What's search engine optimisation?

Search engine optimisation is the work of making a website easier for search engines to find, understand and recommend, so that when someone searches for what you sell, you’re among the options they’re shown.

That’s the whole idea. Everything else is detail, and there’s a great deal of detail, much of which exists to be sold to you.

Organic results versus paid results

Every results page contains two fundamentally different kinds of listing, and knowing which is which changes how you read the page.

Paid results are advertisements. They carry a “Sponsored” label and they appear because someone bid on that search. Stop paying and they disappear the same day. You can be at the top of the paid results tomorrow morning if your budget allows.

Organic results are earned. Nobody can buy them. They appear because a search engine has judged that page to be a genuinely good answer, based on the content itself, how the site is built, and what the rest of the web says about it. They take months to influence and they keep working after you stop paying attention.

SEO is the work of influencing the second kind.

What has actually changed lately

If you last read about SEO a few years ago, one thing has changed enough to matter.

Search engines increasingly answer the question directly on the results page, using AI-generated summaries drawn from multiple sources, rather than simply listing ten links. For a lot of purely informational searches, the user gets an answer and never clicks anything.

This has genuine consequences:

Informational traffic is worth less than it was. If your strategy was to publish articles answering general questions and hope some readers eventually become customers, that funnel has narrowed.

Commercial searches are largely unaffected. Nobody hires a plumber, chooses a supplier or books a service from a paragraph of AI-generated text. Searches with buying intent still produce clicks, and those were always the valuable ones.

Being the source now matters as much as being the link. AI summaries cite where their information came from. Being the page a summary quotes puts your name in front of someone even when they don’t click, and the pages that get cited are the clear, well-structured, obviously credible ones. Which is what good SEO produced anyway.

The practical upshot isn’t that SEO stopped working. It’s that thin content produced to fill a calendar stopped working, faster and more completely than before.

What search engines are actually assessing

Broadly, three things.

Can we read it? Can the crawler reach every page, render it, and understand the structure? A site with broken navigation, blocked resources or pages buried six clicks deep makes this harder than it needs to be.

Is it a good answer? Does the page genuinely address what the searcher wanted? Is it accurate, specific, and written by someone who evidently knows the subject? Google talks about this as experience, expertise, authoritativeness and trustworthiness, and while that framework is fuzzy, the intent behind it isn’t.

Does anyone else think so? Links from other credible sites, mentions, reviews and general reputation. This is the hardest to influence honestly and the easiest to ruin dishonestly.

Why bother

Because of when it reaches people. An ad interrupts someone doing something else. A search result meets someone who has just decided they want what you sell and is actively looking for it. That’s a fundamentally better moment to appear.

And because it accumulates. Advertising stops the day the budget does. A page that earns its position keeps earning while you sleep, and it gets cheaper per enquiry every year it stays there.

What it won’t do

SEO won’t rescue a business with no differentiator. If a visitor lands on your site and can’t tell within a few seconds why you rather than the other five results, ranking better just means more people leaving.

It won’t work in a month. Anyone promising that is either targeting terms nobody searches or doing something that will eventually get you penalised.

And it won’t fix a website that fails to convert. Doubling traffic to a page that converts nobody produces exactly twice nothing.

Where to start

Find out what’s currently true before deciding what to change. A proper analysis will tell you what’s broken, what’s already working, what your prospects are actually searching for, and where the fastest gains are. It’s unglamorous, and it prevents most of the money that gets wasted in this industry.
