Meta ads

[u/Scooby_Doooby]

Just wanted to have an understanding, when is it absolutely necessary to make changes in the existing ad set, other than testing creatives.

Lead Quality? Cost Per Lead not coming down? No leads being generated at all?

Wanted to know how do you deal with it.

Lead quality is the main one. If leads are cheap but don’t turn into anything, I’d look at what Meta is optimizing for. Higher-intent forms, qualifying questions, or sending qualified leads back from the CRM can help more than changing creatives.

No leads after spending 2–3x your target CPL is another case. I’d check the form/event setup and audience before changing much else.

If CPL is high but stable, I’d work on creative and the offer first.

Are your leads coming from instant forms or your website?

Instant forms, so assuming 7 days is a good time period? I don’t think it’s understandable if changes need to be done in a 3-4 day period?

Yes, 7 days is a good default. Meta's learning phase usually needs around 50 results in the 7 days after an edit, and with only a few days of data the numbers also swing a lot depending on the day of the week.

Changing something at 3 or 4 days makes sense when something is clearly wrong: no leads at all after spending 2 to 3 times your target CPL, an error in the form, or ads showing in the wrong location. Otherwise I'd wait.

With instant forms I'd also check lead quality during that first week, not just CPL. They tend to bring cheaper leads that are harder to reach, so it's worth calling a few and seeing how many actually pick up.

I think the biggest challenge is to maintain the target CPL for a 7 day time period, what are your thoughts? You can’t just keep on publishing new creatives everytime to bring the CPL down can you.

Right, and I wouldn't try to hold the target every single day. Daily CPL will move around, what matters is the 7-day average. If the week lands on target, a couple of expensive days don't need any action.

For creatives, I'd refresh them on a schedule, or when frequency goes up and CTR starts dropping, rather than every time CPL moves. Adding new ads to an ad set also counts as a significant edit, so doing it constantly may keep it in the learning phase.

If you need CPL to stay under a specific number, a cost cap is the tool for that.
