Christine is a business coach for wellness entrepreneurs. She has a website where she regularly publishes advice related to that topic. She designed a Pinterest page with boards that attract her target customers. She regularly shares images on Pinterest with a link that leads back to the advice on her website. The images she posts on Pinterest contain compelling text that make people want to learn more, so they pay a visit to her website to read her tips and advice. This is targeted traffic from people who may decide to sign up for her mailing list. Some will go on to buy her services or products.
She also repins useful information published by others. Repinning, by the way, is the act of sharing existing pins on Pinterest. These people reciprocate by saving her images to their boards. Elsewhere, people that specifically search for information about wellness topics and activities also save Christine's images to their boards for future reference. The more her images are saved to different boards, the greater her chances of appearing towards the top of Pinterest search results.
As her content is spreading on Pinterest, more and more people engage with it (i.e. click on the image and/or click through to her website). It may even start turning up in people’s home feed. As long as her content continues to get engagement on Pinterest, her advice will turn up in search results. For weeks, months and years to come.
Oh, and thanks to Pinterest, Christine's business also appears on the first page of Google.
