If you consider that your website is professional, then you must take care that all the links in it point correctly, because few things give such a bad image on a website that the links are not updated.
Fast Link Checker is a tool to be used when a link (link) no longer points to a correct site, as the author has changed his domain name or has simply hosted it on another site on the same page.
What it does is check the old link in the main search robots of the best Internet search engines (Googlebot, MSNBot, Alexa, etc.) by locating all the websites that contain that specific link (it allows analyzing not only via http, but also FTP ).
You can free download Fast Link Checker 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
