  • Reddit dominates. The most cited domain across AI engines.
  • YouTube is a strong second.
  • LinkedIn is rising fast.
  • Instagram, Facebook and Quora show up in smaller but real numbers.
  • X barely registers.
So the takeaway is simple. These are the rooms your customers are asking questions in, and they are the rooms AI is listening to when it answers them. Go be in those rooms too.
Answer the questions people are actually asking on Reddit. Make a video that solves one problem properly. Write on LinkedIn about what you are building.
And before any of it works, your own site has to be findable. AI search pulls heavily from search results, so a page that ranks has higher chances of getting cited.
That's the part Outrank handles for you: answer-first content, real backlinks, topical authority in your category.
