To know how your different ads compare with each other, A/B testing is a must.
So some questions that arise are how many texts and creatives should you be comparing when conducting a test?
There are no set number about how many creatives or variations of texts one should have but three to four work pretty well.
You do not want too many because then the ads become hard to track and compare the different ads but you want just enough to get you quality results. You also need to try out each creative with each of the different text variations. So you are already doubling the amount of ads you are running for the test.
As you get more results in you can compare each of the different campaigns by looking at the "Campaigns page" and looking at the campaign split.
