Lisbon SEO agency with dental and clinic SEO pages and a published Algarve case
About The Key SEO
The Key SEO is a search-focused agency with its main base on Avenida da República in Lisbon. It began in Brazil. It was founded in 2019 and has a team of 2 to 9 people (some listings say about ten collaborators), with branches in Portugal, Spain and Brazil. It has Portuguese addresses in Lisbon, Évora, Coimbra and Viseu, Spanish ones in Murcia, Torrevieja and Carrizo de la Ribera, and one in the Tijuca district of Rio de Janeiro. Rodrigo Filardi is an SEO consultant in Lisbon. The team works in English, Portuguese, Spanish, Italian and French. That helps clinics that market to visitors and expatriates.
The agency has dental SEO pages in English and Portuguese and a separate page for health, aesthetic and wellness clinics. Its dental process has six stages. It starts with a competitor review and keyword research into what patients type into Google and AI tools. It then moves to on-page work on copy, code, images and video, and link building through mentions on dental and health sites. After that come technical and mobile fixes, and finally ongoing tracking with a monthly online report. Local SEO is handled through Google Business Profile. The agency also offers GEO, which aims for visibility in AI-generated answers. Its Portuguese marketing service for dentists adds Google Ads, social media content and email campaigns for keeping patients.
The main proof is a one-year case for an unnamed dental clinic in the Algarve, from May 2023 to April 2024. Keywords in Google's top three rose from 4 to 50. First-page keywords grew from 22 to 148. Average monthly organic traffic went from 242 to 1,801 users. Clinic testimonials come from SP Clinic in Lisbon, Milênio Clinic and Amado Clinic. These clinics got better visibility, more qualified enquiries and close follow-up. A dentist, G. Rothier, saw the practice pass its largest Portuguese competitor within three months.
On review platforms, Zaask shows a 4.7 rating, and the agency carries Zaask's Marca Recomendada badge. TechBehemoths shows 5.0 from five reviews from 2019 and 2020 and named the agency a 2022 winner and a finalist from 2023 to 2025. Reviewers there praise its ranking results and strategy. It is also a Google Partner.
The agency works on a monthly retainer, but no fee levels are published. A free SEO analysis and a tailored proposal come first. The agency fits independent clinics in Portugal that want SEO-led growth with monthly reporting, especially those seeking international or dental tourism patients.
