Hey guys what Facebook ad objective are you using for your teespring campaigns?

I'm currently running one PPE and one website for conversion.

Now the one optimized for engagement gets great engagement. And it's costing me 0.04 an engagement in major countries. But the url link is not getting clicked Often. It's got a few sales but no more. People like and comment and tag their friends in the post but aren't coming through to the sales page. It's just a regular post. Should I be doing something different?

I just started running conversions for website and not too sure about this objective with teespring. Never used it belong getting leads. What should i be doing to optimise and tweak this campaign.

My reach is 18,000,000 I've only spent $1.15 for a reach of 635 in the past 5 hours. Daily limit is $5. Should I up the daily limit?

Anything else besides testing different images and copy?
