One of my info sites has a structure like this:
Product page -> gallery page -> one image per page (many such pages).
Each image has a short description and a Adsense unit.
The problem is that those (many) image seems to create big problems for my site with Panda and situation is getting worse since Panda 4.0.
I see traffic decrease each day for image galleries.
One solution is to use lightbox, but there is a catch, a big one: adsense does not run inside lighbox (the code is not loading), so I lose 25% of the total page views of the site!
What to do?
1. Actual situation: steady decrease in traffic and revenue = slow death in max one year.
The actual implementation = a lot of page views, a lot of page/visit, but low time on page, especially on the article page.
2. Risk to implement lightbox, lose 25% revenue, increase time on article page, redirect 301 from gallery pages to the article page => concentrate the focus on the article (content) page and hope for a miracle.
