The majority of her income revenue is earned through her blog, rather than social media. Hence she seldom has ads etc on instagram (in comparison to other influencers anyway).
Her audience is largely American based, so she does have a USP of being a rich, young mother with a successful career, wholesome, handsome rich husband.... She's like a real life British Carrie Bradshaw. Though she's not. It's all smoke and mirrors for those of us who can see through the deception and cunningness.
There are people who'll read her blog though and believe she does lunch with Liv, gets invited to number 10 and does really speak like that. Then there are those of us who know she once went for lunch at a restaurant and Liv was there at another table and no communication occurred, the 10 downing street pic was just from an organised tour and her voice doesn't really sound like Peppa Pig speaking in received pronounciaton while getting high on helium and lemonade. They'll believe her clothes and handbags are genuine and that she lives in a fancy Notting Hill townhouse instead of a split level rented studio. And for as long as they click onto her website, brands will pay money to her, to sell a slither of this Rosie (her name is Rose, ironically she detested being called Rosie in the past, but I digress) *lifestyle* to whoever purchases their products.
Good luck to her I say. It cannot be particularly great for her mental health though.
