I was wondering now we saw that there is a google duplication filter how this effects blog solely based on rss feeds.
( go to http://www.google.com/search?hl=en&q=%22Virgin+Teen+Lesbians+Episode+25%22&btnG=Google+Search found 1120 sites, go to page 4, 36 of 1120 are displayed in the search results, 1048 sites are filtered )
The point of blogs feeded with rss feed is to get search engine traffic and to bring in some $. But when you are hidden from the search results you won’t get much search engine traffic at all. Meaning that you won’t get much $.
The only way to be in the visible search results again is to make your blog stand out of the crowd of other blogs using the same rss feeds. Which in generally means work.
Everyone submits to blog directories, so you can’t make much difference with that one. Everyone link trades with other or their own blogs, no much difference there too.
And in generally rss feeded blogs aren’t there to spent a lot of time at, so if you don’t you will get no or very little search engine traffic. Meaning that the actual point (getting SE traffic) of rss feeded blog is not reached, meaning that these blogs are kind of useless without you spending extra work on them.
If you are going to spend extra work on them, why not go for the more quality blogs: you get more search engine traffic and your blogs are future proof (cause search engine can change the rules of the game any time) and many more benefits. Or go with scripts that can rewrite rss feeds so that they will become unique.
Just some thoughts..
