Website SEO checker for a fast on-page health check
Enter a domain and SeoData checks the homepage the way a search engine sees it. Status, HTTPS, response time, robots rules, sitemap, indexability, tags, headings, images, structured data and links are measured live by our own crawler, and the top issues are ranked for you.
What the checker measures
Every number in the report is measured at the moment you run it. Nothing is guessed.
| Area | What SeoData checks |
|---|---|
| Status | HTTP status code and the full redirect chain |
| HTTPS | Whether the page loads over HTTPS and redirects from HTTP |
| Speed | Time to first byte from our crawler |
| Robots | robots.txt rules for the major search crawlers |
| Sitemap | Whether a sitemap is found and how many URLs it lists |
| Indexability | Meta robots, canonical tag and X-Robots-Tag header |
| Title and meta | Length of the title and meta description against recommended ranges |
| Headings | H1 count and the full heading outline |
| Images | Share of images with alt text |
| Structured data | Schema types found on the page |
| Hreflang | Language and region annotations |
| Open Graph | Title, description and image for social sharing |
| Links | Internal links, outbound links, external domains and nofollow share |
Top issues, ranked
After the checks SeoData ranks the problems it found by impact. A page that cannot be indexed comes before a title that is a few characters too long. A short summary lists three to five actions written from the real findings.
How a check runs
Enter your domain and pick the market.
SeoData resolves the domain, reads robots.txt and the sitemap, crawls the homepage and checks its links.
You see each step as it completes, then the full on-page report.
Our crawler respects robots.txt. If the site blocks it, the report says so plainly.
One page today, the whole site with a plan
The checker looks at a single page. A full site audit tool crawls every page on a schedule, groups issues by category and catches regressions after each release. With an account you also unlock visibility, the backlink profile from our backlink checker and a keyword gap against a competitor.
Who runs a quick SEO check
- Marketing managers checking a page before a launch or a campaign.
- Developers confirming that a release did not break indexing or redirects.
- Agencies taking a first look at a prospect's site.
- Consultants who need a fast, factual starting point for a conversation with a client.
Reading your report
Start with indexability. If the page is blocked by meta robots, a canonical points elsewhere or robots.txt disallows it, nothing else matters until that is fixed. Next check status and HTTPS: one clean redirect to the HTTPS version is the goal. Then look at the title, meta description and H1, because they shape how the page appears in results. Finally review links and structured data. The AI SEO recommendations inside the app turn findings like these into a ranked plan for the whole site.

Website SEO checker questions
Which page does the checker test?
It tests the homepage of the domain you enter, after following redirects. Full site audits on any plan cover every page.
Why is my time to first byte different from my own test?
Response time depends on location, network and server load at that moment. SeoData measures from our crawler and shows the exact value it received.
Can I try SeoData before I pay?
Yes. Run one domain snapshot from this page without an account. Visibility, backlinks and keyword gap open with any plan.
