Most SEO audits are either too shallow to be useful or too long to ever finish.

A 200-point audit template looks thorough but takes a week and buries the two issues that actually matter under 198 that don't.

This walkthrough is the opposite. It's the triage I run at the start of every Goldie Agency engagement — ordered by impact, doable in an afternoon, using mostly free tools. Work through it top to bottom and stop when you hit diminishing returns.

What you need (all free)

That's it. You don't need a paid audit tool to find the issues that matter.

Phase 1 — Indexation (the silent killer)

Start here, because this is where the biggest hidden problems live.

Check 1 — Is your important content indexed?

In Search Console, open the Pages report. Look at "Not indexed" pages. If your money pages are sitting in there, nothing else matters — fix this first. Unindexed pages can't rank, period.

Check 2 — Is junk getting indexed?

The reverse problem. Run site:yourdomain.com and skim. Are tag pages, filtered URLs, staging pages, or thin content getting indexed and diluting your site? Noindex or consolidate them.

Check 3 — Accidental blocks.

Check robots.txt and meta robots on your templates. I've seen six-figure sites accidentally noindex their entire blog after a redesign. Verify nothing important is blocked.

Indexation problems are invisible unless you look — and they're the most common reason "good" sites don't rank.

Phase 2 — Architecture & internal links

Check 4 — Crawl depth.

In your crawler, look at how many clicks from the homepage it takes to reach key pages. Anything beyond 3-4 clicks gets crawled rarely and ranks poorly. Flatten it.

Check 5 — Internal links to money pages.

This is the highest-leverage fix most people miss. Pull internal link counts per page. Your highest-value commercial pages should have the most internal links. Most sites do the opposite — they pour links into the blog and orphan the pages that convert.

Check 6 — Orphan pages.

Any important page with zero internal links is invisible to both users and crawlers. Link to it.

Phase 3 — Technical health

Check 7 — Core Web Vitals. Search Console's Core Web Vitals report. Fix the "poor" URLs first. Don't chase perfect scores.

Check 8 — Mobile usability. Test real pages on a real phone. Google indexes mobile-first.

Check 9 — HTTPS & redirect chains. No mixed content. Collapse redirect chains to single 301s.

Check 10 — XML sitemap. Should contain only canonical, indexable, 200-status URLs. Clean out redirects, 404s, and noindex pages.

Phase 4 — On-page

Check 11 — Title tags. Unique, under 60 chars, keyword in the first half. Crawl for duplicates and missing titles.

Check 12 — Search intent match. For your top 10 target keywords, look at what's ranking. Does your content match the format Google rewards? If the SERP is all listicles and you wrote a how-to, you won't rank.

Check 13 — Thin & duplicate content. Find pages under ~300 words or near-duplicate pages. Consolidate or improve.

Check 14 — Keyword cannibalisation. Multiple pages targeting the same keyword compete with each other. Find them (search site:domain.com keyword) and consolidate.

Phase 5 — Content gaps

Check 15 — What ranks on page 2? In Search Console, filter for queries where you rank positions 11-20. These are your fastest wins — a small push often moves them to page 1.

Check 16 — Competitor content gaps. What topics do your top 3 competitors cover that you don't? Those are your content backlog.

Phase 6 — Links

Check 17 — Backlink velocity vs competitors. Are competitors earning links faster than you? If so, you'll fall behind regardless of content. This is usually the real ceiling on competitive rankings.

Check 18 — Anchor text distribution. Mostly branded/URL anchors is healthy. A high % of exact-match commercial anchors is an over-optimisation risk.

Check 19 — Link quality. Are your links from real, relevant, trafficked sites? Or thin directories and irrelevant domains?

Phase 7 — Diagnosis

Check 20 — Synthesize. You've now got a list of issues. Sort them into:

Fix Critical first. Then High. The Medium and Low items matter far less than people think.

The thing most audits get wrong

They treat every issue as equal weight. They don't.

For most sites, 80% of the available upside lives in 4-5 issues: indexation, internal linking to money pages, content-intent match, and link velocity. The other 195 items on a typical "200-point audit" collectively matter far less.

So: find the Critical and High issues, fix those, and move your energy to content and links — which is where compounding growth actually comes from.

This is a self-serve version of the 25-point audit I run for clients. If you'd rather have me run it on your site live and tell you the 3 biggest gaps, request a free audit — 30 minutes, no pitch.
