ESL go.com's speaking activities used to have a page rank of 4 and was number 5 in Yahoo and Google search results. Now it's number 12 in Google and 10 in Yahoo, so I checked the page rank. My Google task bar says the page is not ranked. I didn't do anything to get it unranked, so I keep wondering if a competitor can somehow hurt my page rank. For example, you know those rumors about how submitting to FFA link pages can hurt your page rank? If that's true, your competitors can sign up your site for all those nasty FFA sites (thereby hurting your page rank). That's why I hope it's not true that a link from a FFA page to your site hurts the site's page rank.
