How do i gain google page rank ( become higher in search engines) and does doing some directory submissions help at at all? Sorry if theese questions may sound a little dumb.
Submit your site to directories and search engines. Add your url to forums signatures and trade links with sites that are same topic as yours.
directories are cool; but writing articles and submitting to article directory is also good idea; specially if you could write good.
If you have some budget to spend, you can buy some relevant paid links at B/S/T (Link Sale) section here at DP. They are proven easiest method to gain PR.
Build as much backlinks as possible. Directory submissions, article submissions, social bookmarking, everything helps. Buying text links / sponsored reviews on related authority sites is the best method.
