Hi, I have noticed recently that many articles and posts in forums that I have made in the past are gradually getting de-indexed, some of them are de-indexed due to the site PR going down, and some are not actually indexed ever, what are the most reliable sites regarding the speed of indexing and how long it will stay indexed???!
I have noticed the same thing in articles that have been submitted multiple times to different directories. I believe that it has something to do with duplicate content filters. Try using an article spinner and only post each version of your article to 3-5 article directories. That has been working for me so far so I figured I would let you know!
actually its not just the dup. articles I have unique copies on many article directories but it seem that google is decreasing the the number of indexed content all over the web.
