I tried this out a few months ago. Spent 20$ for a month of ads, it did fairly well. I used it on my game site and could see the traffic from it.
I might do this again for the game site if I ever get another 20 in paypal that I can spend on that site.. I plan to spend some money and run some ad's for about 6 months when I get this site closer to being finished.

has anyone had any success with adwords ?

I've never tried it. I'll have to have a peek

I was reading that their prices have gone up
I was a little nervous that who time, afraid it would get a way from me and I'd end up spending a 100$
next time ( if I try it ) I'm going to read everything b4 I try it

I was on one submission site last night (this morning, around 3-ish or so, lol). They have different search engine submission packages, and the price depends on how many urls you're submitting.
Like if I want to submit only one of my urls, it would cost me $3.95 per month, they submit it to 100 search engines, monthly, meaning every month, and bill me for it. I would received an email confirmation from each one of the SE's so I'd know it was done.

Sounds like a pretty good deal to me.

no,, don't do that.. I'll upload something for you to play with.. and send you a pm,, one min
