Related questions
Dr Karan Rajan is based in United Kingdom and posts in English. For brands that usually means the core audience follows the same market and language, with a long tail from everywhere else — big accounts rarely stay local.
The content sits in education and lifestyle, so the people watching are self-selected for those interests. That is the useful part of a niche profile: a mid-size account inside the right category often beats a much larger general account, because the audience already cares about the subject.
If you need the same audience profile in another market, the country and language lists on CreatorFanBase let you line up comparable creators side by side instead of guessing.
If you are shortlisting Dr Karan Rajan for a campaign, these are the facts worth carrying into the brief. Everything here is stored data, refreshed on a schedule rather than typed in once.
A practical sequence: check the lead platform matches where your buyers are, check market and language, open the official account to see recent posting frequency, then ask for a media kit and rate card directly.

Dr Karan Rajan's counts come from the platforms themselves via Apify TikTok public profile and are refreshed on a schedule; the most recent check was Oct 14, 2026. When a platform blocks a read, we keep the last verified number and show where it came from instead of filling the gap with an estimate.
Large jumps are treated as suspect: a sudden drop past our safety threshold is held back for review rather than published, which is why the numbers here tend to be lower-drama than screenshots circulating elsewhere.
