Introduction: webometrics has been recognized as a science with great potential for application in various fields. However, studies in this area are still restricted to the large field of informetrics. Moreover, the debate surrounding the relation between the web and the health field has been dedicated to addressing issues of socioeconomic nature related to universal access and a new division between north and south. Objectives: with the aim of contributing to the broadening of webometrics to other areas of knowledge, this study intends to map on the web, in the light of international cooperation models, relations between major health research institutions. Results: results showed predominantly thematic groupings, the reflection of a north-south cooperation model and a low expression of relations between institutions of south countries.
