Earnings:
Be REALISTIC You will have slow days, your earnings will fluctuate, privilege also plays a massive role. Growth will come, with time and patience
NEVER EVER GIVE OUT CONTENT BEFORE YOU HAVE RECEIVED PAYMENT.
DON'T only rely on one format to make your income (subscriptions/ppvs/customs etc) by varying your income formats you're more likely to make a consistent income.
-Subscriptions mostly depend on promoting, if you take a break or lose the platform you use for promotion , your earnings are affected.
-Tips/customs/PPVs rely mostly on having "good buyers" or the right type of buyer for the content you offer, if you lose those buyers or they are unable to buy extra content at the time, your earnings are affected.
If you are recieving funds in a foreign currency (eg non US for onlyfans) you will likely be charged a currency exchange fee by your bank
Some subs do just randomly delete their profiles often right after subscribing, you keep the money from deleted accounts.
While I understand the importance of bills etc you need to remember that a customer isnt subscribing to see you beg post after post, by all means mention things you may want contributions towards but posting about it more often won't increase your chances. Less is more.
Instead of phrasing it as
"Tip me I need money"
Say
"Any contributions made go towards supporting both me and my page"
Consider having something like a weekly campaign pinned for your bills instead of asking on every post daily, try and have incentives for tipping.
If you're in findom this doesn't necessarily apply to you^^
