●Reply to most and upvote all comments people put on your memes (unless it's trolling or something.) This way people will be rewarded for clicking and commenting. This gets your memes more clicks which keeps them on the "hot" list longer.
●Don't waste your good memes on the fun stream. Memes fall off the bottom of the board too quickly on there , unless linked to Facebook or another external website. Post in MemesOverload, Sports, Gaming, Memelandia etc instead. Medium sized streams give your memes more time to catch on before disappearing off the bottom of the board.
●Post 2 to 6 memes everyday vs dozens at one shot. Your name and style stays out there, but you don't flood streams to an extent that people get sick of seeing similar memes
●Follow all your friends and upvote all their memes. They will see what you're doing and likely do the same for you.
Hope this helps. Keep up the good work!
