Free SEO Audit Tool — 72-Point Website Health Check
Enter any URL and get a graded report in seconds. The audit checks seven areas: on-page content, speed and Core Web Vitals, technical indexability, HTTPS security, mobile usability, DNS setup and links. Each issue comes with a fix.
Last updated:
The audit reads publicly available data from the URL you enter. Only test sites you own or have permission to check.
How the 72-Point Audit Works
Enter a URL, let the checks run, and read a graded report with fixes for each issue.
Fetch & Read the Page
The scanner requests your page, measures how fast your server responds (TTFB), and reads your headings, meta tags and canonical setup.
Check Speed, Security & DNS
It checks speed signals, your HTTPS certificate and security headers, and DNS records such as IPv6 and SPF/DMARC.
Get a Graded Report
You receive a grade from A+ to F, a prioritized list of issues with fix guidance, a shareable report link and an embeddable score badge.
The 7 Areas the Audit Covers
Every area feeds into your overall grade, and every issue links to a fix.
1. On-Page & Content
Checks title tags, meta descriptions, heading hierarchy (H1-H6), reading ease, content-to-code ratio and image alt text.
2. Speed & Core Web Vitals
Looks at server response time (TTFB), Core Web Vitals signals such as LCP and CLS, render-blocking assets and Gzip/Brotli compression.
3. Technical Indexability
Verifies canonical tags, robots.txt rules, XML sitemaps, JSON-LD structured data, Open Graph previews and Twitter cards.
4. HTTPS & Security
Checks your live HTTPS certificate (days until expiry, TLS version) and security headers such as HSTS, CSP and X-Frame-Options.
5. Mobile Usability
Evaluates the viewport meta tag, responsive text scaling, tap target size (48px or larger) and mobile touch icons.
6. DNS & Infrastructure
Checks IPv6 (AAAA) records, CDN detection (such as Cloudflare, CloudFront or Fastly) and SPF/DMARC email authentication records.
7. Link Architecture
Reviews internal and external links, broken links, anchor text and nofollow use, so crawlers and visitors can move through your site.
What Technical SEO Can (and Can't) Do for Your Site
A technical audit finds the problems that make a site hard to crawl, slow to load or unpleasant to use. Fixing them helps search engines read your pages and helps visitors stay on them. It won't replace good content. Google AdSense, for example, approves sites mainly on original content, required pages and policy compliance, so use the audit to clear technical obstacles, not to substitute for quality.
Core Web Vitals Targets
Google rates a page "good" when LCP is 2.5 seconds or less, INP is 200 milliseconds or less, and CLS is 0.1 or less, measured across real visits. INP replaced FID in March 2024. A one-time test like this audit gives you a snapshot. Your real-user results appear in Search Console's Core Web Vitals report.
Why TTFB Matters
Time to First Byte isn't a Core Web Vital, but a slow server response delays everything after it, including your LCP. Google's guidance treats 800 milliseconds or less as good. Caching, a CDN and faster hosting are the usual fixes.
HTTPS & Certificate Expiry
An expired certificate makes browsers show a full-page warning, and most visitors leave. The audit counts the days until your certificate expires, so you can renew early. Security headers such as HSTS add a further layer by keeping connections on HTTPS.
Layout Shifts & Ad Slots
If an ad or image loads without reserved space, the content jumps. That raises your CLS score and can cause accidental taps, which ad programs discourage. Set fixed dimensions on images and on ad containers before they load.
Canonical Tags & Duplicate URLs
A canonical tag tells Google which URL is the main version of a page. Missing, circular or wrong canonicals split signals across duplicate URLs. Pair clean canonicals with a correct robots.txt file and an up-to-date XML sitemap.
How to Use Your Score
Your grade is this tool's own summary, not a Google ranking score. Start with the highest-priority issues, fix them, then run the audit again to confirm. Re-check after every major site change, such as a redesign, a new theme or a hosting move.

SEO Audit Questions, Answered
Open any question for clear answers on what the audit checks and how to act on it.
Indirectly. AdSense approval depends mainly on original content, the pages Google expects (such as a privacy policy and contact page), clear navigation and policy compliance. An audit finds technical problems that can get in the way, like broken pages, slow responses, an expiring certificate or a poor mobile layout. Fix those, but don't expect technical scores to replace strong content.
The audit covers seven areas: (1) on-page content, including title and meta lengths, heading hierarchy and readability; (2) speed and Core Web Vitals signals, including TTFB, render-blocking resources and compression; (3) technical SEO, including canonical tags, robots.txt, sitemaps and structured data; (4) HTTPS and security, including certificate expiry, TLS version and security headers; (5) mobile usability and viewport settings; (6) DNS and infrastructure, including IPv6, CDN detection and SPF/DMARC records; and (7) link architecture.
Aim for LCP under 2.5 seconds, INP under 200 milliseconds and CLS under 0.1. To improve LCP, preload your main image, serve WebP or AVIF files and speed up your server response. To improve INP, cut and defer JavaScript so the page responds quickly to taps and clicks. To improve CLS, set width and height on images and reserve space for ad slots before they load. INP replaced FID as a Core Web Vital in March 2024.
Yes. You don't need an account or a payment to run an audit and read the full report.
Screaming Frog is desktop software that crawls whole sites. Ahrefs and Semrush are paid platforms built around keyword, backlink and competitor data. This tool is a quick online health check for the URL you enter, with an extra focus on AdSense readiness. Many site owners use a quick audit like this alongside a full crawler.
Yes. Each audit gets its own report link you can share. You can save the report as a PDF with your browser's Print dialog, and you can embed a live SVG score badge in your site footer or documentation.
No. The score is this tool's own summary, and Google doesn't use it. Treat the report as a prioritized to-do list. Fixing the issues it finds can improve crawling, speed and user experience, which are the things Google does measure.
