Hmm a couple of thoughts here:
Yeah you're right to be concerned about overlap. If you duplicate the adset and target the exact same 'action figure' interest, your ads will essentially compete against each other in the auction. This often drives your costs up for no good reason.
A much better way to do this is to test the new product inside your existing winning ad set.
So, don't duplicate the ad set. Just go into the ad set that's already doing well and simply create a new ad with the photos and copy for your new product. Let both ads run in there together.
This way you're letting Facebook's algorithm do the work. It'll test both ads with the audience and over time it'll figure out which one gets better results, then automatically shift more of the budget to the winning ad. It's a proper creative split test and the best way to introduce new products without messing up a campaign that's working.
Hope this helps!
Don't duplicate the ad set, you'll just make your ads compete against each other which drives up costs.
Just add the new product as a new ad inside your current successful ad set. Facebook will then test it against your existing ad and show the winner more often. Much more efficient.
Hope that helps!
Some thoughts:
Good question. Duplicating the ad set to target the same audience is generally not the way to go. You'll definitely see overlap and your ads will start competing against each other, which usually just makes things more expensive.
What you should do is add the new product as a new ad within the same ad set that's already performing for you. This is basically how you do proper creative testing. You're telling the algorithm "here's two different ads for the same audience, find out which one they prefer". It'll then optimise the budget towards the one that performs better.
Hope this helps
