This is twitter advice, but I assume it works.

I had about 10k followers and about 100 likes per tweet in my heyday - but had pretty much left about a year before elon took over, and fully left when he did.

It was a lot of work with little reward, but it was fun.

• Post actually engaging content for your niche on a regular schedule, preferably more often than twice a day
• you can maybe stretch to two niches on an account but likely you just want one
• engage primarily with people in that niche
• get to know them, build an online friendship
• get into group dms or chats with multiple people in the same niche
• nepotistically retweet each others stuff, publically respond favorably to it
• unless you have a really interesting life, keep your real life out of it and focus on your niche
• expect this process to be a committed 12 month process - so that's at least 1000 posts, all should be high quality enough to warrant engagement.
