From my observations I believe that your bounce rate and the amount of time the visitor spends on your website are becoming two of the biggest factors in your search engine rankings, especially in Google. I wanted to start a thread here to drum up some conversation on ways that, as blackhat SEOer's, we can some how manipulate the bounce rate and time on site. I think that if we can figure out a clever way to lower the bounce rate and increase the time the user stays on the website then we can dramatically increase our search engine rankings. I'm not looking for answers like "provide useful content" or "put a video on your landing page", but rather I am looking for blackhat solutions. Is there anything we can do with opening new windows, iframes, redirects, etc. that would trick the search engines into thinking our bounce rate and time on site are better than they actually are. Hopefully we can start some good discussion as I think it is a worth while topic and I believe that more and more the search engines algorithms are going to be adjusted to add more weight to these two statistics.
