Is this good for SEO? I see some sites doing it, I find their results on Google and click on them, do they do work right?
Given a site search, someone searches for:
The search is processed on the URL
The results are returned, nice meta tags/titles generated, etc. The search can then appear on a list of 'popular searches' on some page on the site. These can be manually filtered to prevent spammers gaining entries on the list.
Is this worth doing? Good to get more visitors from engines? Is it useful for them?
