You have to have site that is popular in order to get hits. Take myspace for example it very popular among kids thus the word of mouth advertisement is used. This I think is the best way to increase traffic. The second best option is to go around and post your website into all the search engine databases you can find. Also you might want to try Googles adsense program which can get you some money also. Most big search engines like Yahoo! or Google will let you also put a ad on their results page. Linking with othersites is really not that great. If you are using that as your main source of getting people to come I don’t see how you got 200 700 daily comming.
