Growl

Based in Sint-Niklaas, Growl has built more than 165 websites and runs SEO, Google Ads, and conversion tracking for clients who want to see which traffic actually turns into revenue rather than clicks or leads. Sites are built with structured data and a custom block system instead of a page builder, aimed at search visibility and conversion.

Services span technical and content SEO, SEO audits, Google Ads management, landing page design, and analytics and event tracking through server-side tagging. Growl's own tracking tool, paired with a feature called Pathmetrics, maps the exact path a visitor takes before converting, tying marketing activity to revenue rather than surface-level metrics. The agency holds a 4.9/5 Google review score from more than 50 reviews.
