My case is like this:
In a product page there is related products section and we pick products from same category. Simple SQL query , no magic magic
Is it any better to execute similar documents query on full text search instead of this? for both user and SEO? eg: lucene/solr or db full text index
it would be like wordpress related post plugin http://wordpress.org/extend/plugins/yet-another-related-posts-plugin/ this way related products will contain more common keywords than current product list.
I wonder any usage of this kind of related content in a detail page is helpful for SEO? I don't need it for users , but is it worth to do for search engines ?
Thanks in advance.
