Run a quick on page and technical SEO check on any URL
Enter a page URL and an optional target keyword. The tool fetches the page and reports passes, warnings and failures across indexability, on page elements and delivery, with a score and a Fix First list.
A full SEO audit takes a crawler and hours. A quick check takes a URL. This tool fetches one page and tests the basics that block or weaken it: the status code, HTTPS, redirects, noindex, canonical, robots.txt, a sitemap, the title, the meta description, headings, content length, links, structured data, Open Graph tags, the mobile viewport, language, favicon and page delivery.
The results come in three groups. Indexability and server covers status, HTTPS, redirects, noindex, canonical, robots.txt, sitemap and llms.txt. On page covers title, description, headings, content, images, links, structured data and Open Graph. Delivery covers fetch time, HTML size, HSTS and compression. A switch decides whether the tool also checks robots.txt, the sitemap and llms.txt.
A score and a Fix First list put the most important problems at the top. Like every checker, it sees the HTML the server returns. It is a screening tool for one URL, not a crawl of your whole site.
- 24 checks in my run
- Three result groups
- Score and Fix First list
- Optional target keyword
- Robots, sitemap and llms.txt switch
- Free, no signup
Check a page in three steps
Press Check website or Ctrl+Enter.
- Enter the page URL. Use the full address, including https. You can load the example domain first.
- Add a target keyword and choose the extras. The keyword is optional. Leave the extras switch on to check robots.txt, sitemap and llms.txt.
- Read the score and fix the top items. Start with the Fix First list, then work through failures and warnings.
| Field | What it does |
|---|---|
| Page URL | The page to fetch and test. |
| Target keyword | Optional. Checks whether the keyword appears in key places. |
| Also check robots.txt, sitemap and llms.txt | Adds site level file checks. |
| Score | A summary of passes, warnings and failures. |
| Fix First | The most important problems, ranked. |
One real run on example.com
I ran the example domain, https://example.com/, with the extras switch on. It is a tiny reference page, so it fails a lot. That made it a good test of the report. The tool found 10 passes, 9 warnings and 2 failures, a score of 67 and the verdict “Fix the warnings”.
The failures were a missing H1 and a content length of only 25 words in the HTML. The title was 14 characters, which the tool says is short of its 30 to 60 character guide. There was no meta description, no canonical tag, no robots.txt (a 404), no sitemap, no structured data and no Open Graph tags. Passes included HTTP 200, HTTPS, no redirect, no noindex, the mobile viewport, language, favicon, fetch time, HTML size and compression.
| Item | Result |
|---|---|
| Passed | 10 |
| Warnings | 9 |
| Failed | 2 |
| Score | 67 |
| Status | HTTP 200 |
| Status and check | Result |
|---|---|
| Fail, H1 heading | No H1 found in the HTML |
| Fail, Content length | 25 words in the HTML |
| Warn, Title tag | 14 characters |
| Warn, Meta description | None found |
| Pass, HTTPS | Final URL uses HTTPS |
The three groups
Check names come from the real run.
Indexability and server
HTTP status, HTTPS, redirects before the page, noindex in the meta tag or header, canonical tag, robots.txt, XML sitemap and llms.txt.
Title and meta description
Length against a guide of about 30 to 60 characters for titles, and whether a description exists.
Headings and content
H1 and H2 presence, and how many words the HTML contains.
Images and links
Image checks and link checks, reported as info or warnings.
Structured data and Open Graph
Whether the page has schema markup and social preview tags.
Mobile, language and favicon
The viewport tag, the language attribute and a favicon link.
Delivery
Fetch time, HTML size, HSTS header and compression.
What a one page check cannot see
Use it as a first pass.
One URL, not a crawl
It tests one page. Site wide problems such as duplicate titles or orphan pages need a crawler.
It reads the HTML the server returns
Content added by JavaScript after load may not be counted. The tool says “in the HTML”.
The score is the tool’s own
67 is a summary of passes and fails. It is not a Google score and does not predict rankings.
Guides are rules of thumb
The title length guide of 30 to 60 characters is a heuristic, because Google truncates by pixel width.
Some checks are informational
Items such as llms.txt and HSTS show as info or warnings, and are not ranking requirements.
Checked from my server
Results come from my server, so geo targeted or logged in pages can look different to you.

This tool, a crawler and Search Console
They answer different questions.
| Option | Best for | Weakness |
|---|---|---|
| This website SEO checker | A fast one page screen with a Fix First list | One URL, server fetched HTML |
| A site crawler | Every page on a site | Slower and heavier |
| Google Search Console | What Google sees and indexes for your own site | Needs access and shows data with a delay |
| Redirect checker | Tracing redirect chains in detail | Not a full page check |
How this page was checked
From my SEO work
I screen pages this way before a full audit.
Run on a real sample
The 10 passes, 9 warnings, 2 failures and score of 67 come from one live run on example.com.
Limits stated up front
I say what a one page HTML check cannot see, including JavaScript content and site wide issues.
Website SEO Checker FAQ
Quick answers on checks, scores and what a one page test cannot see.
What does the website SEO checker do?
It fetches a URL and tests indexability, on page elements and delivery, then gives passes, warnings, failures, a score and a Fix First list.
Is it free?
Yes. There is no signup.
Does it crawl my whole site?
No. It checks one page, plus robots.txt, the sitemap and llms.txt if you leave the extras switch on.
What is the target keyword for?
It is optional. It lets the tool check the keyword against key page elements.
What does the score mean?
It is the tool’s own summary of passes and fails. My example scored 67, with the message to fix the warnings. It is not a Google score.
What is in the Fix First list?
The most important problems, such as a missing H1, thin content, a short title, no robots.txt or no meta description.
What did the example show?
Example.com had 10 passes, 9 warnings and 2 failures, a missing H1 and 25 words of content in the HTML.
Is a missing meta description an error?
The tool treats it as a warning. Google may write its own snippet, so a good description is worth adding but is not required.
Is llms.txt required?
No. The tool shows it as info and says it is optional. As far as I know, Google does not need it for its AI features.
Why did my title get a warning?
The tool compares length with a guide of roughly 30 to 60 characters. Google truncates by pixel width, so treat it as a rule of thumb.
Does it see content added by JavaScript?
The tool reports what is in the HTML the server returns, so scripted content may not be counted.
Why can the result differ from my browser?
The check runs from my server. Pages that change by country, login or cookies can differ.
Does the tool send my URL to a server?
Yes. A browser page cannot fetch other sites, so the URL goes to my server for the check. I have not described how long it keeps URLs, so avoid private pages.
Can it check pages behind a login?
No. It fetches the public page as a visitor would.
Will fixing every warning raise my rankings?
I cannot promise that. Fixes remove problems that can hold a page back, but rankings depend on many factors.
What should I use next?
Trace any redirect with the redirect checker and add missing files with the robots, sitemap and llms.txt generators.
