I defo think it'll be about tattle. I completely agree with you! She's only uploading anytime she has an ad video. Surely other people will have clocked onto this as well?
I understand it might be difficult coming up with new content especially due to covid/places shut so can't get usual primark/b&m type haul videos and vlogs on holiday but instead of asking pretty much every week on insta what videos people want to see, why wouldn't she just go through her previous content to see what did well? I loved Gemmas cleaning style videos as it helped motivate me - some of them reached over 550/580k views which is more than her subs count so obviously a hit.
She's got 370k subscribers - her past 3 videos seem to have done quite poorly in terms of views because people aren't interested in bloody gift guides for your partners valentines, everything £5 haul which was again an AD then an assumptions video where it seems the majority of stuff she said was just taking stuff from here and making it into questions for herself
