What does the SEO score measure?

It is a weighted average of twelve category scores built from the individual checks, with Technical and On-Page at 20% each and Indexability at 15%. It shows how many checks the page passes, not how it will rank.

Which checks does the audit run?

HTTP status, HTTPS, redirects, canonical and robots tags, title, description and headings, indexing headers, robots.txt and sitemap, word count and language, links, image alt text, JSON-LD, Open Graph and Twitter tags, page size, scripts, compression, viewport and several security headers.

Does the checker obey robots.txt or run JavaScript?

Neither. It requests the page directly with the AuraTools-SEO-Auditor/1.0 user agent. It fetches robots.txt only to see whether the file exists and lists a sitemap, and it executes no scripts, so client-rendered content is invisible to it.

Can I share a report with someone else?

Yes. Share this report creates a read-only link to the computed results, and you do not need an account. The stored report holds scores and findings, not the page's HTML. Signed-in users can also file shared reports under projects.

Is the URL I enter sent to your server?

Yes. The audit needs our server to download the page, so the address goes there. Results for a URL stay in server memory for 5 minutes, which is why a repeat audit can show a Cached badge. The fetched HTML itself is not kept.

About Website SEO Checker

Enter a public URL and our server downloads the page's HTML, follows redirects, looks for robots.txt and a sitemap, and runs a fixed set of rule-based checks on what it received. The report gives an overall score from 0 to 100, twelve weighted category scores, and a table of every check with its evidence and a suggested fix. Two extra panels list observable signals for AI search readiness and trust. The score comes from this tool's own rules and is not a search engine ranking.

Features

A score from 0 to 100 with a bar for each of twelve weighted categories
Checks from technical SEO and indexability to images, structured data and accessibility
Evidence and a recommendation shown for each check
Reads robots.txt and checks a sitemap listed in it
Read-only share link for a finished report

Limitations

Only the HTML the server receives is analyzed. Content added by JavaScript after the page loads is not seen, because the audit does not run a browser.
One page per run: the audit analyzes at most 2 MB of the page's HTML, follows up to 5 redirects and waits up to 15 seconds for the page.
The score is this tool's own weighted rule set. It is not a Google ranking score and does not predict traffic.
Each IP address is limited to 5 audits per minute, and a repeat audit of the same URL within 5 minutes returns the cached result.

How it works

Enter a public page address; https:// is added if you leave it out.
Press Analyze Website and wait while the audit runs on our server.
Read the SEO Score ring, the passed, warning and failed counts, and the bar for each category.
Open the Detailed Audit table, filter it by status, and read the evidence and recommendation behind each check.
Open Technical Details for the status code, response time, page size, robots.txt and sitemap findings.
Use Re-audit after a fix, or Share this report to create a read-only link.
