Full website scan

Four audits in one pass: SEO, link checking, accessibility and server analysis. Every page is opened in a real browser, and every problem comes with an address and a fix.

• All services

A site rarely breaks in one place. A redirect added during a redesign quietly sends half the internal links through two hops; a template change drops the meta description from every product page; a new banner makes the menu unreachable from the keyboard; the CDN stops sending caching headers. Each of these is easy to fix and hard to notice. The full scan brings four audits together so that you see the whole picture in one report instead of four tools and four exports.

SEO audit

The scanner reads each page the way a search engine does and checks what decides whether the page is indexed and how it is shown in the results:

• the title and meta description — presence, length, duplicates across pages;
• headings — a single h1 and a logical outline;
• canonical, hreflang and the language of the page, so that the right version of the page is indexed in the right country;
• robots.txt, noindex directives and the XML sitemap — whether they agree with each other and do not hide important pages;
• structured data (Schema.org), Open Graph and Twitter cards — what the page looks like in search results and when shared;
• the answer for a non-existent address: a "soft 404" that answers 200 ends up in the index as a real page.

Link checking

Every internal link found during the crawl is followed. The report lists broken links (404, 410, 5xx), redirect chains and loops, links from HTTPS pages to HTTP, missing images and icons. For each broken link you see not only the target but also the page it was found on, so it is clear what to edit. External links are checked for availability too, so the site does not send visitors to dead pages.

Accessibility audit

Accessibility is checked with axe-core, the engine behind most professional tools, run in a real browser on the rendered page rather than on the raw HTML. It finds missing alternative text, form fields without labels, insufficient contrast, buttons without names, broken heading order and ARIA errors. On top of the automated rules, the scanner opens the site at phone size and actually uses it: it reaches the menu with the Tab key, opens and closes it, checks that focus is visible and returns where it should. This is the part of WCAG that automated rules alone cannot see.

Server analysis

The last part looks at the infrastructure the pages are delivered from:

• response times and Core Web Vitals — LCP, CLS and INP from real Chrome user data where available, and from a lab measurement otherwise;
• HTTP/2 and HTTP/3, compression, caching headers and validators (ETag, Last-Modified);
• the number of redirects between the entered address and the final page, the HTTPS redirect and the www variant;
• the TLS certificate, its expiry date and supported protocol versions;
• DNS: name servers, IPv6, mail records, domain registration and expiry dates.

Rendering like a real visitor

Many modern sites assemble the page in the browser with JavaScript; a crawler that reads only the HTML sees an empty template. SiteScan.top opens every page in Chromium, waits for it to render, records JavaScript errors from the console and takes a screenshot. What the report describes is what visitors actually see.

The report

All four audits end up in one report with an overall score and a score for each area. The most valuable fixes are collected at the top as "quick wins": what to do first to get the biggest effect for the least work. Each finding lists the affected pages, explains the problem in plain language and suggests a fix. The report can be shared by link, downloaded as PDF or copied as a brief for a developer or a contractor.

Scale and monitoring

A free scan covers the start page and the pages linked from it — enough to evaluate a landing page or a small site. For a larger site the crawl goes deeper and is paid for with tokens, one token per page checked, without a subscription. Put the site under monitoring and the scan is repeated on a schedule: the report shows what got better and what broke since last time, and a notification arrives when something important changes.
