What are the best ways to increase a site's position in Google?
I have two sites that I both control and have hooked up to Google Webmaster Tools as different sites. My problem is that one of the sites (Site A) was created as a preparation for the other site (Site B).
Although I want Site A to still exist (even on Google), I would like to have Site B score better in search engines.
Is there anything I can do implicit or explicit to make Google (and preferable also other search engine) prefer Site B's content over Site A's?
