TikTok shares push content past the audience it already reached, which is the point, but they are also the least visible number on the page — most readers never look at the share count. Their value is distributional rather than cosmetic, so judge a seller on whether the reach actually moved, not on whether the counter went up.
TikTok distributes by content rather than by follower graph, which changes what a purchase is worth. A video reaches people who do not follow you, so followers do less work here than on any other platform — and views, which push a video through the algorithm's early test, do more. That is why views are the cheapest service on TikTok and usually the right first purchase, and why buying a large follower count on an account whose videos are not being shown solves the wrong problem.
Beyond the metric itself, the same four things separate a working order from a wasted one, and none of them are visible from a landing page. First: whether the seller asks for your password. No legitimate provider in this category needs one — a public username or a post link is all the work requires — and a request for a login is the end of the conversation, not something to weigh against a lower price.
Second: whether the price you are quoted is the price you pay. Retail sellers here quote packages and panels quote a rate per 1,000, and the gap between them once you normalise is routinely fiftyfold. Every figure on this page has been converted to the same per-1,000 unit for exactly that reason.
Third: what the refill promise actually says. "Refill guarantee" is a marketing phrase until you read the window, the trigger and the process. Thirty days, automatic, no receipt required is a real guarantee. Thirty days, on request, subject to review is a support ticket you will probably not bother to file. Fourth: whether the seller has been trading long enough to still exist when you need the fourth one. Domain age is on every provider's page here, and it is the cheapest signal in the category.
