How it works
How the Website SEO Checker works
1) Enter any URL
Check any page — homepage, product page, or blog post. We fetch it in real time and read meta tags, Open Graph, Twitter cards, canonical, and robots rules.
2) Test and score critical SEO signals
Every signal is tested and graded into an SEO score out of 100 — flagging missing or duplicated titles/descriptions, social previews, structured data errors, and mobile/HTTPS issues.
3) Get fixes and share
Download branded PDF and JSON reports, or embed the widget to deliver audits to clients instantly. A white-label version is available on request — just ask.

FAQ
SEO website checker FAQs
Is the SEO checker free?
Yes — this search engine optimisation checker is completely free. Paste a URL and run a full technical audit at no cost. No account, no card, nothing to install.
What does the SEO checker analyse?
Meta titles and descriptions (measured against Google’s pixel display budgets), Open Graph and Twitter cards, JSON-LD structured data, canonical tags and redirects across http/https and www variants, robots.txt and meta robots directives, XML sitemap, AI crawler access (ChatGPT, Claude and Perplexity), word count and content quality, heading structure, image alt text, internal and external links, HTTPS and mixed content, and server response time.
How do I check the SEO status of my website?
Paste your page URL and run the scan. Within seconds you get a graded report of your site's SEO status — every issue explained, grouped by category, with clear fixes you can act on immediately.
Do I need to sign up or install anything?
No. The checker runs in your browser against any public URL — nothing to download and no account to create.
Is my scan data stored?
Yes — a minimal record. We keep the domain you scanned, its score, the date, and the country, IP address and browser the scan came from, so we can run and improve the service. We never store the page content, the full URL or your report — unless you click "Copy share link", which saves that report for 30 days so the link works, then it expires automatically. Ask us any time and we'll delete your domain's record. Read our privacy policy.
What is a good SEO score for a website?
Above 90 is strong, 70–89 usually means minor technical fixes, and below 70 signals missing fundamentals like meta tags, canonicals or structured data. Run a free scan to see where your website lands.
How do I check a competitor's website SEO?
Paste any public URL — the checker works on any site you can reach in a browser, not just your own. Compare a competitor's results with yours to see which signals they have that you're missing.
Does the SEO checker work on WordPress, Shopify, and Wix websites?
Yes. It audits the rendered HTML of any public website, so WordPress, Shopify, Wix, Squarespace, Webflow and hand-built sites all work — nothing to install.
How often should I run an SEO audit on my website?
Scan after every meaningful change — new pages, redesigns, migrations or CMS updates — and monthly as a baseline. Regressions are easiest to fix right after the deploy that caused them.
Can I do SEO myself or should I hire an expert?
Most technical fixes the checker surfaces are well documented and fixable yourself. For ongoing work — content strategy, link building, monitoring — our SEO team can audit, fix and monitor it for you. Book a free SEO consultation.
What is the difference between an SEO checker and a full SEO audit?
An SEO checker automatically tests technical and on-page signals in seconds. A full SEO audit adds human analysis: content quality, keyword strategy, backlinks and competitive positioning. Book a free SEO consultation.
Can I check the SEO of a single page?
Yes — paste any URL to test that page's on-page SEO: your homepage, a product page or a blog post. Each page gets its own score and fix list, so scan the URLs that matter most.
Is this an SEO health check for my site?
Yes — treat each scan as a website SEO health checkup. It tests every core technical signal, grades the page with a score out of 100, and lists the errors to fix first. Run a quick checkup after any site change.
Can I get a free SEO report for my website?
Yes. Every scan produces a free online SEO report — your score, each check's result and the recommended fixes — with a PDF you can share with your team or clients.
Does the SEO checker show my Google rankings?
No — this is a technical SEO checker, not a rank tracker. It tests and scores the on-page signals that influence how you rank: metadata, canonicals, structured data, robots rules, HTTPS and mobile readiness. For rankings tracked and lifted month over month, our SEO team can help. See our SEO services.
How does the canonical and redirect audit work?
We test the four main URL variants (http/https, www and non-www), follow redirects, and confirm the final URL's canonical tag matches the served page.
Can I compare two scans?
Yes. Compare mode highlights what changed between two scans — tags, scores and issues — so you can see what was fixed or introduced.
Can I export or share reports?
Yes. Download the report as a PDF to share with your team or clients, or embed the free widget on your own site.
What should I fix if multiple versions return 200?
Pick one preferred URL (https, and either www or non-www), redirect the rest with a 301 or 308, and make rel=canonical point at that final URL.
Is there a rate limit?
Yes. Scans are limited to approximately 30 per IP address per hour, enforced on a best-effort basis and shared across the tool and any embedded widgets.
