The first thing people want to know when they hit on a winning campaign is ‘what's next?'. Lets cut to the chase and talk about some ways you can scale.
Ask for a payout bump
This has got to be the easiest, and kind of surprisingly overlooked, ways to scale a campaign. Any payout increase will help. So how do you go about getting a pay bump? Usually the network will want to see some traffic and gauge the quality a little. Sometimes they will bump you right away (usually when they were offering a low payout to being with).
Talk with your AM and see what they can do..even a small payout bump can take a campaign to the next level.
Rotate offers between CPA networks
This seems like a weird one to some people, but the same offer can convert very differently on different networks. The reasons why could take a whole post, but for the sake of scaling I would highly recommend split testing the offer you're running with a few networks.
Bid into a lower position
This might seem the opposite of what you would expect, but being in a lower position can increase your ROI quite a bit. Have you ever seen those insane bid differences between 1st and 2nd position? Let those idiots auto bid each other into the red, while you sit back and pay a ton less (leading to much higher ROI in some cases)
Duplicate your campaing on another traffic source
Got a winner on Traffic Vance? Why not run it on Lead Impact and other PPV networks too. Since the campaign is already built, it really only takes a few minutes to copy it over. I've had campaigns where just doing this literally doubled the net profit.
There's no reason you can't run your campaign on a totally different traffic source too. It will take a little adapting, but if you know an offer is converting there is a good chance you can make it work somewhere else.
Bid on target variations
Most people bid on domain.com but there are a ton of variations that get traffic and often have less competition.
You can use some variations like
.target.com
target
/target.com
etc
some variations work better on certain ppv networks.
Figure out why that target converted
Say you are bidding on a target that's producing a great ROI; see if you can figure out why it's performing so well. Does a certain demographic visit that site? Is it in a certain niche? Are the visitors of that site looking for something there that makes your offer really appealing? The cool thing about doing this is there is really no tool to do this other than your brain. If you can master this, you'll be far ahead of other ppv affiliates.
So there you have it. Even if you have a campaign doing just a few dollars a day, applying some or all of these techniques will absolutely squeeze more money out of it.

Great tip about bidding into a lower position.
Let the idiots fight over the 1st position and throw ridiculous money at it. Grab the 2nd or 3rd and enjoy just as great ROI.
Yeah, it’s amazing the prices some people jack these bids up to. Especially when there’s great ROI to be had at lower positions.
Great post.. but please enlighten me on how rotating offers between CPA networks can help? I know you said it would take a while post… but even just a few bullet points to give an idea would be much appreciated 🙂

One thing would be redirect speeds. Brokered offers have to go through more redirects and it can have a surprising effect on your conversions.
Like it! I couldn’t agree more being in 2nd will in almost all cases make your ROI increase.
We also ran our CPA offers between several different Networks, it is similar to A/B testing on site design.
1. Every network has access to certain pubs and different types of consumers, by testing two or three different networks we found that one vertical (weight loss) worked better in network A and a different vertical (biz-op) had higher conversions in network B.
