Why it exists

Web Traffic trend data, without the plumbing

Similarweb-class tools sell dashboards with enterprise contracts. Trends API gives you the traffic signal as JSON at usage-based pricing: the live ranking of the most-visited websites globally, plus attention trends for any domain through the same endpoint.

Because traffic attention is normalized to the same 0-100 scale as search and social sources, you can ask compound questions: is this company's web attention growing while its search interest flatlines? That divergence is often the story.
