About me

My name is Cristina Dias Costa. I’m Portuguese and multilingual, with extensive experience in traditional marketing. For 17 years, I worked at Belgium’s leading telecommunications company, developing expertise in strategic marketing and advertising campaigns.

Since returning to Portugal in 2021, I have expanded my knowledge into digital marketing, investing in specialised training and applying it to paid online ads, digital strategies, and website design.

Fluent in Portuguese, French, English, and Dutch, I work with international clients in digital marketing and offer translation services, language lessons, and multilingual support for businesses and individuals.

Reviews

Cristina Costa is an outstanding professional in every sense of the word. She is someone you can truly rely on, which, in my experience as a business owner, is becoming increasingly rare.

She showed total dedication to the work and offered absolutely exceptional support throughout. The results far exceeded our expectations.

Her ability to understand and connect with the needs of the Language Institute sets her apart.

In addition to her marketing work, Cristina also works as a language trainer, and in that area too, she stands out for her competence, dedication, and empathy with students. This leads me to believe that in any task she undertakes, Cristina gives her full commitment and always delivers her best. I sincerely hope to continue working with her.

Cristina is the first person who truly monitors, optimizes, and regularly discusses my Google Ads account with me. I can turn to her with all my questions, and they are resolved very quickly. Since then, my Google account has been running optimally, and I’ve been attracting many new customers. Cristina is a true professional in her field. Working online is absolutely no obstacle — everything runs smoothly, and Cristina’s Dutch is perfect.

Other agencies I worked with in the past set up the Google Ads account and claimed to provide follow-up, but that turned out not to be true.
