Affiliate Marketing Secrets

I am conducting some market research to help with the content on my website – www.genuinefreebies.co.uk.
I own an affiliate marketing company and I focus on providing hints and tips through my blog for people to receive ‘free gifts’ (such as Xbox, PS3 and iPads) through a referral based system.
Now, whenever you see adverts or google links saying ‘Free gifts’ or ‘How to get a free iPhone’, etc – do you ever click it? If so, are you skeptical?
Hopefully with the information I gather here, I can tailor my adverts and links to stop being perceived as ‘spam’.
Thanks for your help 🙂
