How to use it

Run the tools in section order. Each section is one part of the audit.
Paste every problem into the fix-list template at the end as you go.
Fix in this order: can't be found > can't be read > slow > everything else.

1. Can Google find and keep your pages?

Google Search ConsoleFree · needs site verification
Google's own report on your site. The Pages report shows what isn't indexed and why; URL Inspection shows how Google sees one page.
Best for: The first and most important audit check.
Ritik's note: Open Indexing > Pages. Only worry about reasons on pages you actually want in Google. Google says many 'not indexed' reasons are normal.
Bing Webmaster ToolsFree · import your site from Search Console
Bing's version of Search Console, with a Site Scan that crawls your site and lists SEO issues.
Best for: A second crawler's view of your site, and Bing/Copilot data.
Ritik's note: Site Scan was reported at launch (2020) to crawl up to 10,000 pages a month. Check the current cap inside the tool.

2. Crawl the site like a search engine

Screaming Frog SEO SpiderFree · up to 500 URLs per crawl (paid licence £199/year)
Desktop crawler that finds broken links, redirects, missing or duplicate titles and descriptions, and noindex tags.
Best for: Small sites. 500 URLs covers most local business and early SaaS sites.
Ritik's note: Sort Response Codes by Client Error (4xx) first. Every broken internal link is a dead hallway.
Ahrefs Webmaster ToolsFree for verified sites · 5,000 crawl credits per project per month · 1,000 backlinks/keywords shown
Free cloud Site Audit plus Site Explorer for your own backlinks and keywords.
Best for: A monthly health score that runs without your laptop.
Ritik's note: Verify through Search Console in a couple of clicks.
httpstatus.ioFree web checker · up to 100 URLs at once
Bulk checker for status codes and redirect chains.
Best for: Checking that http, www and old URLs all redirect in one hop to the right page.
Ritik's note: Paste your four homepage versions (http/https, www/non-www). All should 301 to one URL.

3. Speed and Core Web Vitals

PageSpeed InsightsFree · no account
Real-user Core Web Vitals (when Google has enough data) plus a Lighthouse lab test with fixes.
Best for: Checking LCP (2.5 s or less), INP (200 ms or less) and CLS (0.1 or less) on key pages.
Ritik's note: Mobile tab first. Test your homepage and your main money page.
Lighthouse (Chrome DevTools)Free · built into desktop Chrome
Built into Chrome. Audits performance, accessibility, best practices and SEO for any page you open, including staging sites.
Best for: Testing pages before they go live.
Ritik's note: Lab tests can't measure INP; Lighthouse uses Total Blocking Time as a stand-in.

4. Schema and rich results

Rich Results TestFree · live URL or pasted code
Google's test for which rich results your structured data can earn, and errors that block them.
Best for: Checking Product, LocalBusiness, Breadcrumb, Article and other Google-supported types.
Ritik's note: FAQ rich results were retired in 2026, so don't expect FAQ stars here.
Schema Markup ValidatorFree · no account
Schema.org's validator for every schema type, not only Google's rich result types.
Best for: Catching errors in Organization or LocalBusiness markup the Rich Results Test ignores.
Ritik's note: Use both tools. They answer different questions.

5. Can AI assistants read your site?

theStacc AI Visibility CheckerFree · no signup · a limited number of checks per visitor in a short period
Requests a page as seven AI crawlers (including GPTBot, OAI-SearchBot, ClaudeBot and PerplexityBot) and a normal browser, reads your robots.txt rules for each, and checks text before JavaScript, noai/nosnippet, llms.txt and structured data.
Best for: Spotting a robots.txt rule or firewall that blocks AI crawlers by accident.
Ritik's note: Run it on your homepage and one service page. It only checks access and readability, not rankings.

Business info consistency (manual check, no tool needed)

Business name, address and phone are identical on your site footer, contact page and Google Business Profile.
Google advises keeping Business Profile information accurate and current; mismatches confuse customers. (Practical advice on exact matching.)
Opening hours on your site match your Google Business Profile, including holiday hours.
Wrong hours lose walk-ins and calls.
Any LocalBusiness or Organization schema uses the same details as the visible page.
Google's structured data guidelines require markup to match visible content.

FAQ

Frequently asked questions

Can I do an SEO audit myself for free?

Yes, most of it. Search Console, Screaming Frog's free version (up to 500 URLs), PageSpeed Insights and the Rich Results Test cover indexing, crawling, speed and schema.

How often should I audit my website?

Practical advice: a full audit after any redesign or migration and every few months otherwise, plus a weekly look at Search Console's Pages and Core Web Vitals reports.

Is 'Crawled - currently not indexed' a problem?

Not always. Google says it may index the page later and you don't need to resubmit. It matters if it keeps happening on pages you need in Google.

What should I fix first after an audit?

Anything that stops important pages being found or indexed, then problems reading the page, then speed, then everything else.
