Free Website Audit Tool

What a full site audit checks

Most problems that hold a site back fall into five groups. This free website audit runs a quick check in each one and shows them side by side, so you can see the weak spots at a glance.

• On-page SEO: title, meta description, H1 and heading order, image alt text, canonical tag, noindex, social share tags, structured data, response time and HTML size.
• Links and images: up to 25 links and 15 images on the page are tested, and any that fail are listed.
• HTTPS and redirects: the four versions of your domain (http, https, with and without www) should all land on one secure address.
• Security: signs of injected code, known backdoor file names, SSL certificate, security headers, mixed content and exposed WordPress details.
• Crawling and indexing: whether robots.txt lets Googlebot reach the page, and whether an XML sitemap can be found.

How to use the website audit tool

1. Enter your homepage, or any important page such as a product or service page.
2. Click Run Full Audit and wait. Most audits finish in under a minute.
3. Read the overall score, then open each area to see its own score and issues.
4. Use "Open the detailed report" under any area to run the full tool for that topic, with your URL already filled in.

How the score works

Each area gets a score out of 100. The overall score is a weighted average, because some problems matter more than others: on-page SEO counts for 30%, security 25%, links 20%, crawling 15% and HTTPS 10%. A letter grade from A to F sits next to the number so it is easy to share with a client or your team.

The score is a guide, not a ranking promise. A page can score 100 and still struggle if its content does not answer what people search for. What the score does tell you is whether technical problems are getting in the way.

What to fix first after a full site audit

1. Anything that hides the site: a noindex tag on an important page, robots.txt blocking Googlebot, or an expired SSL certificate. These can wipe out traffic on their own.
2. Security warnings: injected scripts, backdoor files and mixed content put visitors at risk and can lead to browser warnings.
3. Broken links and images: they waste visits and make the site look neglected.
4. On-page details: titles, descriptions, headings and alt text. These are quick to fix and help every page you publish later.

How often to run a website audit

Run it once a month, and again after any big change: a new theme, a plugin update, a migration or a redesign. Your browser remembers your recent scans, so running the same audit again takes one click. Keep a copy of each report with Print or save as PDF, and you will have a simple record of how the site improves over time.

The full site audit looks deeply at the page you enter plus your site-wide settings. To cover more pages, follow up with the multi-page SEO check, which crawls up to 12 pages in one go.
