Sitematch: Organic Rankings Suicide?
Tim Mayer clears up some issues concerning the Site Match PFI system. Many webmasters are confused by Site Match and theories that once your budget runs out or you stop using the service your organic rankings drop abound on the SEO forum circuit. He had this to say in the post threadlinked above:
We made a slight change a while back as we have been really focused on comprehensiveness at Yahoo. If we dont know about your site and you submit it to Site Match you will be suggested for inclusion in the main crawl and go through all the usual quality determinations to figure out if and to what representation you will appear in the main crawl index. The conspiracy theories that we will knock the rest of your site out of the index or that we will delete it if you dont pay are just not true and if anyone experiences this they should send me a message via forum mail documenting this. The issue is usually a content issue and people usually try to blame Site Match for their problems.
