The SortSite tool is an instrument for testing websites in order to detect usability problems, connected with broken links.
When user visits a website and accidentally clicks the broken link, he is redirected from your site or cannot get the needed page.
Or, for example, if your website has some broken links, the search engines can not always display your web pages in the search results.
That is why it is very important to check all your website's links to improve the usability of the site for your customers.
The SortSite tool will suit you for this purpose as well as possible.
