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!)

She quickly grasped the nuances of my genre and helped me devise new ways of being "found" on Amazon, as well as suggesting more appropriate avenues for reaching my audience. Her suggestions often included tutorials as well as quick responses to...

Sara was wonderful to work with. Not only was she knowledgeable and effective in optimizing my Amazon ads, but she went above and beyond to help me understand how both Amazon and other ads work so I could work on them myself at home. I highly recommend working with her!
