This morning, DayTradingRobot Sent me an email for promoting its' product, i check it, it seems that it is very hot in the "Money & Employment" market. If i use PPC to promote it, there must be tons of competitors with this topic, and it will burn a lot of money, how to do it?
if you're doing ppc ... search for good long tail keywords that other people have looked over and use them ... if you're doing seo/organic ... search for good long tail keywords that other people have looked over and use them
Also, try adding words like "buy" and "download" in front of the product. Usually, people that search this are already ready to buy, so you're just providing the link to the site.
