Seeing this ranking is step one. AI Rankia is the autonomous AI-visibility platform that acts on it— where read-only tools (Profound, Otterly, Semrush) just hand you a report, AI Rankia's agents publish the content AI cites, deploy the schema, llms.txt and internal links straight to your live site, buy the links AI already trusts for your competitors, and prove the citation lift against a control. Its Get Cited PR toolkit finds the journalists and creators who cover marketplaces de segunda mano and automates the whole outreach — discover contacts, AI-write each pitch, send from your Gmail and track replies. Switch on autopilot and the agents run the entire loop end to end, every day — Monitor → Get Cited → Content Hub → AI Links — or take full manual control of every article, prompt, schema tag and link. Built for the teams that own marketplaces de segunda mano visibility: agencies reporting to clients, and brands who want to move up this ranking instead of just watching it.
