How to do a complete SEO audit (free, step by step)
An SEO audit is a health check that finds what stops a website from ranking on Google and getting cited by AI search. This free tool checks one page in about 20 seconds: whether search engines can crawl and index it, how its title, headings and content are built, how fast it loads (Core Web Vitals), whether links and images work, and whether it is secure and ready for AI answers. It then gives you a prioritised plan with fix steps for your exact CMS.
What is an SEO audit, and why does it matter?
Picture a bakery owner in Dhaka who spends a month on a beautiful new website. Six weeks later it still does not show up when people search "birthday cake delivery Dhaka". Nothing looks broken. But behind the scenes the theme left a "discourage search engines" box ticked, the homepage has no H1, and the hero photo weighs 4 MB. Each problem is small. Together they make the site invisible.
An SEO audit finds those hidden problems before they cost you customers. It looks at the page the way Google, Bing and AI assistants do: can they reach it, understand it, trust it and load it quickly on a phone? Google's own SEO Starter Guide says the same thing in its own words: make pages easy to crawl, easy to understand and useful to people.
What does this free SEO audit tool check?
Most free checkers look at a title, a description and a heading count. This tool runs more than 100 checks across ten categories, from the server response down to how AI crawlers are treated in your robots.txt.
Status codes, redirect chains, noindex, robots.txt, XML sitemap, canonical tags, soft 404s, HTTP to HTTPS and www consistency, hreflang.
Title and meta description length with a real Google preview, H1 and heading outline, keyword focus, clean URLs and language.
Word count, readability score, text-to-code ratio, lists and tables, content freshness and top keyword phrases.
Google PageSpeed scores, real-user LCP, INP and CLS, server response, compression, caching and render-blocking files.
Live broken-link test, internal links, empty anchors, alt text, image weight, WebP and lazy loading.
SSL expiry, mixed content, security headers, Open Graph, JSON-LD validation, AI crawler access, llms.txt and FAQ content.
It also identifies your platform. The tool recognises WordPress (with its theme, page builder and SEO plugin), Shopify, Wix, Squarespace, Webflow, Joomla, Drupal, Ghost, Blogger, BigCommerce, Magento, HubSpot, Framer, Duda and more than 40 other systems, frameworks, CDNs and analytics tools. That is how it can tell a WordPress user "open the Rank Math panel" and a Shopify owner "scroll to Search engine listing".
How do I use the free SEO audit tool?
- Enter a page addressType your domain or paste any page URL. Start with your homepage, then audit your top service, product or blog pages one by one, because every page has its own title, content and speed.
- Pick mobile or desktopMobile is the default because Google indexes the mobile version of your site first. Switch to desktop to compare.
- Run the auditThe tool opens the page from our server, follows redirects, reads robots.txt, the sitemap and the SSL certificate, tests up to 50 links and 25 images, then asks Google PageSpeed for Core Web Vitals.
- Work through the action planIssues are grouped into Fix first, Fix next and Then polish. Click any item to see why it matters and numbered steps for your CMS, with copy-ready code where it helps.
- Save, share and re-testDownload a PDF or CSV for your developer, copy a share link, then run the audit again after your changes. The tool remembers your last score so you can see the improvement.
Tip: if a firewall such as Cloudflare's "Under attack" mode or a security plugin blocks the audit, try another page or briefly allow it. If our tool is blocked, check that Googlebot is not blocked too, using Search Console's URL Inspection.
How do I read my SEO score?
Every check is marked Critical, Warning or Passed and weighted by impact. A missing title or a noindex tag counts far more than a missing Apple touch icon. Each category gets a score out of 100, and the overall score is a weighted average in which crawling, on-page SEO and speed matter most.
| Score | Grade | What it means |
|---|---|---|
| 90 to 100 | A | Excellent technical health. Focus on content, links and conversions. |
| 80 to 89 | B | Strong. A few fixes will remove the last friction. |
| 70 to 79 | C | Average. Fix the critical items first; these often unlock quick gains. |
| 55 to 69 | D | Several problems are likely holding rankings back. |
| Below 55 | F | Serious issues. Start with the Fix first list today. |
Treat the score as a to-do list, not a verdict. A page with a score of 95 and weak content will still lose to a page with a score of 80 that answers the searcher better. Google ranks pages for usefulness; technical SEO makes sure that usefulness can be seen.
What are good Core Web Vitals scores?
Core Web Vitals are Google's three measures of real user experience. Google classes a page as good when at least 75 percent of visits meet each target, according to web.dev's thresholds guide.
The report shows two kinds of numbers. Real-user data comes from the Chrome User Experience Report and covers the last 28 days of visits; it only exists for pages with enough traffic. Lab data comes from a fresh Lighthouse test on a simulated mid-range phone. When both exist, trust the real-user data for how you are doing and use the lab test to find what to fix.
The most common fixes are the same on every platform: compress and resize images, avoid lazy loading the first big image, remove apps or plugins you do not use, defer non-essential JavaScript, and set width and height on images and embeds.
Does it work for WordPress, Shopify, Wix and other CMS?
Yes. The audit reads the finished page the same way a search engine does, so it works on any website that loads in a browser. What changes from one platform to another is where you fix things, and that is where most generic tools stop being useful.
Fixes refer to your actual SEO plugin (Yoast SEO, Rank Math, AIOSEO or SEOPress), your page builder such as Elementor, and common speed plugins. If no SEO plugin is found, the first step is installing one.
Steps point to Search engine listing fields, Online Store Preferences, URL redirects, theme.liquid and robots.txt.liquid, plus app clean-up for speed.
Steps use SEO basics, the URL Redirect Manager, structured data markup, Page settings and Code Injection, and flag the few things these platforms do not let you change.
Each has its own instructions. For custom sites and frameworks such as Next.js or Laravel, you get plain HTML and server snippets.
If the detection is wrong, for example on a headless site, use the "Show fixes for" menu in the report to switch platforms.
Is my website ready for AI search?
People now get answers from Google AI Overviews, ChatGPT, Perplexity and Claude, and those answers link to sources. Google states that there are no extra requirements to appear in its AI features beyond normal SEO best practice, according to its AI features documentation. In practice, the sites that get cited share a few traits, and the AI readiness category checks them:
- AI crawlers are allowed. If robots.txt blocks GPTBot, OAI-SearchBot, ClaudeBot or PerplexityBot, those assistants cannot read your pages. Blocking them is a valid choice, but you should make it on purpose.
- Content is real text in the HTML, not built entirely by JavaScript, with lists and tables that are easy to quote.
- Pages answer questions directly, with question-style headings and a short FAQ.
- The source is clear: an author or organisation, an About page and Organization or Person schema.
- Optional extras such as an llms.txt file, an emerging proposal from llmstxt.org. It is quick to add but not proven to change citations, so the tool treats it as low priority.
What should a manual SEO audit checklist include?
The tool covers one page at a time. For a whole site, combine it with these free checks once a quarter:
- Google Search Console: open Pages (indexing) to see which URLs are excluded and why, and Core Web Vitals for site-wide speed groups.
- Search your brand and main service on Google and in an AI assistant. Note who outranks you and what their pages cover that yours do not.
- Audit your top ten pages here, starting with those that bring leads or sales.
- Check for duplicate titles and thin pages in your SEO plugin or a crawler, and merge or improve weak ones.
- Review internal links so every important page is reachable within three clicks of the homepage.
- Validate structured data with Google's Rich Results Test, following Google's structured data introduction.
- Review robots.txt after every redesign; Google's robots.txt guide explains what it can and cannot block.
- Check your Google Business Profile if you serve a local area: name, address, phone, hours and reviews.
How often should I run an SEO audit?
Run a quick audit of your key pages once a month, and always after a redesign, a theme or plugin change, a platform migration or a big content update. Those are the moments when noindex tags, broken redirects and slow scripts slip in. A deeper site-wide review every three to six months is enough for most small business websites.

Frequently asked questions
Is this SEO audit tool really free?
Yes. There is no sign-up, no email gate and no limit on the number of reports you can download. A fair-use limit of about 15 audits every 10 minutes per visitor keeps the free server fast for everyone.
Does the SEO audit work for WordPress, Shopify, Wix and other platforms?
Yes. It audits any public website because it reads the finished page like a search engine. It detects more than 40 platforms and writes the fix steps for WordPress, Shopify, Wix, Squarespace, Webflow, Joomla, Drupal, Ghost, Blogger, BigCommerce, Magento or custom code, and you can switch platforms in the report.
What does the SEO audit check?
More than 100 checks in ten categories: crawling and indexing, on-page SEO, content quality, speed and Core Web Vitals, links, images, mobile usability, security and trust, schema and social tags, and AI search readiness.
Why is my score different from other SEO tools?
Every tool weights issues differently and some only check a handful of items. Use the score to track your own progress over time and focus on the critical issues in the action plan rather than chasing a perfect number.
Why does the Core Web Vitals section say Google is busy?
Speed data comes from Google's free PageSpeed Insights service, which sometimes limits requests. The rest of the report still works. Press Try again after a minute or open the full PageSpeed report link.
Can I audit my whole website, not just one page?
The tool audits one URL at a time in depth, plus site-wide items such as robots.txt, the sitemap, SSL, HTTPS and www redirects. Audit your homepage and your most important service, product and blog pages one by one, and use Google Search Console for a site-wide indexing view.
Is my website data safe?
The tool only reads public pages, the same way Google does. It does not log in, change anything or store your site content beyond a short cache of about 15 minutes, and your recent audits are saved only in your own browser.
Why did the audit fail for my site?
Usually a firewall or security plugin blocked the request, the domain is misspelled, or the server took more than 15 seconds to respond. Check the address opens in your browser, then try again or test another page.
How do I share the report with my developer?
Use PDF report to print or save a clean report, CSV of issues to open the task list in Excel or Google Sheets, or Share link to send a link that reruns the audit for the same page.
How often should I run an SEO audit?
Check your key pages once a month and always after a redesign, plugin or theme change, migration or big content update. A full site review every three to six months is enough for most small business websites.
