This tool crawls your entire site and then analyzes all your pages for duplicate content. It shows similarity percentage among all pages on your site, so you can see what pages are similar enough to trigger a flag in major search engines and consequently they can penalize your site for duplicate content. The higher the similarity, the more likely that you will zapped by them Below is its screenshot and I think the tool doesn’t require any how-to as it is quite simple. If you have any comment, questions or anything else, please let me know. You can download it here. P.S – This tool is NOT intended for large websites and has a lot that can be improved.
Actually, the site is hosted on HostGator and it has been down many times in the last few days. I had to email their support to get it back. It is up again.
on his site This tool is NOT working at the moment as the Web-based PHP script that used to compare the % of duplicate content among pages for it has been disabled by the host since it was causing a high load on the server. It won’t work till I get a dedicated server of my own to host it and update this tool. Thanks!
