Testimonials
A selection of praise from current and former clients:
At MeetEdgar we had spent years building an amazing library of content but I knew it wasn't giving us as much SEO traffic as it could have been. That's why we brought in Sofie's team to optimize the content. They handled the whole process from top to bottom from determining which posts to work on, to making every necessary change and update to each post.
They made a process that had felt completely overwhelming look easy, and most importantly the results have blown way past our expectations.
After a few months of working together, we've seen an 8x improvement in the number of top 10 keyword rankings! We also saw a 185.5% increase in pageviews on JUST the posts Sofie's team worked on, and as you can imagine we've seen a huge uplift in blog traffic overall, which has then lead to list growth.
Sofie truly treats our blog as her own, and has transformed it into a revenue-generating asset.

Sofie has been instrumental in enhancing our content marketing strategy at HeySummit over the past few months. Her creativity, dedication, and strategic insights have significantly contributed to our success. I have thoroughly enjoyed working with her and highly recommend her expertise.
Benjamin Dell
Founder HeySummit
We worked with Sofie for almost 2 years on content optimization.
Her expertise in SEO is not just theoretical – it's practical and results-driven. She is well-organised, professional and responsive. She tracks what she does, measures the results and communicates it clearly to you.
As a result of our work with Sofie, we saw a notable increase in traffic to content she worked on, including articles which had never really generated significant traffic before.
If you're looking for someone to help you improve your SEO and generate more traffic from your existing content, then reach out to Sofie! You won't regret it.

I love the following testimonial because Barbara wrote this one a few years ago when she was working for Gmelius, and in 2025, she hired me again to help Caplena:
Sofie helped us increase our content pipeline by writing a set number of blog articles every month, on topics around the future of work, collaboration, project management and productivity. Sofie was super efficient. Clear in her communication, always delivering on time, making sure to anticipate / ask great questions / invest time in researching the topic in complement of our brief.
She delivered articles that were insightful, well structured, easy to snack on, and valuable for our target audience. Over the course of our collaboration, she was reliable, transparent, efficient and also super nice to work with. It would be a pleasure to work again with Sofie some day!

Sofie's audit of my website gave me so many new insights. She focused on the total picture and delivered an incredible amount of added value. I rarely meet people who can analyze at this level and turn their analysis into practical tips.

Sofie is one of the best SEO strategists I worked with. She is super organized and makes sure that we are focusing on the right things to bring results. She also tracks everything and suggests changes in our strategy and even small things like changing our fonts and overall design (of the) blog.
