What SEO actually means
Three jobs, not one, and most sites fail at a different one than they think. What changed recently, and the one thing that did not.
The term gets used as though everybody already agreed what it covers, which is how it ends up meaning both a technical speciality and a vague suspicion that somebody is gaming something. This is the plain version: what it is, why it is worth anything, and what has changed recently enough to matter.
What it is
Search engine optimisation is everything you do so that a search engine can find your page, understand what it answers, and decide it is the best thing to show somebody who asked that question. Three separate jobs, and most sites fail at a different one than they think.
The commercial reason it matters is simple arithmetic rather than enthusiasm. Advertising charges you for every visitor and stops the moment you stop paying. A social post is gone from most feeds within a day. A page that holds a search position keeps arriving visitors month after month at no additional cost, which is the only channel in marketing with that shape.
How the decision is made, roughly
Nobody outside Google knows the full list and you do not need it. Four ideas carry most of the weight.
- Relevance. Does the page answer the thing that was actually asked. A page about hiking boots does not answer a question about running shoes for beginners, however good it is.
- Quality. Does it answer completely, or does it leave the reader going somewhere else for the second half.
- Trust. Is it clear who is behind this and why they would know. Do other credible sites point at it.
- Experience of using the page. Does it load, does it work on a phone, is the answer buried under interruptions.
What has actually changed
Two things, and it is worth separating the real change from the panic around it.
First, answers now often appear above the results. Some questions are resolved without anyone visiting a site, and that is a genuine loss of traffic for pages whose entire value was a short factual answer. The pages less affected are the ones somebody still needs to read: a comparison with judgement in it, an explanation of something the reader has to do, anything where the answer is a decision rather than a fact.
Second, Google has become explicit about mass-produced content. Its spam policies name scaled content abuse, meaning many pages made primarily to rank rather than to help, and state that the test is the purpose rather than how the pages were produced. The same guidance says AI gives no ranking advantage and that inventing author profiles counts as deception. So the strategy of publishing a great deal quickly got worse, not better.
Where to start if you are starting
- Write down the question your page answers, in the words somebody would type. If you cannot, the page has no search intent and no amount of optimisation gives it one.
- Put that question in the title, plainly. A descriptive title beats a clever one, because the clever one is competing with the reader's patience as well as with other results.
- Answer it completely on the page. The commonest fixable failure is an article that covers half a question well.
- Break it into sections with headings that say what is in them, which helps a reader skim and a search engine understand the structure.
- Link your own pages to each other where it is genuinely useful, which is how both readers and crawlers find the rest of what you have written.
- Make it work on a phone and load quickly, because that is the condition most of your readers are in.
- Go back to your best pages every few months and fix what has gone out of date.
Three things it is not
- Not a trick. There is no setting that moves a page up, and anything presented as one is either out of date or about to be.
- Not fast. A new site is an unknown quantity and takes months to be treated as anything else, which is a cost of entry rather than a sign of failure.
- Not only for large companies. A single page that answers one specific question properly outranks a large site's general page on that question regularly, because relevance is not a function of size.
If this is the first thing you have read on the subject, the next useful step is the mechanics: how a page is found and indexed in the first place, and what to do when a position disappears. Those are the two articles that follow this one.
Work to do
- Write the question each of your main pages answers, in the reader's words. Any page with no answer to that is the first thing to fix.
- Check whether your titles describe the content or describe your feelings about the content.
- Pick your best page and read it as somebody who asked that question, then write down what they would still have to look up elsewhere.
