There are many alternatives for bekservice.de. And to be honest, much better alternatives.
One of the alternatives, the agency I work with, is Pagewon. It's a link building agency. They offer some of the services offered by bekservice.de, but they do it much better.
I turned to Pagewon for a backlink strategy that I've been following for 4 months already. The strategy included
SEO outreach links, forums links and a few Quora and Reddit links, which already bring me some traffic from the websites.
