Adwords are a compete waste of money IMO I've tried it with several products that i sold via an affilate program and had no luck. You really need to know what your doing and can be costly quickly! I've never tried it with my carpet cleaning business but from what i have heard from other local businessmen and woman it sucks for them too..
Organic listing and local buisiness listing are the vital ones. ( the ones that appear next to the map) Alot of people are getting "ads sponsored by google" blind and wont bother clicking on them and would rather check out the proper listings, thats what i have found from my experances and testing.
And on a darker note, there are loads of competitors that will constantly click on your ads (costing you money!!) get their friends to click OR use a proxie server (alot easier than it sounds), constantly changing thier IP address , then click on your ads (google wont be able to detect click fraud that way....
But dont let that put you off Jason, go a head and try it. Like Derek said, its easy to set up and monitor. Here's the link
http://www.google.co.uk/intl/en/ads/ then click on Adwords on the left of the screen.
The offer of a seo'd, feeder site is still there too....
Good posts by Ian and Garry! Like Garry said, I dont want to give out my niches, keywords and way of working away! Took me a LONG time to achive what i have.. As tempting as it is Mike

lol
Weldone, you caught me lol If i wasn't working today and seen Mikes post earlier i'd of happly shared my carpet cleaning site. Like Bob said, not exactly Taggert legue detective work! lol
My site is pretty pish if i am honest, its built purely for seo and its dated! Its 5 years old, been modified twice in that time! I have a list of things that i want changed/added/taken away!! but just not had the time in the last few months to get round to it.
Westy, i did build it! do you think i would of paid for that! lol The chap that owns the hosting/design company (Paul) is a good friend of mine, and when he started up a couple of years ago i was his first hosting clients plus i gave him a link on my site as it had a PR4 at the time (now a pr3) to boost his link juice. My site is 5 years old, and the link has only been there 2ish years.
