Sara Usera – Marketer

Digital marketer with a tech and analytics background to help you get those sales going! Mentored by Reedsy's CMO. Expert on Amazon Ads.


UPDATE: Thank you so much for your requests! I'm very happy that I got the chance to work in different projects for multiple authors, but as of now I am mainly looking for Amazon ads projects: Setting up campaigns/Optimising accounts. If you need help with your Amazon ads, let me know!

I come from the full hardcore digital marketing world, having worked almost 4 years for one of the biggest, fastest growing digital agencies/consultancies at a global level. Eventually, I grew tired of working for a big firm with big clients for 24/7 and decided to take all that knowledge and go freelance, allowing me to actually work and invest time in projects I love.

How did I come around book marketing? I always loved books, likely buy more than I ever will read (super-fan of Amazon's "Buy now with 1-Click" button for Kindle!), and was lucky enough to know Ricardo Fayet, Reedsy's CMO, who needed support helping authors do their marketing. I have been working hand in hand with him in multiple projects for more than half a year now, and feel absolutely ready to take projects of my own! The type of projects I have worked on include the following:

- Ad campaigns on Facebook ads and Amazon advertising
- Marketing plan development
- Amazon audits (Blurb, cover, categories & keywords used)

Some additional tasks I could help you on given my background in digital marketing:
- Implement Google Analytics (understand the traffic you are getting to your site)
- Implement Facebook Pixel, or any other ad tool pixel on your site (Generate remarketing audiences of people really interested in what you write)
- Website audits in case you want to lead traffic to your site (do not let them get away without taking a good look, or even converting!)

Working as a digital marketer for digital agencies as well as authors — this last part mentored by Ricardo Fayet, Reedsy's CMO.

Bertelsmann is a huge European conglomerate owner of, amongst other companies, Penguin Random House.
