Can you guarantee me first place on Google?

No, and you should be skeptical if anyone promises that. Search engines decide the order of results based on many factors that change constantly and that no one fully controls. Anyone who promises fixed top spots is advertising something they cannot deliver.

What we do: we set up your website technically clean, relevant in content and locally findable, so it has realistic chances of good placements for the search terms that matter to you. We make the progress visible through comprehensible metrics. How our search engine optimization proceeds in concrete terms, you can read on the SEO page.
