My ad was a thumbnail pic of myself and the text read something like: "My name is Tomas. I've spent the past two years perfecting a new design of RFID-blocking front pocket wallets to give you an alternative to your bulky billfold. Sitting on your wallet squeezes your nerves and creates an imbalance in your foundation. Sign up now for early notification when I launch". Which led to around 70 clicks over 3 days with 1 day left and I spent $20 out of $30 total.
Have you used Reddit ads? What are some of the best practices you found in doing so?
My best advice after using it once is that the subreddit you choose will affect conversion rates a lot. Other than that I think it was a pretty good and cheap way to get the word out which led to a few conversions with a small budget.
