what could be unethical about autotweeting your latest blog post title? or the latest football scores or betting odds?
as long as you’re not spamming on twitter, you can get good traffic. I am getting 8% of my traffic on one of my sports sites w/ twitter just by autotweeting particular “events”.
If you’re not utilising social media, you’re leaving money on the table. And Fwiw, automation is king imo.
