Google is constantly reindexing the web. Active portions of the web may be visited several times a day. Less active portions may be spidered once or twice a month or so.

Earlier this year they appeared to have created a filter on new links / new sites to where it takes a while for your rankings to really go up in competitive markets (especially if your site is new and does not have much linkage data pointing at it yet)… it will typically take 90 days for most people to start seeing decent movement in Google in competitive markets.

Don’t forget to mix up your link text using various different descriptive link text combinations when you get your inbound links. Some directories will only let you use your official site name and some are a bit more lenient.

Also keep in mind some of the other things you can be doing to boost your site: writing articles, participating in communities, logical link swaps, asking for links, etc.

Best of luck with your site!
