Using a fixed catalogue of weighted criteria. The basis is publicly documented features, pricing models, data protection information and support. Details are in our methodology.
Does TechTafel test the tools itself?
Our reviews are editorial assessments based on public vendor information. We only publish our own measurements when we have actually carried them out, and we label them explicitly.
Does TechTafel earn money from recommendations?
TechTafel uses no affiliate links. TechTafel belongs to TRYSEO UG, an SEO and GEO agency. We disclose this in every comparison.
How up to date is the information?
