Undoubtedly she is one of the biggest Pinfluencers out there. Her boards are organized with curated content, including her blog collaborations, her sponsored posts and also her line created for Target. I follow her and have noticed her pins are constantly updated. Let's say she signed a contract with a certain brand. Here's what she could offer as an influencer: she will be able to offer different packages including Instagram posts, Pinable images for Pinterest, Blog posts, e-mail content and the list goes on... since her following is huge in all of these platforms, she can offer different services and also get paid according to each package. I don't know the services she offers, this is just an example of the kind of work a Digital Influencer can offer.
If you go back a few years, you will see Beth used to blog about lifestyle before she became a teacher to creatives. You will see pins of her Gift Guides graphics, which included brand collaborations she's done in the past. You will also see posts from her blog, food photography, etc... What she's doing is pretty simple: she's cycling her content through her different platforms and speaking to her audience from different places on the web. And since her voice is so powerful, she can share her gift guides and even include the graphic crafting into her Media Kit. Again, I'm just using her account as an example.
She is doing something I've seen other fashion bloggers do. She pins "shopable pins" from brands she works with. I've designed Media Kits for bloggers before and one of the services they offer is "pining direct shopable links", which simply means they will be signing a contract that will include them promoting a certain product with the promise to pin a link to buy that same product on their Pinterest page. If they have a big following on Pinterest, that service is actually very interesting. I'm not sure whether Jordana chose to pursue that path, but what I can see is that her content is well thought out and it's very cohesive.
