I do believe the heart/favourite games DO NOT work at all as they are too easy of a way to try and fool Etsy's algorythm. Artificial hearts do not boost the shops at all. However, what we can do is post our pages and check out the 5 on top of ours earnestly, and only favorite them if they GENUINELY interest us, making this a more real and human attemp at promotion. All are welcome, and I believe in your honesty! I too will be monitoring this thread and the new products/shops for interesting stuff.
Let's all do our best! I'll start;

Good luck to y'all, and please let me know if you have any new ideas about this!
