I'm starting this thread in hope that we can make a large list of negative keywords to use with Adwords campaigns.

Let's start:

-free
-info
-help
-trial
-complimentary
-sample
-freebie
-image
-torrent
-blog

What do you mean by negative keywords?

Keywords that you shouldn't include in your campaigns? Never pick words that aren't targeted, I've learnt personally, phrases like 'make money' do not work with PPC as they do not target the right people, they target people who are just browsing for information. Any keyword that isn't targeted is negative, as you will end up getting clicks from people who are not interested in what is on your page.

Yes, that's true but you MUST have some negative keywords. Some cases require it!

MMTV: by negative keywords I mean keywords that shouldn't be associated with your ads.

Here are a few more i've recently used:

-cheat
-free full version
-registration key
-serial
-crack
-warez
-torrent
-cheat code
-trainer
-keygen
-activation code
-free key registration
-download full version

i am not aware of this concept. Anyhow understood from what you told. Thanks for the info.
