I have a question about Yahoo search results. What could cause a search for "site:www.yourdomain.com" return your homepage then all the inside pages that are listed have lower case type titles and no description. Also none of the pages are Cached. I am asking because I get good search results in Yahoo, but feel I could do better if the interior pages were not the way the are. I think the site was penalized at one time because I was out of search for 2-3 months. I made a few changes and emailed them to review the site then 2 weeks later I popped back in. I have been raising in the SERPs since then, but have been waiting for them to pick up the interior pages, but thus far no luck. Any ideas?
Please give the actual example of your site to demostrate what is happening. Not clear what you want.
Hard to say what is happening without seeing the site, but I have experienced strange fluctuations in the number of internal pages that yahoo indexes in the past. They always have some internal pages indexed, but sometimes they will suddenly drop half of the site and then it will eventually come back. I don't have a good explanation for this behavior.
