Hey Gadi, 

This is a trend for a while now. Some traffic campaigns still perform well, and if your budget is very low it's all you can do. However, the algorithm is so powerful that if you stumble upon an ad that gets clicks for reasons different from the real pull of the offer, then you can end up with a campaign that performs terribly, simply because Facebook is honing in on those people that are clicking, rather than those that want the music. If what you want is conversions it is ALWAYS better to choose conversions as the objective, unless you simply can't afford a big enough budget to get you at least 5 leads per day.

It's also a good idea to leave expand audience unticked.

I wouldn't say it's the only way. But with this particular ad copy, image, and audience, it seems like it might be the only way. But f you change up the ad, then different people will click and things could work. But going with conversions is a much better approach.

Hi Gad,

I do sometimes see discrepancies like that. The blame can fall on either platform. Aweber's stats are pretty reliable in my experience, but things like double submissions can through the numbers off. Facebook can miss conversions if someone is using a blocker that prevents Facebook from recording the conversion, or if someone converts days after being exposed to the ad, and the data has already been wiped or they ultimately convert from a different device than that which they used when they first saw the ad.

What is most important is that you look at how many subscribers actually came in, and how much you paid. I do occasional manual calculations like that just to get a ballpark idea of the drift and then just mentally apply the discrepancy, if needed. But for the most part I normally see conversion tracking to be pretty close to accurate over time.

If you ever see something different, where Aweber is reporting one number and the number of subs you have doesn't line up, then I would contact them to ask why.
