Today we received messages in our webmaster tools account, for all but 1 of our 20 domains, indicating that Google considers them doorway pages. We have also lost all of our SERP's for those sites.
Each of these sites is unique in the sense that they cater to specific categories of sporting goods, however they do have product crossover (some sites more than others) and the structure of the pages are very similar. As an example, [one] site sells only snowboard gear, but many of those products are also on our our general sporting goods store, which is also the one that did not get dinged. Each site has it's own cart and checkout and we do not push users from one site to another. We also do not use any 301\302 redirects across domains. We have been operating like this for many years without incident until now.
Our questions are, why has Google dinged us for doorway pages and what is the best (and fastest) way to fix this problem.
We are considering trying to change the pages on each site to make them more unique or possibly using cross domain canonicals. Can some please advise?
