What technical SEO can and cannot do
It can stop a page being invisible. It cannot make an unremarkable page outrank a better one.
That distinction matters commercially, because technical work is easy to sell and easy to over-buy. A site with a genuine indexation problem gets a step change from two weeks of work. A technically clean site gets a slightly faster technically clean site, and an invoice.
The audit exists to tell you which of those you are before you commit a budget.
The order the fixes go in, and why
Indexation first. A page not in the index earns nothing. Everything else is theoretical until this is resolved, and on the sites audited here it is the most common blocker by a distance.
Duplication and canonicals second. Splitting one page’s signals across three URLs weakens all three. One template mistake does this to every page on the site at once.
Redirects and internal links third. Recovering authority the site already has is cheaper than earning new authority. A migration that sent old URLs to the homepage threw that authority away, and a redirect map gets it back.
Performance fourth. Real user metrics, on mobile, on the pages that matter. Google publishes the thresholds: 2.5 seconds for Largest Contentful Paint, 200 milliseconds for Interaction to Next Paint, 0.1 for Cumulative Layout Shift, assessed at the 75th percentile of real visits over 28 days.
Structured data last. It is the least load-bearing item on the list, and the most visible in a report, which is why some audits run this list in reverse.
What you get in week one
A prioritised list. Each line says what is broken, what it is costing, and what the fix involves. If you have developers, each item is also a ticket they can action without a meeting. If you do not, the fix gets made here and verified afterwards.
Then a plain answer to the only question that matters: whether technical work is what is holding this site back. Sometimes it is not, and that gets said in week one rather than in month three.
Where the line is
A perfect Lighthouse score is not a goal. Core Web Vitals are pass or fail, measured on real users, and a page that passes at 90 is not beaten by one that passes at 99.
Schema does not move rankings. It can change how a result looks, and it costs little, so it gets done, and nothing is built on it.
And if you are about to redesign, the cheapest technical work you will ever buy is the URL inventory and redirect map made before launch. Almost every large unexplained traffic drop that has arrived here was a migration, and almost all of that damage was preventable.
Remove the reasons a page cannot rank. Then go and earn the ranking.
