Need advice: How to 'pad' my CPA offers?

Hi BHW

So after trying many different methods since i registered here i have finally found a good method for myself where i can make some decent cash. The problem i am having is i am getting very high conversion rates for 1 of my offers and hardly nothing for the others. I am very worried that my CPA network will think i'm doing something wrong when i'm not and revoke my leads or not payout when the time comes. I am getting 25%+ conversion rate for this offer and it pays out $2.50. Can someone with a bit more experience tell me if this kind of thing is normal or should i try and get it down a bit.

One thing i have done is bought some junk traffic which lowered my CTR considerably but since i get very few clicks it doesn't make much of a difference to my conversion rate. If someone could give me some advice/tips on what i should do please! I really want to scale this method up so i can start earning more but as i said earlier i'm just a little worried that it might all be for nothing if i don't get paid out.

Thanks in advance for the replies!
