Testimonials

I’ve been doing the SEO for my business but nothing seemed to be working, so I brought in DatGrowth to help. He changed my strategy completely, implemented a content strategy, and since then my website has seen the highest number of organic traffic in years.

DatGrowth’s key responsibilities were to work on an online strategy to develop and improve digital marketing efficiency and results and his tasks and duties included Search Engine Optimization; Link Building; SEO analytics and reporting; SEO strategy and on-site optimization.

DatGrowth helped us with our international expansion in the US and Australian markets and was responsible for SEO and project management.

As a SaaS company, our market is very specific – but thanks to DatGrowth we were able to quickly take care of the technicalities so we could focus on link building and contacting local influencers.

We especially liked Jarek’s out-of-the-box ideas in regards to email outreach and contacting media to get international references and high-quality backlinks. He didn’t just help us with SEO but also led us to acquire our first clients from abroad, which is always the hardest part for SaaS when targeting foreign countries.

We highly recommend working with DatGrowth, he is an experienced SEO expert, full of unique and personalised strategies. He also always maintains deadlines and delivers on his promise.
