75-Point Website SEO Audit Checklist: Technical, On-Page, Content, Off-Page
An SEO audit is how you find the invisible problems holding a site back: the crawl traps, the duplicate titles, the thin pages, the toxic links. Most site owners never audit at all — they publish, wait, and wonder why traffic flatlines. This 75-point checklist changes that. It walks you through every layer of a professional audit, from server-level technical issues to off-page authority, in a logical order that surfaces the highest-impact fixes first. Agencies charge hundreds of dollars for audits built on checklists exactly like this one. Here it is, free, as a checkable template you can reuse on every site you touch.
What’s inside this pack
The checklist is organized into five sections that mirror how search engines actually evaluate your site. Technical SEO (20 checks) covers crawling, indexing, speed, and site architecture — the foundation everything else rests on. On-page SEO (20 checks) covers titles, headings, meta descriptions, images, and internal linking on individual pages. Content (15 checks) evaluates depth, freshness, duplication, and search-intent match across your library. Off-page (10 checks) covers your backlink profile, anchor text, and brand mentions. Local and mobile (10 checks) covers Google Business Profile, local citations, and the mobile experience that now drives most searches. Each check is written as a concrete pass-or-fail action, so there is no ambiguity about what to verify or fix.
The 75-point SEO audit checklist (free sample)
These ten sample checks show the style of the full template — each one is a specific, verifiable action rather than vague advice. The complete 75-point checklist, formatted as a checkable list you can tick off as you work, is in the free download below.
- Confirm every important page returns a 200 status code and that no key page is accidentally blocked by robots.txt or a noindex tag — verify in Search Console's page indexing report.
- Check that the XML sitemap lists only canonical, indexable URLs under 50,000 entries, is submitted in Search Console, and returns no errors.
- Test Core Web Vitals on your top 10 traffic pages: Largest Contentful Paint under 2.5 seconds, Interaction to Next Paint under 200 milliseconds, and Cumulative Layout Shift under 0.1.
- Verify each page has exactly one H1 that includes the primary keyword naturally, with H2s and H3s forming a logical hierarchy and no skipped levels.
- Audit title tags site-wide: unique on every page, 50 to 60 characters, primary keyword near the front, and no keyword stuffing or duplication.
- Confirm every image has descriptive alt text, is compressed to a modern format, and includes width and height attributes to prevent layout shift.
- Identify thin content: flag every indexed page under 300 words and decide to expand, merge, noindex, or delete each one.
- Check for keyword cannibalization: find pages competing for the same primary keyword in Search Console and consolidate them into one stronger page.
- Review your backlink profile for spammy or irrelevant links, disavow the clearly toxic ones, and confirm your most-linked pages are the ones you want ranking.
- Test the full mobile experience on a real phone: tap targets at least 48 pixels, no horizontal scrolling, readable font sizes, and no intrusive interstitials.
How to use this pack
- Download the full checklist and work top to bottom — technical first, because on-page fixes cannot outrank crawl problems.
- Mark each check as pass, fail, or not applicable, and note the affected URLs for every failure.
- Score each failure by impact and effort, then fix the high-impact, low-effort items first for the fastest ranking wins.
- Re-run the failed checks after fixing to confirm the issue is truly resolved, not just patched.
- Save the completed audit with its date — comparing quarterly audits is how you prove progress and catch regressions early.
One disciplined pass through all 75 checks typically surfaces a short list of fixes that move the needle within weeks. The real power of the template is repetition: run it on a schedule and small problems never grow into traffic collapses.
Frequently asked questions
How long does a 75-point audit take? For a small site under 50 pages, about half a day with free tools. Larger sites take longer mostly because of crawl time, but the checklist keeps you focused so you spend time fixing rather than wondering what to check next.
What should I fix first after an audit? Indexing and crawling issues first, then page speed, then on-page basics like titles and headings. Content and link problems matter enormously but take longer to fix, so clear the technical blockers before investing there.
