I just signed up today and intend to contribute to this community with my insights and knowledge. However, right now I have a daunting problem.
Basically, I work for a car insurance quote comparison website. The website is built dynamically and in the past, the URLs for each page contained the parameters used to build the webpage. Since then we have moved to internal rewrites using mod_rewrite to create clean URLs.
Anyway, the result of having used this URL convention in the past is that there are a lot of natural links in place from partner sites using these dynamically generated URLs and they differ only by one of the URL parameters. I think this may be causing a duplicate content penalty by Yahoo and they will not index or list our website correctly.
To compound things, for a reason we could not avoid we had to switch domains so that our business has now also moved to a different domain. We have put 301 redirects in place to transfer all of the pagerank and redirect users.
While Yahoo hates us Google, on the other hand, has no problems indexing our website correctly and our Google rankings are great. The only pages of my website that appear in the Yahoo index are ones that are framed in by one of our advertisers.
I was hoping somebody here would have some insights into the difference between how Yahoo and Google handle dynamic URLs and 301 redirects and also any other people that have sites that rank well in Google and poorly in Yahoo.
Thanks
