Comparison
Bikma and Ahrefs Brand Radar both measure how often a brand is mentioned in AI answers, but on different scales: Brand Radar is the AI visibility module inside the Ahrefs suite, built on its SEO data infrastructure; Bikma is a dedicated, European platform, with five analysis dimensions, EU data and a university-validated method.
Choose Ahrefs Brand Radar if you already work with Ahrefs and want to read AI visibility alongside your SEO and backlink data. Choose Bikma if you want a dedicated, European tool, with source analysis, sentiment and Fact Checking and Fortop's consulting support.
Brand Radar is Ahrefs' product for tracking brand visibility in AI answers. The overview shows the number of mentions, AI Share of Voice against competitors and the topics associated with the brand. It offers analysis of AI answers, custom prompts, cited domains and pages, as well as views on YouTube, Reddit and web pages. The metrics are read across "6+ AI platforms", with AI Overviews, ChatGPT and Perplexity named as examples, and it relies on Ahrefs' search data infrastructure. It is part of the suite together with Site Explorer, Keywords Explorer and the other tools.
Bikma is not a module of an SEO suite, but a platform designed around AI visibility. It covers Question Analysis, Share of Voice, External Sources, Sentiment and Fact Checking, so beyond mentions and Share of Voice it analyses the external sources cited, positive, neutral or negative sentiment and the accuracy of facts. It keeps data in the EU and asks prompts in the native language, with a method validated by the University of Pisa and the University of Insubria. With Fortop behind it, the data becomes consulting and an action plan.
