The SEO Audit Checklist

The exact checklist we run through on every audit — technical, on-page and off-page — so you can spot the obvious issues yourself before you ever talk to an agency.

Technical checks

Site loads in under 2.5 seconds on mobile · robots.txt isn't blocking pages it shouldn't · XML sitemap exists and is submitted to Search Console · HTTPS is enforced sitewide · no major Core Web Vitals failures.

On-page checks

Every page has a unique title tag and meta description · one H1 per page matching search intent · images have descriptive alt text · internal links use descriptive anchor text, not "click here".

Content checks

Top pages actually answer the query a searcher typed · no thin or duplicate content across near-identical pages · content is kept current, not abandoned after publish.

Off-page checks

Google Business Profile is claimed, verified and complete (if local) · no obviously spammy or broken backlinks · NAP (name, address, phone) is consistent across directories.

FAQ

Frequently asked questions

How often should I re-run an SEO audit?

Quarterly is a sensible baseline for an active site; immediately after any redesign, migration or major content change, since those are when technical issues most often get introduced unnoticed.

Can I run this checklist on any website, including competitors'?

The technical and on-page checks, yes — most are visible in "view source" or free tools. What you can't audit externally is what's happening off-page for someone else's site, like their exact link sources.

What tools do I need to check these myself?

Google Search Console and PageSpeed Insights cover most of it for free. Our own free audit tool runs a version of this exact checklist automatically in seconds.

I passed every check but still don't rank — why?

A clean technical/on-page audit removes blockers, it doesn't guarantee rankings against genuinely stronger competition. At that point the gap is usually content depth or backlink authority, not the checklist items.

What's the single most commonly failed check?

In our experience running this on real sites: missing or duplicate meta descriptions, and images without alt text — both easy to fix, both very commonly ignored.

Does page speed really need to be under 2.5 seconds?

That figure tracks with Google's "good" threshold for Largest Contentful Paint, one of the Core Web Vitals. Slower doesn't mean instant penalty, but it does correlate with worse rankings and worse conversion.

What counts as "thin content"?

A page that doesn't say enough to be genuinely useful for its target search — often under 200-300 words with no real substance, or a template page with the town name swapped and nothing else changed.

Should every page have a meta description?

Yes — if you don't write one, Google generates its own snippet from the page content, which is rarely as compelling or accurate as one you've written deliberately.

Is HTTPS really still worth checking in 2026?

Almost every site has it by now, but it's still worth confirming it's enforced sitewide (no mixed content warnings, no HTTP pages still accessible) rather than just present on the homepage.

What if my sitemap exists but isn't submitted to Search Console?

Google can still find it via robots.txt or by crawling, but submitting it directly speeds up discovery of new or changed pages — a five-minute task worth doing.
