I would not recommend running any sort of PPC ads for OFM. There are way better strategies like mass-scale story reactions or M/S that you can utilize for OFM which will convert at a much higher rate. Let me just include an excerpt that covers OFM traffic generation via story reactions so you can get a better idea of the sort of options you have available for IG-based OFM.
"So let’s take an OnlyFans model and say we want to run 100 custom accounts for her. We’d take 100 aged, infantry accounts and rebrand each of them to look like the real, main account of the model. We want to try to make these accounts appear legitimate so we take our time adding new posts, adding captions to them, placing a high-converting bio, and obviously, an OF link (ideally a linktree for safety) right below the bio. Once we’re done with the branding process, we have 100 customized infantry accounts representing the model that are ready to start interacting with the target users.
Once we settle on the accounts whose followers we believe are the ideal audience for this model (usually accounts of other OF models with similar characteristics), we proceed to run the exact same strategy as described in Strategy #2: Story Reactions.
We run only story reactions on these accounts because, again, story functionality enables us to interact with a much greater amount of targets on a daily basis than is possible with any other action such as follows, likes or comments whilst keeping the accounts relatively safe. Watching stories doesn’t elicit as many action blocks as no explicit “action” is taking place(excluding the obvious API calls that is). Interacting with the stories themselves carries the average action limit of 2.2k per day, exceeding follows by 1,100%. An average account running this strategy will have a “soft” reach of roughly 9,000 - 10,000 users per day via views and a “hard” reach of 1000 - 2000 users per day via story reactions (likes, quizzes, sliders, polls, etc.) The latter action results in notifications and having our account appear at the top of the story view list and thus, has a higher likelihood of resulting in a conversion.
In the context of an OF model, this method can be very OP because to most target users, it’ll appear as if some random, attractive girl had viewed and/or liked one of their stories. They’ll be inclined to go check out the infantry account that had interacted with them and this is where the Infantry Custom Accounts strategy starts to deviate from the King - Story Reactions strat: the funnel optimization options.
Because we’re no longer as concerned about losing our accounts, we are free to enable certain funnel optimization actions like Welcome DMs to users that followed one of our infantry accounts. In the context of an OF model, perhaps we’d say something like “Thanks for following my page, check out the link in bio to receive a free gift”. It’d obviously be a bit more persuasive than that but you get the idea. Now, if you’re having 100 of these accounts, each sending out 30 Welcome DMs per day, that becomes very powerful in terms of redirecting traffic. Welcome DMs often exhibit a far higher open and conversion rate than Mass DMs (another strategy I’ll be covering later in this chapter) because they go directly to the target’s general inbox instead of the requests folder.
Some of my OF agency clients have taken it a step further and use virtual assistants to conduct custom chatting operations with the leads and have on-going discussions with them via the Direct Manager module. All Welcome DMs or regular DMs sent from your infantry accounts will appear in that module and you can use it to have a full-on conversation with your converted targets if the need arises. This is especially useful if you’re in a small market niche that generally has a longer sales cycle like certain course-sellers, real estate agents or high-ticket BDRs. You’re able to send more customized messages and engage in a more organic conversation with your leads, minimizing the losses that come with sending generic, “click link in bio” message templates."
Hella long excerpt, I know, but just giving you some ideas for what's possible on IG. OFM is a very versatile niche so you can get very creative with how you generate your traffic instead of relying purely on IG Ads.
