I have been running telegram ads long enough to understand paid customer acquisition on channels. I have ran all kind of ads blackhat, grey hat etc. I have various channels running which I have built from scratch. Here is my take on the questions you asked:-
As you are considering broad niches its possible to grow quickly in these niches but you need to have acquisition source outside of telegram, relying completely on telegram growth itself will stall your growth.
Here is an example how I would do if i had to make a new channel in
"Tech and AI" niche:-
- I would first target mass market, what is people searching about more in these niches, what are their pain points, on which topics there is no credible info available in these niches.
- I would research competitor channels, will focus my acquisition exactly on their parameters means if they are active somewhere else then you should be making content there too.
- Look for public groups in the same niche where you can post + general niches groups also works. Lets say if public groups have 100K+ subs and people all discussing all kind of different topics there you can post your niche specific posts with discussing pain points. The interested people will directly move to your channel, its your job to keep them hooked to your channel, that you can do only by posting good quality content.
Here is answer to your questions:-
- Is choosing a broad niche still the right approach in 2026, or is it better to start with a more focused niche and expand later?
Answer: Yes, as telegram have started monetizing channels with 1000+ subs it's a good way to go, gathering as much subs from public groups becomes easy.
- How realistic is it to grow a US-focused Telegram channel from scratch on a limited budget?
Answer: You can do it free if you are smart enough about your strategies and you are consistent.
- What traffic sources have given you the best ROI?
Free traffic sources on telegram gives you best ROI, no matter how much you spend on telegram ads you won't be able to acquire that much people to make it profitable in a broad niche, but if you go micro niching and your per customer revenue is good then it makes sense spending on ads.
- How effective are the following acquisition methods today:
- Paid advertising -> Bad in a broad niche.
- TikTok / Reels / Shorts -> Good if you can go viral, but make sure you keep username something similar to your channel + provide them value/reward for joining your channel
- X (Twitter) -> Good one but you will struggle in start.
- Reddit -> Bad, will remove everything you post. But if you can ace it, it will be a goldmine.
- Cross-promotion with other Telegram channels -> Best, specifically public groups + other channel collab.
- Telegram Ads -> Moderate, but if you are in micro niche it becomes best.
- Push / pop / other vertical traffic sources -> almost all are bad for broad niche.
- Which traffic source brought the highest-quality subscribers and best retention? -> Cross posting + Tg ads + Twitter
- What subscriber acquisition costs are you seeing for Tier-1 audiences? -> For telegram ads its upto 5TON as CPM in broad niche
- Are broad content channels easier or harder to monetize than niche-specific channels? -> Easy to monetize.
I would be happy to answer more questions regarding telegram.
