The importance of SEO, and when it is not important at all

Why is SEO important? The short answer

SEO is important because search is how most people find a business they do not already know, and because an organic position keeps producing enquiries after you stop paying for it.A paid click costs the same on day one and day one thousand. A ranking, once earned, does not. For a local business the effect is sharper still: the three map pack results take the majority of local clicks, so the gap between third and fourth is worth more than the gap between fifth and fifteenth anywhere else.

Search optimisation is the work of being the business a search engine names when someone is looking for what you sell. That is it. Everything else (the keyword research, the technical audits, the content plans) is method, not purpose.

What SEO is actually worth, in numbers

"Important" is not a number, so here is how to turn it into one for your own business. You need three figures, and you already have all of them:

• What one customer is worth: not the first invoice, the lifetime value. A cleaner at £40 a visit who stays two years is a £2,000 customer, not a £40 one.
• What you currently pay per enquiry: from ads, directories, or lead-generation sites, whichever you use.
• How many enquiries you would need to cover a campaign. At £497 a month, a trade with a £2,000 average job needs roughly one extra job a quarter.

Do that arithmetic before you take a single sales call. It turns a vague argument about importance into a five-minute decision, and it is the sum an agency will rarely do for you, because it sometimes produces the answer "no".

The importance of SEO compared with the alternatives

SEO is not the only way to be found, so here is the honest comparison rather than the sales pitch.

Against paid search: ads produce enquiries this week and stop the day the card declines. SEO produces nothing for three months and then compounds. Cost per enquiry usually crosses over somewhere between month nine and month eighteen, after which organic is substantially cheaper. Running both is better than either, becausethree months of ad data tells you which terms actually convert, which is where the organic work should then aim.

Against social media: different intent entirely. Social reaches people who were not looking for you; search reaches people who were. For a business selling a considered purchase, the second is worth far more per head. And unlike a follower count, a ranking is not subject to somebody else changing an algorithm you have no relationship with.

Against directories and lead-generation sites: these charge per lead and sell the same lead to your competitors. They work, and they never stop costing. The longer-term problem is that you are renting a position on somebody else's asset rather than building your own.

What has changed, and why the answer is different from 2019

Every article written on this subject before 2024 needs one update: the click is no longer guaranteed. AI overviews and assistants increasingly answer the question on the results page without sending anyone anywhere. Two things follow from that.

First, ranking for informational questions is worth less than it was. A page that explains what a heat pump is will get summarised, not visited. Second, and this is the part people miss, ranking for commercial intent is worth more, because those searches still end in a click. Nobody books a plumber from a summary.

In practice: put your effort where someone is trying to buy, not where they are trying to learn. We have seen this on our own site: an article of ours collects nearly 108,000 impressions and no clicks, because it answers a question rather than serving a customer.

Does SEO still matter with AI search?

This is now the most common version of the question. The short answer is yes: it matters more, not less, but differently.

There is no separate AI index to be inserted into. When somebody asks ChatGPT, Claude or Perplexity to recommend a business, the system typically runs an ordinary web search, reads a handful of results and composes an answer from what it can extract and verify. Being in those results is the prerequisite for being cited. If you are on page four, you are not in the sample being read, and no amount of AI-specific work compensates for that.

What changes is the emphasis. Clarity and structure now matter more than keyword placement, because the thing reading your page is pulling out facts rather than counting terms. Self-contained answers, consistent details across your website and your Google Business Profile, and structured data are what make a business citable,which we cover properly here, andthe do-it-yourself version is here.

What SEO is actually made of

Being findable

The technical layer: a site that loads quickly, works on a phone, and can be crawled without tripping over itself. This is table stakes, and usually the cheapest thing to fix: most sites we audit have two or three problems here that take a day to resolve.

Being relevant

Content that matches what people actually type, on pages that each have one job. The most common failure we see is the opposite: dozens of near-identical pages competing with each other, which is worse than having one good one.

Being credible

Other sites referencing you, reviews accumulating, a consistent set of facts about your business everywhere it appears. This is the slowest part and the hardest to fake, which is exactly why it counts for so much.

When SEO is the wrong spend

Four situations where we would tell you not to bother, or not yet:

• You need enquiries this month. SEO cannot do that. Paid search can. Taking your money for a campaign that cannot meet your deadline would be dishonest.
• Your site cannot convert. Sending more people to a page nobody enquires through is an expensive way to prove the page is the problem.
• Your customers do not search. Some businesses genuinely run on referral and relationship. Ranking them changes very little.
• Your margins will not carry it. If a customer is worth £40 and the campaign costs £497 a month, the arithmetic has to work over a lifetime value you can actually evidence.

How to tell whether it is working

Not by clicks, at least not at first. Click counts on a small site are too noisy to read week to week. Watch average position on the terms that matter commercially, and watch the count of queries where you rank in the top three. That second number is the one that turns into revenue, and it is the one we report on.

If you want to see what that reporting looks like on a real account, ourcase studies have the figures, and ourprices are published rather than quoted on request.

How important is SEO for a small business specifically?

More important than for a large one, and for a reason that is not obvious: a small business cannot outspend anybody, but it can out-specify them. A national competitor will not build a page about your town, will not answer the question your customers actually ask, and will not write about the specific job you did on a street somebody recognises.

That is the whole strategy for most small businesses. Not competing for "plumber", but competing for "boiler repair Hillsborough", "emergency plumber Bessacarr", and the forty other searches that are individually small and collectively the entire market. It is also whylocal SEO is usually where we start: the map pack moves in weeks rather than months, and for a business with one location it is frequently worth more than the whole first page beneath it.
