I hope this is the correct place to post this. If I am wrong please let me know....
I have a problem I could use some advice on.
My site as been on the net for over 8 years. Last year we incorporated an article directory on the site. While it works for searches and gives us broad range of terms listed in the search engines for our niche it has also caused problems.
Our rankings for the main site (products) have started to slip. Our PR also dropped. I am thinking it's because of the additional pages of (over 5000) articles this year have really watered down the site. What I mean by that is all the additional content has made our relevancy slip.
We used to have a strong PR across the site when we had about 30-40 pages and also enjoyed high rankings for those pages. I think it's a case of too much too fast.
Does anyone have any ideas how to fix this? I would dump the article directory but our visitors love it since it's exactly what they are looking for plus it gives us more search terms.
Maybe use no follow links on the articles to stop bleeding PR?
Someone also said that article directories are registered differently or maybe seen differently by Google. Is this true? Has anyone ever heard this?
I am just looking for some opinions on the next step to take without making matters worse.
