A bit of cross-linking
Once you have more than one web site, you can use them to help each other. While most SEO agree that reciprocal links carry less weight (=bring less benefit) than one-way inbound links, they can at least help you to get noticed by the search engines faster.
Interestingly enough outbound links also help. Not as much, but a little. Of course it always depends on what type of site you’re linking to. ‘Authority sites’ are the ones which help the most.
I like also pointing to the search results of an authority site, which lists other sites of mine. This can potentially help in two ways: 1) I am linking to an authority site. 2) The result page of the authority site has a link to me (the search result). Once this trick becomes more popular, the big search engines will put a stop to this, but for now it seems to work :-)
