Datalenk is a web analytics service built around revenue attribution: deciding which traffic source, such as search, an AI assistant or a newsletter, gets the credit for a sale. It is published by GTA Go To Agency SAS, a French company in Dijon, and was started by its founder, Florian.
A site adds one script to its pages and connects its payment provider, such as Stripe, Paddle or Lemon Squeezy. Reports then show the revenue of each channel, with ChatGPT, Perplexity, Claude and Gemini as separate channels, and funnels that show at which step paying customers drop out. Tracked links carry their source, so a visit from a newsletter or a direct message is not counted as Direct. The default script sets no cookies, so no consent banner is needed, and the data is stored on servers in Germany.
Datalenk is a subscription service priced by the number of events a month (page views, custom events and tracked payments). Every plan has every feature; there is a 14-day free trial and no free plan.
