First, you need to understand that you're not just making Reels or TikTok for the sake of it—you're doing it to attract an audience that will eventually buy from you. This content should be directly about what you do and how well you do it. Second, you're making Reels about your work or how awesome you are at what you do. You need to understand that you can't control organic reach—when a Reel takes off and goes viral—and that's normal.
What does "control" mean in this context? You can't choose your audience, especially if you're making videos in English. How can you narrow it down, and how can you localize your content? If you're working in a specific country, use geotags. Second, use tags. And third, focus on consistency and volume. You need to systematize your content creation; your Reels should be on-trend and posted consistently.

You need to understand what budget you plan to use for this marketing campaign and targeting.
If you're in a fairly large city, a daily advertising budget of $5 or $10 will most likely not be enough to promote yourself effectively. You need to be prepared to spend between $20 and $30 every day.
How do you set up targeting? You can simply use Instagram for promotion. But the most important thing is optimization. You need to optimize for Direct Messages.
Not for clicks, not for engagement, not for brand awareness, and not for video views. You can use Facebook Ads Manager, but that will be more complicated. You also need to select your target audience.

What if we said that you don't need to collect any interests at all, and it would still work? If you create the right ad, craft the right message, and choose the right optimization, it will work.
So, you need to hook people with your creative, not with a list of their interests. Again, the "Luxury Life" interest doesn't equate to people who actually live a "Luxury Life."
That's why you can run campaigns targeting a single interest. The key is to run them frequently and test them extensively.

Just go for it. You'll never get it perfect right from the start. You have to try everything and test it out. And most importantly, understand that this is an ongoing process you'll have to deal with.
Set up your account. Potential clients need to understand where they've landed.
You need to maintain your profile. And it's very important to update it regularly and keep it filled with plenty of content.
Don't hide your older work, even if you don't like it. The more work you have, the more clients you'll attract as a result.

From our perspective, a personal blog is fine if you want one, but you shouldn't do it just for the sake of it.
If you drive a lot of organic traffic through a personal blog, you won't be able to control it. And you, for example, need customers from specific cities. So if you want to do this, by all means go ahead, but control your organic traffic using regional language, tags, and other methods.

The most important thing is your distinctive feature, your "thing," your uniqueness. Call it what you will. Over time, you'll develop your own unique style that will set you apart from everyone else. High-quality work alone won't bring you hundreds of thousands of followers. You also need to understand that buying ads will make you famous.
Advertising is a tool that will help you when you have a unique selling point that sets you apart.
