Cologne, Germany
If an SEO agency in Cologne is steadily building domain authority in a competitive market and pulling in links from a diverse range of sources, that tells me two things. One, they understand long term SEO, not quick hacks. Two, they can actually get other sites to care enough to link to them, which is a big credibility signal. Do they practice what they preach? From what you’ve got here, yes, at least on the authority and backlink side. I’d be comfortable shortlisting them, but I’d still ask to see how that authority translates into real traffic, rankings, and leads for their own site before signing anything. You want proof that this growing strength is not just theoretical but driving business for them, because that’s what you’re ultimately hiring them to do for you.
