Technical SEO: the fixes that actually move rankings

Technical SEO has a reputation for being a long list of small tweaks. In practice, a handful of problems account for most of the damage, and the rest of the checklist is noise. Here is what genuinely matters, roughly in order of how often it is the actual cause.

1. Pages that cannot be indexed

The most severe and the most common. A page that search engines cannot index cannot rank, however good it is.

The usual culprits: a noindex tag left over from the staging site — which happens more often than anyone admits, sometimes across an entire launch; a robots.txt rule blocking a whole section; or a canonical tag pointing every page at the homepage.

Check first: whether your important pages are actually in the index at all. If a page is missing, nothing else on this list matters for it.

2. Several URLs for the same page

The same content reachable at more than one address splits its own signals. Common causes: with and without www, http and https, with and without a trailing slash, and parameter versions from filters and tracking links.

Fix: pick one form, redirect the rest permanently, and make every canonical tag point at the chosen version. This is dull and it is frequently the difference between a page ranking and hovering.

3. Titles and headings that describe nothing

Not a technical fix exactly, but it sits in the same audit and it is more valuable than most of them. Every page needs a unique title that says what the page is, and one clear top-level heading. Sites with twenty pages titled “Home | Company Name” are throwing away the most direct signal they have.

4. Speed, but only the parts that count

Speed matters, and it matters most on phones on poor connections. But chasing a perfect score is a poor use of time. The parts that move: how quickly the main content appears, whether the page jumps around while loading, and whether it responds when tapped. Oversized images and unnecessary scripts cause most of it. Core Web Vitals in plain English covers this properly.

5. Structure a machine can follow

Every important page should be reachable from the homepage in two or three clicks, through ordinary links. Pages that are only reachable through a search box or a filter are effectively invisible. An XML sitemap helps, but it is a hint rather than a substitute for genuine internal linking.

Internal links also tell search engines what a page is about, using the words you link with. Vague links — “click here”, “read more” — waste that.

6. Structured data, where it earns something

Marking up your organisation, breadcrumbs, articles, FAQs, products and opening hours can change how your result is displayed, which affects clicks even when position does not change. It is worth doing for those types and largely a waste of effort beyond them.

Never mark up things that are not on the page, and never mark up reviews you do not have. Both are penalised, and the second is a bigger problem than a ranking one.

7. Redirect chains and broken links

After a few years of changes, sites accumulate redirects pointing at redirects and links to pages that no longer exist. Neither is catastrophic; both are cheap to fix and worth clearing periodically.

What you can safely ignore

• Keyword density. It has not been a factor for many years.
• Meta keywords. Ignored by every major search engine.
• Chasing a perfect performance score for its own sake.
• Any tool that scores your site out of 100 and sells you the fix.

The order to work in

1. Confirm your money pages are indexed.
2. Resolve duplicate URL forms and canonicals.
3. Write real titles and headings.
4. Fix the worst speed offenders — usually images.
5. Make sure everything important is linked to from somewhere sensible.
6. Add structured data where it changes the result display.

Do those six and you will have addressed more than most audits, without the forty-page document.

This is what an SEO engagement starts with, and the stack we build on is listed under technologies. If you would like someone to check the first two on your site, book a call — those are usually a twenty-minute answer.
