Why Reddit & LinkedIn get cited most

In one line

Semrush data (January 2026) found Reddit and LinkedIn are the two most-cited domains across ChatGPT, Perplexity and Google AI Mode, because AI models lean on authentic community discussion and professional expertise.

Why these two

AI engines value real human opinion and demonstrable expertise. Reddit supplies candid, high-signal discussion; LinkedIn supplies professional authority and firsthand experience. Both are heavily crawled and trusted, so brands and people active there get pulled into AI answers far more than their own sites alone would earn.

How to show up

Participate authentically, answer questions and share genuine expertise in relevant subreddits and on LinkedIn, mentioning your product only where it truly helps. Don't spam; both platforms punish it and it backfires. Presence in these communities is a rare lever that lifts AI citation and SEO at once.

Frequently asked

Should I post on Reddit and LinkedIn for SEO?

For AI visibility especially, they're the most-cited domains in AI answers (Semrush, Jan 2026). Contribute real value; overt promotion gets removed and hurts you.

Do these mentions need to link to me?

Even unlinked, positive mentions build the brand recognition AI engines reward. Links help too, but the mention itself has value.
