It keeps me working 8 days a week. I get several, as in more than 5 calls every single day off of adwords. I had to turn my ads off last week I got so many calls.
I average $2 per click(used to anyway). I stopped my ads for a week, because it got so crazy, I couldn't get any work done I also changed my name and website. Tried to re-post them two days ago, and it seems they have penalized me and started me from scratch. Keywords that I had a 9/10 quality score went down to 4/10. Might have to rethink this. The lower the score, the more it costs and the further down the page the ads go. I still got about 30 calls with no ads running. Enough to keep me busy. Did my first $1000 day yesterday by myself, with no ads running. I might do it again today if I can get out early enough.
