For example if you are using DELL affiliate program and then use adwords for your direct affiliate link which goes to dell.com. Isn't that a sure way to make fast/small revenue
Some programs don't allow direct linking and/or using their url as the display url for obvious reasons. Even so, I still find preselling them converts better than shooting them str8 to the destination.
yes but in adwords u can change the way ppeople see the url and direct linking means adwords/email/bots etc?
If the Display URL doesn't match the final destination URL, then the adwords bot or the human reviewers will eventually catch it (sometimes they don't though).
