How often does Google update their information for the new content in their index? What is their current policy as per 2011? I have noticed that Google gives same value to the content that was posted almost 2 years ago. Can't Google just show newest content and eliminate old content from it's database? In other way, Google should't crawl the content where no update has been made. Regards Theodore Sumrall
Why should old content be removed? If it ranks well, then it deserves to be on Google's search - especially if its relevant and has a ton of unique content, you're nuts.
google are a bit schiz about this. on the one hand they crawl and index as much new content as possible. their efforts to cover as many pages as quickly as possibly far outdoes the best efforts by bing and the rest. on the other hand they don't trust new sites, perhaps justifiably, and old stale content ranks well. it's a formula that seems to be working for them.
The internet would be awful if only new contents were displayed. What if you are searching for documentation or API for programs that have been out for more than a few years (you know, like PHP. Noone ever uses PHP do they?). You'd never find anything and people would have to contantly rewrite documentation, and you'd end up with the first few hits being some useless blog not the official documentation. I'd prefer an indication of HOW old the content is though, like if you're looking for software documentation and don't want something 10 years old to come up first because you're looking for the most recent version, not the one that ran on windows 3.11.
My site was crawled and indexed multiple now and now all of sudden it is showing all old page in cache.
Sometimes a new content is more needless than 3 years old one... So Google should use both old and new.
Maybe those old contents are getting updated recently? Regularly updated contents are considered new.
