That's like asking "Does anyone use a car or bicycle for transportation? Is it worth it?" All AdWords users use it for that reason and considering they spend billions, it sure as hell is worth it.
And equally, you wouldn't start an AdWords campaign if you wanted to increase your traffic by 1 unique a month. If that's what you're after, then the answer could be "no" indeed. But most give up before trying properly and it will still get you traffic.
Yeah well obviously, if you set out to reach a stupid goal like gaining 1 unique or traveling 2 metres, nothing is going to be worth the hassle. So that's my point too.
Amitpatel is using adwords for his directory Gii.in I asked him why he used adwords he said me that he had no other option but to go for adwords as he can gain more publicity for his directory!
Well, the beauty with adwords... it's not only for traffic. Lots of people parse the data, and put real SE-Findable text/links into their sites... which means true backlinks
Timely question for me, I've just started using it for LinkLister and with limited £ resources I've received submissions each day which I'm guessing come from the ads due to the quality of the links. Is there a mod to ask submitters where they heard about the directory? This could be really useful.
I use it for 4 for days. You get more traffic for sure, but not more submission I will keep use it for a while though.
