I will actually tell you the best way to do it. Well if you are using WordPress anyway.
Get yourself a month membership on
@Festinger vault here on the marketplace in bhw.
I'm not a member or in any way affiliated to him by the way I've just seen what he has to offer and it's great, I'll probably join in the future but happy to recommend a good service from a fellow member when it's a good offer.
Download thrive architect and thrive optimize, install both and activate them in wordpress.
Create a new campaign in ogads called test and one in cpabuild or whatever other network you use.
Create 2 identical pages but have one page locked with ogads and another with cpabuild or whoever and split test them with 50/50 traffic.
Then let it run for a month and check the results.
You'll see if there is a problem by the stats of the two.
