I’m Marta Sierra, the creator of Digibites Marketing and a freelance consultant focussed on socially meaningful projects. 

I like to immerse myself into every new project and I take pride in always making sure I offer the best strategy for every brand. 

Thanks to my wide experience working on Digital Marketing in different sectors and agencies, I have been lucky to meet other professionals, some of them are still my colleagues today.

What they say about me

«Marta is a digital marvel. She is the safest pair of hands you could wish to have looking after your digital media – and absolutely always meets or exceeds (even the most ambitious of) targets! As well as being incredibly insightful and clearly expert in the space, Marta is a joy to work with. Her light approach, and ability to remain calm and solutions-focused in all circumstances is really something. In short, we couldn’t recommend her more highly.»

“Marta is wonderful and I would highly recommend her! I was slightly cautious at the beginning as I knew nothing about digital marketing, and I certainly didn’t understand SEO…. However, Marta very quickly out me at ease and my confidence grew immediately. We were able to build a strategy that worked for us and then Marta ‘held my hand’ while we implemented it, teaching me every step of the way. It was a great success, and we were all thrilled with the outcomes. Marta has a fountain of knowledge and the most wonderful approach helping us to grow in so many ways.
