Reddit’s recent partnership with G2 signals a new era for B2B brands and their buyers — one where community credibility becomes just as important as traditional content and SEO. As large language models reshape how buyers find and trust vendors, community social sites are quietly becoming a critical place of influence. Reddit’s more than 115 million daily active unique users (up 19% year-over-year), 68% of which are not on LinkedIn per Reddit, places them among the top tier for a wide number of distinct communities (e.g., subreddits for /business, /marketing, and /sales). What’s more, Reddit boasts that tech decision-makers heavily use the site for peer reviews (72%) and product research (49%). The partnership with G2 means Reddit’s rich, community-driven content alongside G2’s trusted customer reviews will be more valued by LLMs and more likely to be surfaced in AI-generated responses. The burning question for B2B marketers is whether it’s now time to build a presence.

AI Changes The Discovery Game

With G2 data powering Reddit business profiles and Reddit content licensed to AI models, information about B2B brands will be increasingly surfaced through community conversations and verified reviews.

In an AI-mediated buying journey, visibility isn’t just about SEO. It’s now SEO + AI engine optimization (AEO). Businesses want AI assistants to reference them, recommend them, and cite them. Research shows that while LLMs look at branded content, they overwhelmingly prefer third-party sources when surfacing answers. A brand’s presence across review sites and community spaces is essential to an effective AEO strategy. Reddit knows this. Its lawsuit against Perplexity and its partnership with G2 are part of a strategy to defend and monetize the power of authentic conversation. B2B buyers are already searching Reddit. Now AI will too — but in a structured, attributable way.

Brand perception in independent, community-driven spaces — where the brand doesn’t control the narrative — is now a competitive advantage.

The Fear Factor: Brand Safety And Control

Real talk happens in community sites and forums — the good, the bad, and the brutally honest. For marketers used to polished campaigns and gated e-books, that can feel risky. Many B2B brands avoid Reddit because they fear losing control. Reddit isn’t a thought-leadership playground. It’s a community ecosystem where trust is earned, not self-declared. Overly promotional brands get downvoted, ignored, or called out.

The fear is reasonable, but it’s colliding with the new reality. Today’s business buyer expects transparency and candid conversations, the kind that happen in community sites and forums. Forrester research shows that they look to third parties for validation on social media and other channels. For example, social media ranks just behind AI as the most influential resource in the buyer journey according to Forrester’s Buyers’ Journey Survey, 2025. And Reddit specifically overindexes with younger buyers — Gen Z and Millennials — who are now the majority of buying group members in B2B purchasing.

How B2B Marketers Should Define Their Strategy

Assess the risk/reward level and develop a thoughtful engagement plan before jumping in. Success in community spaces isn’t about controlling the message — it’s about participating in the conversation. B2B brands should think twice before opting out of community-driven reputation building. AI is watching and buyers are talking. Winning brands will:

  • Listen before speaking. Understand communities and norms first.
  • Invest in credibility. Encourage real reviews, feedback, and advocacy from customers.
  • Show up with value. Respectfully answer questions, not push messaging.
  • Align review sites with presence in customer communities. Create a consistent trust ecosystem.

Review sites like G2 build validated customer proof. Community social sites like Reddit amplify authentic discussion. Together, they will shape brand legitimacy in the age of AI. B2B marketers should leverage the trust that is built in these spaces to influence both human and machine-driven decision-making.
