no it doesn't, and you can get some pretty cheap clicks using a technique. I have been able to get some $.03 clicks on some pretty expensive pet related keywords. Here's how it works. I create an image ad for all 8 sizes google uses. I create several adgroups with 2000 keywords each(the max) each using the same image ads and absolutely no text ads. I set my default click at $.03. Nothing is enabled for search due to my low bid, but after a day or 2, my ads started to get served on the content network, then after I got a click, they started to get served even more. I've been getting my ads served for 5 days, and have got 4 clicks for .$12 using 14,000 keywords. If I tweaked my ad and increased the keywords, I bet I could snowball into some serious traffic for cheap! I get the keywords by using the massive keyword list builder. I give it a seed, then it generates a list of 10 to 100,000 keywords for me, although it kind of gets off topic past 500 keywords, so you have to have a decent list of root keywords to use. qustions?
