Thanks for sharing the stats on your end. Advertising as a whole is a test and check game. You test different placements, find what works, and continue on that path. We have many advertisers very happy with their sponsored tweets through BSA.
If you're interested we could help make recommendations of accounts that may have a more relevant audience. Let me know if there is anything else we can help with. Send us an email at [email protected] if you'd like to discuss further.
