What is the correct way to cut placements and bids? (3)
I'm a newbie in the first days of campaigns.
For example, I see which carriers and performing better, and see some website ID's that are just plain awful with a decent amount of spend at -100% ROI. Is it ok practice to "exclude" worse carriers and website ID's mid campaign and change bid acccordingly?
Or is it typical to let the campaign run, and then split test on different things?
Confused at this point 
I just posted this thread, detailing one of my methods so you might find it useful, check it out : http://stmforum.com/forum/showthread...146#post279146
Hi tpm767!
How are you?
Indeed, if some sites have a ROI -100% it can be the right time to cut them. However, if it has only one conversion with this ROI and it didn’t spend a lot, it’s better to test it more.
Trust me: you shouldn't cut everything at the same time. For instance, if you cut sites that are draining a significant part of the costs, the rest of the variables (carriers, devices, categories, etc.) will most likely improve. This means that - maybe - a carrier will improve as well, eventually becoming positive.
Another thing: even though a carrier is negative on a campaign and nothing seems to change that, don't just cut it. What to do? Try creating a whole new campaign just for this specific carrier. In fact, there may be certain sites, devices etc. that make the carrier bad, or maybe the competition is higher and you pay'll too much. Eventually, it will bring you profit which you could lose if you simply choose to cut that carrier. The same holds true for sites or devices that have a significant number of conversions.
Wanna ask more questions? Go for it!
Good luck!
Cheers!
