Be on Google
It may sound foolish and obvious, but being on Google with a good ranking really makes some difference. People that doesn’t know you will search on Google for topics you may be dealing with: therefore, making sure that all your pages are searchable from Google is a good place to start.
As you know, Google among the other algorithms relies on PageRank, which is a system used to rank sites accordingly to the in-links they have: the more links you got from other sites to yours, the better you will be placed in the search results.
Therefore exchanging links with others and promoting yourself through blog directories will help you not only in being reached through this links, but will also help in being found through Google, since you will gather more and more importance.
Cooperation with others becomes a must.
