Does anybody use these services or advertise on the web? What kind of results do you receive and what is the best route for return? Does it even work?
I use AdWords and it works just fine. A couple more forums to read on the subject (friendly to newbies): The Link The Link
I have a couple of friends who own companies that perform website optimization. A big part of how successful it will be is determined by how "search" friendly your website is. I know that my company's website is always ranked near the top of google due to our adwords campaigns, etc. If you're interested in more information, I can put you in touch with them. Send me a PM.
