Im looking for a cpm type of ad, which one pays the most?.--Answer1:No, you should do your own marketing. Target the type of person that would visit your site or pay for whatever you got. I am into marketing myself and find out that Googles "super formula" to get listed is extreme with even big companies not even listed in top rankings. Building your site properly is important though for maybe more chances to access your site by a search engine. I advise going to forums, myspace, do direct mailings with postcards, or do email marketing but make it good, not spam. Link with other sites that are similar by banner exchange. I dont think people really read the ads that are cluttered online or in papers that much. You gonna have to contact groups that are interested in your product. Make sure you tell people what the benefit of your site and be attractive when telling them the difference with the competition. Try yahoo groups, myspace groups, and major social networking groups similar. You can send a message to hundreds even thousands of people at one time. Use google webmaster tools for free statistics. Keep marketing, give benefit to customers, and looking good... youll succeed. Hope this helps, good luck!.--Answer2:Free Viral Advertising!Go here and try viral advertising - it works!
