Things to consider while running tg ads. I have ran ads for several big clients of mine and have approved 100s of channels in various niches. So the things i consider for any client to get them of the ground.
1. If your ads consist of several words like "Bonus", "Free", "brand names", "bad words", then it will surely go into review no matter what.
2. If you have a lot of target channels there are chances you will "ad destination quality + Irrelevant destinations" once the ads are out of review. So what i have realized is try to add only 1 channel per ad for first few ads and then clone the ads, gradually add more channels.
3. I would say recommend creating atleast 20-50 ads with different ad text as i have seen it several times they approves some of the ads.
Here are few errors which might be there once ads are out of review:-
"Destination Quality: Ad destinations must have quality, original content and provide a proper user experience."
"Prohibited content: These Ad Policies prohibit some types of content to ensure a safe and pleasant experience for Telegram users."
"Irrelevant destinations: The language of the ad and destination must match the language of the targeted channel."
"Gambling: Ads must not promote online or offline gambling, gaming, or casino-based activities involving real money, prizes, or goods of any value"
