We all know that search engines have strange quirkes when it comes to filtering the indexes they have. Well very recently it came to my attention that Google has added some new extensions to the filter list.
We already new that files with .exe, .dll and .lib were being filtered from the search results. Which I think is a good thing, as it protects the visitors from potential harm. But just a few days back I got word that Google is now also banning or blocking pages ending on .0.
Some examples are:
- The wikipedia page Web 2.0 (http://en.wikipedia.org/wiki/Web_2.0) ending in .0 is no longer showing up in the search results, rather the page ending in 2 (http://en.wikipedia.org/wiki/Web_2).
- The Seomoz page for Web 2.0 has disappeared from the results. Instead the summary page is listed.
After some chatter about the issue around the internet and blogs Matt Cutts wrote a quick entry in his blog as to why they have been removed from the search results. Read it at http://www.mattcutts.com/blog/dont-end-your-urls-with-exe/.
So for know try to avoid ending Url’s with .0 or any of the already known blocked extensions.
