I joined some CPA since last month but I promote only two offers. How many offers do you promote from all your CPA. Do I have to promote more offers in order to make more money ?
Depending on your site I would say promote one offer at a time, although I don't do this I promote a few similar offers on rotation which works good for me.
i promote as many offers per merchant as possible in a given timeframe, i do headline a offer but to get the most from my site and mailing lists i send as many as i can. what i do is put a subid on the links so i can track any sales off a given link.
i have some clear winners but I am always testing new offers and looking for gold! I think thats some affiliates problems they get tunnel vision, then when an offer is starting to get burnt and can't find another way to generate income...
it depends on what type of publisher you are ... if you are search marketer any campaign will work for you who offer good ROI but if you have site on specific niche then usually those kind of offers are preffered
