I've been doing some in-depth looking at my competitors and it seems on many good longtail keyword phrases, such as specific product names, etc.., deeplinking is the most common pattern. Most of the top pages on the Google return had many links pointing to them from inside their own site. Yet Many only have several backlinks. On the long tail phrases I am on top of I have the most inner linking. So in theory I should be able to take some not too sought after video games and by linking to them from several pages, I should gain in, or place first for the serps. At least over a given number of products many should gain in popularity. My question is, Would displaying random links on every page have an effect? Or would the links have to be static to give juice? So if I have links 1, 2, and 3, On any given page, can I randomly select one of these links to display, and after a given amount of time, will all links be counted to some extent in the eyes of Google? I have often seen the same page displayed in different locations on a search after an edit.
I think I have figured a solution for static linking, for products under PC games - action, page 1 will have links to pages 2,3, and 4. Pages 2 will have links to pages 3,4, and 5. Page 3 has links to 4, 5, and 6. And repeated for the entire sub category. Of course I would be linking to more than just 3 other products. Perhaps 8 per page. I would just have to deal with the first 7 products as far as them not having an equal amount of inner links to them. I guess it's the same as cross selling to a customer, only it's Google and they don't care if they see the top ten or not.
