If you're getting lots of referrals in your logs on your company name then it suggests that people are able to find it ok and you probably don't need to pay to be found.
Good point Karmatar. I shoulda thought that one out more logically. Our URL comes up first under our company name search and there are no PPC ads. Guess I got a little nervous when I read that advice.
I agree that Karmatar has an excellent point. On the other hand, if you're still curious as to what might happen, then you can always find out for a really minimal investment in time and funds. ;)
(I talked to an advertiser, a while ago, who had a $0.15 daily budget, and was really tickled by the increase in traffic they had seen. So it's possible to experiment for not a lot of money.)

If your site is called perfectwidgets.com you bet alot of users will look for "perfect widgets" and your site will not show up (unless you covered this with adwords).
