Its local SEO service is the most relevant to dentists. It names dental practices and physiotherapists under health and wellness, and uses a Cologne dentist search as an example. The local work covers setting up and verifying the Google Business Profile, with hours, photos, service descriptions, Q&A and regular posts. It also covers local keyword targeting, consistent name, address and phone details across directories, a process for gathering Google reviews and answering negative ones, local service pages and blog posts, and links from local associations and events. The general SEO process runs from a technical audit, including Core Web Vitals and crawling, through on-page and off-page work to reporting on rankings, traffic, visibility and enquiries.
They have no named dental clients. Clients include Essers and Comfort Offices. Feedbax reviewers include Green2B and the Cologne cultural association Kölner KulturPaten.
