As I know, search engines like Google expect a webpage to have a reasonable amount of content. I am running a twitter-like website, as users can post 140 characters. Twitter makes each tweet as a page, and obviously it has a very short content. Google fairly indexes these tiny pages. However, this is about a giant named Twitter, I doubt if Google fairly treat small websites with the same structure. Do you have any comment, advice, or suggestion about how to improve SEO for such websites? Is it really bad to have individual webpage of each tweet? if yes, how to overcome the problem?
