Question

Hi guy's recently start a new CBO for a daily budget of $35 and 7 ad sets + 7 interests in each ad set $5 each ad set. Few questions. 1. How long should I keep them going for? 2. How to tell which one is performing better then the other? 3. Can I swap in other ad sets if one ad set isn't working well? Thanks in advance.  

Answer 1

Can't give you concrete answers unless you give more details mate. 1. What are you trying to achieve? Prospecting? Creative/copy/audience testing? 2. Your budget is a little low for CBO. Thankspically you would want to set a minimum spend of 1/2 your adset Budget if you are doing CBO. This way Facebook is forced to spend some money to give you some data - generally used in audience/Creative/copy testing. 3. If you swap in other adsets into your CBO, the other adsets will NOT reenter the learning phase - this is clearly listed in Facebook's business help Center or blueprint. You should take a look there

@efrem340 I am trying to test interests. I had a recent fb ad that wasn't CBO and was normal abo but it has 12 interests narrowed to 7 but I wanted to try cbo to test different ad sets. So I should just reset and do abo for the 7 ad sets instead on 1 campaign?

@wail18056 If you are willing to raise your testing budget to at least $20 per adset, then CBO is the way to go. Otherwise, go "old school" and test using ABO. I'm sure there will be people that argue that $5/adset is enough for CBO, but I really don't recommend it. For testing purposes, test for at least 3 days or until your target impressions (or whatever metrics you want to test) are met.

@efrem340 ok so old school for 7 ad sets on abo for $5 per ad set on 1 campaign

@wail18056 If you are really restricted by budget then yeah $5. If not, even with ABO I would recommend going above $10/adset. Do note that testing using ABO isn't nearly as cost-effective as using CBO, but you tend to get away with using lower budgets IF you know what metrics you are looking for to determine success/failure of the test.

@efrem340 well I am targeting jewellery. So even if I get ATC or purchase is better compared to others even lower cpm on ctr.  

Answer 2

I agree with @efrem340. First of all, what is your goal? If you try to achieve sales, $5 per ad set seems a bit low. If you want to test things it's better to start with ABO campaign;)

@wail18056 do you have proven concept that works in that CBO campaign?

@cote400 Nope I am testing cbo at the moment.
