I've been running some Twitter Ads, and based on how pathetic the conversions are, I'm thinking it's mainly bot traffic I'm getting. Not suggesting Twitter is running a botnet, but the platform is probably so overrun by them that I'm paying for garbage traffic. I had very tight targeting and was only going for tier 1 countries and the conversions were horrendous.
I just don't see it as a terribly effective platform, even for ad dollars. It's probably great if you only want to build brand awareness because the impressions, engagement, and clicks are comparatively cheap, but I'm not sure I'll stick with the platform for conversions. I'm going to test a few more offers, and some lead magnets to see if I can get anything to stick, but overall it's bad.
Sadly, I didn't expect it to be this bad. I bought traffic to a Shareasale offer so I have little visibility into the analytics to determine the traffic quality (time on page, pages per session, bounce, etc). That was my fault though. The next few tests I run will be to properties where I have analytics access.
