MentionShare measures how often your brand appears in AI-generated answers. Here is why it matters more than domain authority in 2026.
For years, B2B marketers obsessed over domain authority, keyword rankings, and organic traffic. These metrics made sense in the Google era. But as buyers shift to AI assistants, we need a new metric.
Enter MentionShare.
MentionShare is the percentage of AI-generated answers that mention your brand, across a defined set of buyer-intent prompts.
For example: if you run 10 prompts across ChatGPT and Perplexity, and your brand appears in 3 of the responses, your MentionShare is 30%.
Domain authority measures how likely Google is to rank your page. But Google rankings are becoming less relevant as buyers use AI.
MentionShare measures something more important: how often AI recommends your brand to potential buyers at the moment of purchase intent.
A brand with a DA of 20 but a MentionShare of 60% will out-compete a brand with a DA of 80 and a MentionShare of 5% — because AI is becoming the primary research channel.
