International SEO, link building and digital PR agency with a Danish office in Ikast
About Seeders
Seeders is an international authority-marketing agency founded in 2012 in Zwolle, Netherlands, where its head office remains at Dokter van Deenweg 162. Its Danish office is at Strøget 38-40 in Ikast, staffed by project lead Laura Marcinkevicus, SEO specialist Frederik Olsen and account manager Nicolai Duelund. Dennis Akkerman is CEO, and Karolina Curova is managing director of Seeders Nordics. In May 2025 the group bought the Danish agency Partnertekst, whose managing partner Helge Sørensen joined the Scandinavian business. Other offices are in Den Bosch, Antwerp, Düsseldorf, Barcelona, Lyon, Warsaw, Shanghai, Hong Kong and Kigali. The team has 50 to 249 staff.
Seeders built its name on link building and digital PR. It now also sells SEO and GEO audits, multilingual and enterprise SEO, LLM optimisation, reputation management, PPC and social ads, plus white-label versions of these services for other agencies. It runs its own tools, Seeders Studio and Seeders Keystone, and its sites come in seven languages including Danish. In Denmark it offers technical SEO and local visibility on Google.dk, links from Danish domains and PR through Danish media.
Seeders has no dental service line, but it does publish healthcare-related work. In 2024 its Spanish team released an SEO study of 51 Spanish fertility clinics. Using Ahrefs, Moz and Majestic data, it compared domain authority, referring domains and traffic across markets, and found that no Spanish clinic ranked for top UK or US keywords. Its local SEO guide covers Google Business Profile verification, category choice, review requests with QR codes, consistent citations and local links, and uses a dental clinic page title as an example. Seeders is best suited to multi-location dental groups, dental tourism providers and clinics entering several countries that need authority links and PR more than day-to-day practice SEO.
The agency has more than 750 clients and has helped launch businesses in over 50 markets. It has appeared at number 87 on the Financial Times FT1000 list of fast-growing European companies, in the Deloitte Technology Fast50 in two consecutive years and in the Emerce 100. It holds Google Premier Partner status and is a Channable partner.
On Clutch, Seeders has a 4.6 rating from 17 reviews. Named reviewers include Gio Coffee, Citytrip Barcelona, Passion Digital and Grootinvloeren.nl. Reviewers mention on-time delivery of articles and links, steady communication, creative ideas, good value and gains in traffic, authority and bookings. The minimum project is 1,000 US dollars, and hourly rates run 100 to 149 US dollars.
