Engine Optimisation, and GEO, or Generative Engine Optimisation, have become increasingly common terms as AI changes how people search.

Broadly, they describe improving the likelihood that a business, brand or piece of content can be understood and surfaced within answer-based and generative search experiences.

But I don’t believe businesses should see these as replacements for SEO.

Google’s own guidance is unusually clear on this: established SEO best practices continue to apply to its AI experiences, and there are no special additional technical requirements or AI-specific schema needed to appear in AI Overviews or AI Mode.

SEO hasn’t been replaced. Search has expanded.

And our strategies need to expand with it.

What are the benefits of SEO?

The benefits of SEO become much clearer when we stop treating a ranking as the final objective.

Ranking higher can be valuable.

Generating more organic traffic can be valuable.

But neither automatically means the business is performing better.

1. SEO helps your business capture existing demand

One of SEO’s greatest strengths is intent.

Someone searching for a service, researching a problem or comparing providers is already demonstrating some level of interest.

SEO gives your business the opportunity to become part of that research process.

And not every valuable search is immediately transactional.

Someone might begin with:

“Why is my website not appearing on Google?”

They may later search:

“How does SEO improve website visibility?”

and eventually:

“SEO agency for B2B businesses”

Those searches represent different stages of the same potential buying journey.

The first is problem-led. The second is solution-led. The third demonstrates much stronger commercial intent.

A strong SEO strategy considers that entire journey rather than focusing solely on the final high-intent keyword.

That means creating genuinely useful content for someone who is still understanding their problem while ensuring your commercial pages are visible when they are ready to compare providers or make an enquiry.

2. SEO can generate qualified enquiries and sales

Traffic is useful.

But traffic alone is not a business objective!

We’ve seen this first-hand with one of our clients.

The business wasn’t investing in SEO/AEO during 2025. When we began working with them in 2026, one of the first things we implemented was more robust conversion tracking.

Why?

Because without accurate measurement, we couldn’t confidently determine what organic visitors were actually doing after reaching the website.

Good SEO requires good data.

Tracking helps us understand which pages, search journeys and channels are contributing to meaningful actions. That information allows us to decide where to invest, what to optimise and where opportunities may be being missed.

Alongside improving measurement, we implemented an organic search strategy focused on increasing relevant visibility and connecting SEO activity more closely with commercial intent.

Between January and August 2026, the website recorded 135 contact enquiries attributed to organic search.

But here’s the interesting part.

During the same period, organic sessions were 28% lower year on year.

If we’d looked only at the traffic graph, we could easily have concluded that organic performance had declined.

The conversion data told us something very different.

The website was generating meaningful enquiries from organic search despite receiving fewer organic sessions.

Because equivalent conversion tracking wasn’t available during the previous period, we can’t responsibly claim a year-on-year percentage increase in enquiries. In itself, that demonstrates why establishing accurate measurement is so important.

But the 2026 data does demonstrate something I’ve become increasingly passionate about:

More SEO traffic doesn’t automatically mean better SEO performance.

I’d rather see 5,000 relevant visitors who include potential customers than 50,000 visitors who have little or no commercial relevance to the business.

That’s why SEO measurement needs to go beyond sessions.

3. SEO can build visibility throughout the customer journey

People don’t only search when they’re ready to buy.

They search when they have a problem.

They search when they’re learning.

They search when they’re comparing different solutions.

They search when they’re building a business case.

And they search again when they’re deciding which company they trust enough to contact.

That creates opportunities for SEO throughout the customer journey.

This is particularly important for B2B organisations and higher-consideration purchases where the journey between initial discovery and eventual enquiry may involve multiple searches, websites and marketing channels.

A business that only optimises for the final “buy now” moment can miss much of the research happening before it.

4. SEO can create long-term visibility

SEO and PPC work differently.

With PPC, visibility is closely connected to media spend. Stop paying for advertising and the paid visibility stops.

SEO can create digital assets that continue delivering value.

A genuinely useful service page, guide, comparison, case study or piece of research could continue attracting relevant search visibility long after it was originally created.

That doesn’t mean SEO is free or passive.

Competitors change. Websites change. Customers change. Search behaviour changes.

Content needs updating and websites need maintaining.

But the work undertaken through SEO can build upon itself through stronger pages, greater authority, broader topical coverage and an increasingly useful website.

That’s where SEO’s long-term value becomes particularly interesting.

5. SEO can build authority, not just rankings

One of the biggest opportunities in modern SEO is creating information that demonstrates why someone should trust your business.

That could include:

• First-hand expertise
• Original research and data
• Detailed case studies
• Expert commentary
• Customer questions
• Transparent processes
• Genuine comparisons
• Detailed product or service knowledge

This matters even more in a world where producing generic content has become incredibly easy.

Generic information can be reproduced. First-hand experience can’t.

Hundreds of websites can explain what SEO means.

Only we can explain what we’ve learned from delivering SEO campaigns across real businesses for more than a decade.

The same principle applies to our clients.

Their engineers, advisers, consultants, technicians, sales teams and specialists possess knowledge that doesn’t exist within a keyword research tool.

Getting that expertise onto the website can create something genuinely useful.

6. SEO can help you understand your customers

Search data isn’t only SEO data.

It’s customer insight.

The things people search for can tell you:

• Which problems they’re experiencing
• What they don’t understand
• Which products or services they’re comparing
• The language they actually use
• Which objections they have
• How demand is changing
• What matters at different stages of their buying journey

Those insights shouldn’t remain inside the SEO department.

We’ve used search insight to influence website architecture, PPC campaigns, service positioning, content strategy, conversion journeys and wider digital marketing decisions.

And that brings me to what I think is one of the most important points about SEO.

SEO shouldn’t work in isolation

One of the most persistent misconceptions I still hear is:

“SEO equals leads.”

SEO absolutely can generate leads.

But that statement oversimplifies how people actually buy.

Imagine someone discovers your business after asking Google a question.

A week later they see one of your LinkedIn posts.

Then they search your brand.

They read a case study.

Two weeks later they click a PPC ad.

Eventually they return directly and submit an enquiry.

Which channel generated that lead?

Your analytics platform may attribute the conversion to one particular source.

The real customer journey involved several.

That’s why I don’t believe SEO should sit in a silo.

SEO, PPC, content, websites, CRO, analytics, social and brand activity can all influence each other.

The objective isn’t to make one channel look good. It’s to make the marketing strategy work.

What does successful SEO actually look like?

There isn’t one universal definition of SEO success.

That’s because different businesses need different outcomes.

For one client, success may mean increasing local enquiries.

For another, it may mean entering a completely new market.

For another, it could mean increasing visibility for a particular profitable service rather than increasing overall website traffic.

Our own client data demonstrates just how differently SEO success can look.

Example 1: Lower traffic, but 135 organic enquiries

The anonymous client example above recorded 135 contact enquiries from organic search between January and August 2026 despite organic sessions being 28% lower year on year.

That’s a good example of why traffic needs context.

The objective isn’t simply to attract as many people as possible.

It’s to attract the right people and help them take the next step.

Example 2: Growing visibility, traffic and conversions together

For another client, sustained organic optimisation resulted in:

• Ranking search queries increasing from approximately 820 to 1,785
• Top 10 visibility increasing from 217 to 917 queries
• Average ranking position improving from 24.5 to 9.9
• Organic sessions increasing by 42.4%
• 655 conversions recorded during the reporting period

This example tells a different story.

Here, greater relevant search visibility translated into increased organic discovery and greater opportunity to convert.

The important thing is the progression:

Visibility → relevant traffic → action.

Rankings played an important role.

But they weren’t the finish line.

Example 3: SEO and PPC working together

Gigasure is one client we can talk about publicly.

When the business entered the highly competitive travel insurance market, we didn’t approach SEO and PPC as competing channels.

We developed them as part of a wider digital strategy.

Within 12 months, Gigasure achieved more than 1,400 ranking UK keywords, 300+ SERP features and a 17x increase in monthly sales. The strategy combined organic search with paid media rather than asking one channel to do everything.

For me, that’s an important SEO lesson.

Strategy first. Channels second.

What more than 10 years in digital marketing has taught me sbout SEO

As a Chartered Marketer with more than 10 years’ experience in digital marketing, one thing has become particularly clear:

The strongest SEO campaigns happen when you properly understand the business behind the website.

The best client relationships we’ve had aren’t the ones where somebody gives us a spreadsheet of keywords and tells us to “do the SEO”.

They’re the ones where we’re allowed to become an extension of the marketing team.

We want to know:

• What actually makes the business money?
• Which services are most profitable?
• What does the business want to grow?
• What does a good lead actually look like?
• What questions does the sales team hear every week?
• Why do customers choose the business?
• Why do prospects sometimes choose competitors?
• What objections prevent people from buying?
• Where does the business have capacity?
• What makes its expertise genuinely different?

Because those answers affect what we optimise.

Without them, an SEO agency could successfully increase traffic while making very little difference to the actual business.

Partnership makes better SEO

SEO specialists understand search.

Clients understand their businesses.

The best results tend to happen when those two areas of expertise come together.

When clients allow us to properly get underneath the business, share sales insights and involve us in wider commercial conversations, we can build strategies around what customers genuinely need rather than simply what an SEO tool says has the highest search volume.

And the information should flow both ways.

If PPC identifies unexpected demand for a service, SEO can investigate the longer-term organic opportunity.

If the sales team hears the same question repeatedly, that might indicate an information gap we can address through content.

If organic search reveals new customer concerns, those insights could influence the website, PPC messaging and even the sales process.

That’s when SEO stops being a standalone activity and starts becoming part of marketing strategy.

Should I invest in SEO or PPC?

If someone asks me whether they should invest in SEO or PPC, my answer is usually:

Potentially both.

I don’t believe there’s a universal winner in SEO vs PPC.

It depends on the business, the market and, importantly, the context of the search.

We need to understand:

• What is someone actually looking for?
• Where are they in the buying journey?
• How competitive is the search?
• How quickly does the business need visibility?
• What is acquiring a customer worth?
• Where does the business already have organic visibility?
• Where could paid search fill a gap?

PPC may make sense for a high-intent service where immediate visibility is important.

SEO may build sustainable visibility around that service and related topics over time.

Organic content might capture someone earlier in their research journey while paid search targets customers who are closer to making a decision.

Neither automatically wins.

Start with the customer and commercial objective. Then decide which channels should do the job.

How long does SEO take to work?

There is no universal SEO timeframe.

And I’d be cautious of anyone who promises one.

Some technical changes can produce relatively quick improvements.

Building strong visibility within a highly competitive market can take considerably longer.

The timeframe depends on factors such as:

• Existing website authority
• Competitiveness
• Technical condition
• Current content
• Competitor strength
• Geographic targeting
• Previous SEO activity
• Available resources
• How quickly recommendations can actually be implemented

For most businesses, I’d encourage thinking about SEO in terms of months and years rather than days and weeks.

You establish the foundations.

You understand the audience.

You improve existing pages.

You create useful new resources.

You build authority.

You measure.

You learn.

You improve again.

That’s why I see SEO as an investment rather than a quick campaign.

How do you measure whether SEO is working?

This is where I think SEO needs to become much more commercially minded.

There shouldn’t be one universal SEO KPI.

What we measure should depend on what the business is trying to achieve.

That could include:

Commercial outcomes: qualified enquiries, sales, revenue, appointments and pipeline.

Conversions: contact forms, phone calls, downloads, demo requests or other meaningful actions.

Search visibility: impressions, rankings, Top 3/Top 10 presence and visibility around commercially important topics.

Organic traffic: particularly traffic reaching strategically important areas of the website.

Local performance: Maps visibility, Google Business Profile engagement and local enquiries.

Brand discovery: how often people actively search for the business or encounter it during their research.

AI search visibility: appearances, citations, referral traffic and other measurable visibility within AI-powered search experiences.

But none of those metrics should automatically be viewed in isolation.

Even conversion numbers without understanding lead quality can be misleading.

Good measurement connects search activity back to the objectives of the business.

Is SEO still important in an AI search world?

Yes.

But how we think about search visibility needs to evolve.

Google reported in 2026 that AI Overviews had reached more than 2.5 billion monthly active users, while AI Mode had surpassed one billion monthly users.

That doesn’t mean people have stopped searching.

It means the interface and behaviour around searching are changing.

Someone can now ask longer questions, explore follow-up queries and receive generated answers alongside or instead of traditional search results.

So I don’t think the right response is:

“SEO is dead. We need GEO instead.”

I think it’s:

“Search has changed. Our SEO strategy needs to change with it.”

We need to think about whether a business is understandable, authoritative and useful across a wider search ecosystem.

That includes traditional organic listings.

But increasingly it also means AI Overviews, AI-powered search experiences and other generative platforms.

The terminology will probably continue changing.

The principle underneath it is much more stable:

Understand what your audience needs and become a genuinely useful, credible source around it.

Is SEO a one-off activity?

Usually, no.

There are SEO projects that can be completed as standalone pieces of work, such as migrations, technical audits or specific optimisation projects.

But businesses competing for ongoing search visibility generally benefit from continuous investment.

Customers change.

Competitors change.

Services change.

Websites change.

Search behaviour changes.

And search technology changes.

SEO therefore becomes an ongoing cycle:

Research → optimise → measure → learn → improve.

Businesses that treat SEO as part of their long-term marketing infrastructure tend to have far more opportunity to learn from the data and build upon previous work than those that switch it on for a few months whenever traffic falls.

Does every business need SEO?

Not necessarily to the same extent.

And this is where strategy has to come before selling a channel.

If very few people search for your type of product, heavily investing in traditional SEO may not be the immediate priority.

If almost every potential customer researches your service through Google before contacting a supplier, search visibility could be critical.

Some businesses need local SEO.

Others need national thought leadership.

Some need e-commerce optimisation.

Some primarily need technical improvements and stronger commercial landing pages.

Others would benefit from answering hundreds of specialist questions their customers are already asking.

The answer should depend on how your customers behave and what your business needs to achieve — not simply because an agency sells SEO.

Frequently Asked Questions About SEO

Can SEO guarantee a number-one Google ranking?

No.

No SEO agency controls Google’s search results, and rankings are affected by relevance, competition, search context and Google’s systems.

A good SEO strategy should aim to increase meaningful organic visibility rather than guarantee a particular position.

Do I need to publish blogs for SEO?

No.

Blogs can be valuable when they answer genuine customer questions, but publishing blogs isn’t the same as doing SEO.

For some businesses, improving service pages, product information, case studies, internal linking or technical performance will create considerably more value than committing to an arbitrary number of monthly articles.

The question shouldn’t be “How many blogs do we need?”

It should be “What information does our audience need?”

Does AI-generated content hurt SEO?

Using AI doesn’t automatically mean content won’t perform.

The important question is whether the finished content is accurate, useful, original and genuinely adds value.

AI can be a useful part of the content process.

But publishing hundreds of generic articles because it’s now cheap and easy to produce them doesn’t create expertise.

First-hand experience, original insight and genuine subject knowledge are still what make content worth consuming.

Is SEO free?

Organic search doesn’t charge for each click in the same way as PPC.

But good SEO isn’t free.

It requires investment in areas such as expertise, strategy, content, technical improvements, website development, authority building, analytics and ongoing optimisation.

Can small businesses compete with larger companies through SEO?

Absolutely, where the strategy and opportunity are right.

A smaller business may not realistically compete with a national brand across every broad search.

But it could become significantly more relevant around a specialist service, particular location, industry or customer problem.

You don’t necessarily need to be the biggest business online. You need to be relevant to the people you’re trying to reach.

So, why does SEO matter going into 2027?

Because people still search.

What’s changing is how, where and why they do it.

The modern customer journey can move between Google, Maps, AI-generated answers, websites, paid advertising, reviews, social media and multiple research sessions before someone ever becomes a lead.

That means successful SEO shouldn’t be reduced to:

“Let’s rank number one for this keyword.”

The better objective is:

Understand what your customers need, create the best possible digital experience around those needs and make your business visible wherever relevant search journeys take place.

Then measure whether that visibility is contributing towards something meaningful.

Qualified enquiries.

Revenue.

Market share.

Brand awareness.

Sustainable business growth.

That’s ultimately how I believe SEO should be judged.
