Quick start

To begin validating your sites you need to create an account. Once you have done that, you’ll be prompted to validate your first site.

Enter the starting URL, the maximum number of pages to validate, click “Submit” and you’re ready to go:

New site validation form

Options

To validate a site, you can define:

  • Starting URL. Our validation spider will visit this URL and its direct internal links, and validate those pages. Typically, you can enter the main URL of the site to validate, but it can be any URL from your site, or an XML sitemap.
  • Max. pages. The maximum number of pages to validate. There’s a limit of 5,000 pages per each site validation, but you’ll typically want to set a much lower limit. If you need to validate more than that, consider using XML sitemaps to organize pages into sets.

Advanced options

The advanced options let you define:

  • Max. requests per second. By default is 3 reqs/second, can be set from 1 to 25 (Pro users) or 1 to 10 (Basic users). Read more.
  • Perform accessibility checks. Enabled by default for Pro users. Disable if you want to skip A11Y checks.

Re-checking your pages

Once your site has been processed, you’ll see the HTML and accessibility issues for each page found. As you go fixing them, you can re-check the pages quickly:

  • Re-check button on each page. This will submit an individual page to the validator.
  • Re-check all pages with issues button. This will submit all pages with errors or warnings to the validator.
  • Re-check all pages button. This will submit all pages on the site to the validator.
  • Re-scrape site button. This will start the scraper again, to discover the internal pages of the site and validate each of them. Use only if the structure of your site has changed or if you want to change any parameter (like max pages).
