cloned ads dont go through approval process

I've noticed that if you have an ad already approved and running in your campaign and you go to 'create similar ad' and don't change the ad copy, the ad has an automatic approval.

I'm not sure about the internal workings of the fb engine, but at first glance this looks like it could be a way to maximize your exposure & tracking. You can clone ads really fast and change the targeting to see which demographic performs best.

I'm hoping that cloning and ad means you will get double the imps, but I doubt fb is that dumb. any thoughts?

Sadly, Facebook isn't that dumb and you have some mistakes regarding Facebook ad approval.

While that might be true the duplicated ads get approved faster (don't know, didn't check), what is completely certain is the moment you edit an ad to change the targeting it goes under review again.

Cloning an ad just to change the targeting later doesn't do any good.
There are a lot of ads that get approved immediately (sadly people only talk about the ones that don't), using this trick might feel like you're fooling the system, but you don't - You're fooling yourself.

About cloning ads for double exposure, sure that might sound like a reasonable enough theory, but in the real world is isn't the case. I've ad many ads duplicated (since they were working so good) but sometimes the ads act completely different, sometimes they don't work at all. Point is, there are a lot of good reasons to duplicate ads, but double exposure isn't one of them, raising bids or budgets will work better.
