Hi there, Lenny2:
i will throw these ideas out there and hopefully someone with more experience than I can either confirm or deny the following (or at least they will spark an idea for you):
2. Anything one would do to optimize a single page... versus an entire site...
I got some links to my INTERNAL pages where the anchor text was just the root domain. some were "www.mydomain.com" and some were just "mydomain.com"
4. Rotating product feed which updates with new fresh products every time the page is loaded... including snippets of content about the product.
i would love to know what others think about this. To me, it seems like it might be counter productive.
I am purely guessing here, but I would imagine that google would like to see SOME consistency. Also, I have had people mention to me that linking directly to PRODUCTS might not be as helpful as linking directly to CATEGORY level pages.
I am not sure 100% why, but I am guessing that google still bases a lot of it's understanding of the home page of a site depending on the linking structure of the home page. (Again, I am hoping that someone with a better understanding of this will weigh in and help out.)
My view might be tainted though. i have gone to sites and seen a product listed on the home page. Then when I went back later, the product was gone, and I had a hard time finding it again. For what it's worth.
One question for you:
Have you closely examined your crawling logs?
someone mentioned to me a technical error, where they had incorrectly coded an absolute URL to their home page. they forgot to include the http:// in the absolute URL, and so their link looked like this:
href="www.mydomain.com/"
So the final link when it was displayed (or followed) was this:
http://www.mydomain.com/www.mydomain.com/
They said that not too long after fixing the problem, their rankings started to regain.
MUSING OUT LOUD: Panda must be so complex, that MAYBE many technical errors that wouldn't have consequences in the normal algo are causing problems for Panda?
