Every check our audit runs, explained in plain English — what it is, why it affects your rankings, and exactly how to fix it. Organised by category so you can go straight to what's hurting your site.
There are over 160 individual checks, but they fall into a handful of categories. Work through them in priority order: fix what stops a page from being crawled or indexed first, then optimise everything else.
SEO problems are easiest to solve when you understand why each one matters rather than just chasing a list of red flags. This guide explains the reasoning behind every category of check, so a fix is something you understand instead of something you copy. Each hub below links to deep explainers for the specific issues within it.
Start at the top — crawlability and indexability are the foundation everything else sits on.
Can search engines even reach your pages? Covers robots.txt, crawl budget, and the directives that decide what gets discovered. If a page can't be crawled, nothing else matters.
Is the page allowed into Google's index, and which URL is the master copy? Covers noindex, canonical tags, and the canonical mistakes that quietly deindex whole sections.
Broken links, orphan pages, anchor text, and how authority flows through your site. The link graph decides which of your pages search engines treat as important.
Redirect chains, loops, and 301 vs 302. Done wrong, redirects leak the link equity you spent years earning.
Your XML sitemap is a direct instruction to crawlers. It should contain only canonical, indexable, 200-status URLs — and nothing else.
Titles, meta descriptions, headings, duplicate content, and thin pages — the on-page signals that affect both ranking and click-through.
LCP, CLS, and INP. Speed is a ranking factor and the first thing a user feels. Slow templates cost you rankings and conversions at the same time.
If you serve multiple languages or regions, hreflang is the most error-prone area in SEO. Covers return tags, self-references, and valid language codes.
Prefer a single actionable list? The checklist pages pull the highest-impact checks together: the 20-point technical audit, and the SEO mistakes that most often kill rankings.
This guide explains every check. The audit finds which ones your site is failing, on which pages, and tracks them over time so you can see the fixes working. Free to start, no subscription.
