Who publishes it
The ranking is published by Ronald Renaud. He is also the author of the ranking and the guides; his page is at /authors/ronald-renaud/.
How the site is funded
The publisher describes the site as a personal project with no advertising. There are no affiliate links on the site, and no vendor listing links to a lead form.
How vendors are selected
The candidate list combines a manual list of test automation service providers with vendors whose own sites rank in search results for the primary query. Every candidate is collected with the same instruction and the same sources: the vendor's site, Clutch, G2, GoodFirms, certification registries and public case studies. Twelve vendors are ranked. The rule for the cut is completeness of public data across the eight scoring dimensions: a company with more than two dimensions that have no public evidence does not enter the ranking.
How the order is set
The eight dimensions and their weights were fixed before any vendor data was collected, and the scales are published on the methodology page. Each vendor is scored against those scales, and the total is computed from the weights at build time. The first place is whatever that calculation returns.
How it is updated
Review counts, ratings, certifications and rates are re-checked on each update. The date the data was last checked is shown at the top of every page. Corrections follow the editorial policy.
