Hi. You are right, content is one of the main ways to get traffic to any site. Also don't forget that you also must have links too. The links don't have to be of the same product as most guru's will tell you, so don't worry about that. But do try to trade links with somebody. The spyders will be judging you on that also..
Most folks that have been marketing for a while on the web usually just write their own content pages..However, if you are like me,(lazy) or just not good with coming up with good content pages, then I would suggest using a software program that will do it for you..There are several good one on the market, you can probably find them on ebay pretty cheap, if not for free.
I personally use 'Instant Article Wizard' to build content pages. All you basically have to do is type in a 'subject', lets say for instant, 'cell phones'. Then click search and it will go out on the web and gather tons of info on cell phones and put it into a format. Then all you have to do is select the sentences from the appropiate catagories and sub catagories and quickly build a content page or an article or ebook, whatever your project is...It's superfast..and only takes a few minutes...
Just look around and find the software program that you like best and give it a try..
