My website is http://www.AutoInsureUSA.info Do you think, given the niche, I could have any possibiliy of success using Google Adwords? What kind of budget would I need (daily)?
You don't have a chance with that site - not at all. You have basically zero content on there - create landing pages for each ad group, with good quality unique content targeted to each ad group
Thing is, when people are looking for auto insurance companies, why would they want to read all that content. I feel that this site makes it very simple. They go through 2 pages and find all the insurance companies they need; Unless you mean I am lacking content for SEO purposes, then that is a different story.
