How can I make sure affiliates are marketing correctly?

Hi everyone. This is my first post and if you don't mind I will get straight to the point...

My product is just beginning to set fire on ClickBank and I am keen to capitalise on the recent interest that is materialising according to Google Analytics statistics that show an increasing number of referrals from ClickBank affiliates, which I think is great news,

The only thing is that upon further inspection I have found that most are bidding on ineffective very broad PPC terms.

I've been doing a lot of PPC myself to market the various products related to my book, and the e-Book itself. I've discovered that some of the most ovbious keywords are extremely competative and I never got a good return on them because the PPC rate is so high, however...

Other narrowly-focused keywords I've discovered are extremely effective and produce an excellent ROI.

My question is simply - how can I contact the merchants (I have their ClickBank user ID's from the Analytics report) and let them know what they need to change?

PS. Don't tell me I should have collected their email addresses in the first place because affiliates can come straight from ClickBank's "Promote Products" page!

Thank you in advance, and I wish you ALL the best.

 

You shouldn't I think . Some will bid broad , some will bid well and earn better . You will enjoy both , it is not like you will sell more copies if someone -doesn't- bid on broad keywords .
