I have a website that has over 5000 links generated on the sitemap. Half are products and the other half are images. Effectively there is one image per product code.
The search engines are ignoring almost all of these links and just indexing 70 pages.
Where can I find some good guidelines on how the search engines operate. When I posted a message on google all I received was a comment 'how many pages do you expect to be indexed!'
