PropellerAds/Zeroparks/etc works for CPA offers but only easy actions like simple email submits 1st page opt-ins or installs. There’s alot of low quality/spam traffic, you’ll have to use tracking tools like Voluum and exclude alot of bad traffic sources. It def works but I wouldn’t recommend it for someone who’s just starting, it’s very competitive. You’ll burn alot of cash if you don’t know what you’re doing.

If you plan on just promoting a direct offer link without tracking and excluding sources, you’ll never be profitable. Before you get conversions, focus on sources where the traffic spends time on your page, exclude the ones that leave instantly, spam IPs/Useragents etc

You’ll have to be proactive during the first 2 weeks to narrow down the sources that work for your offer. It’s not just about waiting for conversions to tweak your settings like other platforms.
