Nowadays its a lot about content. Marketing it is 1 thing, if you're really good - you won't even need any form of strong FB ads. Word of mouth will get you there.

First off is what's different between you and other centres? (i'm presuming yours is a tuition centre) What's your selling point or best course? ie. your champion is teaching Mathematics and you've got like, some sort of awesome technique to help students understand the subject.

So you either:
- reveal some of these techniques (sort of like giving teaser) online to get the 'buy-in' from parents and students alike. Often times people don't know whether you're good or not, so they hesitate to sign up. AND/ OR,

- show real results of students' achievement or how you've helped them score with whatever techniques you've got to 'sell'. AND/ OR

- show how your centre is different compared to everyone else (otherwise, why would the students join you?), ie. selling point could be you've got top grade teachers who is the best in A, B and C subjects. AND/ OR

- your centre could offer something extra/ special that other centres rarely do. For example, idk, ie. shuttle van service to pick up and drop off students so parents don't have to worry, study room for group studying at leisure (with teacher's support to guide them on their homework anytime), special App for learning that only your students have access etc etc.

Basically when people wanna subscribe to your service, you'll need to give them a strong reason to do so. Why? because it validates the choice/ decision. Make your contents SO GOOD that they'll be missing out if they don't sign up (but make sure you're not just boasting, and that you're REALLY GOOD in the first place). But if you're just average, make sure to up your game.

Once you've got strong contents, push it out with some advertisement on social media or create some sort of campaign for your existing students to share out.

Lastly, also verify who should be your target audience - whether its the parents or the students and where they're potentially at. That's where you'll want to push your contents.

Doesn't mean you can't apply some of the things I've mentioned previously.
Nothing is without effort - just like how your students gotta study to make it. Same with you too, read up more, browse more, observe more and build your own competitive advantage. If you're starting from Ground 0, make a plan that's practical and do-able. Then build your portfolio and adjust it slowly from there.

IMO if you've no solid footing to start with, attach yourself somewhere (ie. prominent tuition centers) and build your portfolio first. If "you" yourself going to be the selling point, then make your profile look good and stand out.

No problem. Thank me later with a coffee when you've made your breakthrough alright jk, all the best.
