How can you use PR to boost site search rank?

Make sure you list your site with associations and directories because part of Google’s site rank formula is the number and importance of inbound links.

Make sure all Press Releases are optimized for SEO (Search Engine Optimization). Insert an anchor text link to the site as often as possible.

Deploy as many web videos as possible. These get indexed in Google’s Universal Search results and can boost site rank as well.
