Should every B2B team follow the LinkedIn-first AI citation playbook?
The short version
- Across five of our client Brand Radar reports pulled in May 2026, LinkedIn appears in the top 20 AI-cited domains for only one of five. Reddit appears for two of five, ranked anywhere from #1 to #12.
- Two HVAC clients in the same country show completely different cited-source mixes once you split by audience type. B2B procurement queries pull citations from vertical trade sites. Consumer queries pull citations with Reddit at #1.
- The global "LinkedIn is the #2 AI-cited domain" finding is true at aggregate scale and one-of-five true at per-vertical scale in our sample.
- The actionable rule: do not read global citation rankings as a playbook. Run your own analysis first, then invest where your audience's queries actually pull citations from.

The research on where AI systems pull their citations from is good, well-measured and easy to read as a set of instructions. That last part is the problem.
Why the LinkedIn-first playbook breaks in four of our five client datasets
Semrush analysed 325,000 prompts submitted to ChatGPT Search, Google AI Mode and Perplexity between January and February 2026, and found LinkedIn ranked second across all three platforms, behind only Reddit. Profound’s parallel analysis of 1.4 million citations found the same trajectory: LinkedIn now ranks first across every major AI platform for professional queries.
That is the macro picture. It is real, well-measured, and easy to read as a B2B playbook.
In May 2026 we pulled the top 20 cited domains for all five of our live Brand Radar reports to test whether the macro pattern held at per-client scale.
It did not.
LinkedIn appeared in the top 20 for exactly one of the five. Reddit appeared in two. In one case Reddit ranked #1; in another it ranked #12; in three it did not appear at all.
The set of sources AI cites is far more vertical and audience specific than the global aggregate suggests.
What the cross-client cited-source mix actually looks like
| Niche | Country | Prompts | LinkedIn top 20 | Reddit top 20 | Top cited domain |
|---|---|---|---|---|---|
| Enterprise BI | US | <10 | Yes, #5 | No | Competitor's brand site |
| Real estate | IN | 100-250 | No | Yes, #12 | National property aggregator |
| HVAC (B2B) | IN | 50-100 | No | No | Vertical trade site |
| HVAC (consumer) | IN | 50-100 | No | Yes, #1 | reddit.com |
| Medical, metrology | IN | <10 | No | No | Niche specialty distributor |
LinkedIn appears for 1 of 5. Reddit for 2 of 5, ranked anywhere from #1 to #12.
Read it as one structural observation: no single global average holds for any given client. LinkedIn appears for the US enterprise BI client and is absent for the other four. Reddit appears for the consumer HVAC client at #1 and for the real-estate client at #12, and is absent for the rest.
Why audience type matters more than industry
Look at the two HVAC rows. Same country, same industry, same product category at the top of the funnel.
Same industry, different audience
Different audience, different cited-source mix
HVAC, B2B procurement
- Vertical trade sites
- Industry portals
- Specialty product directories
Reddit: not in the top 20.
HVAC, consumer
- National retail aggregators
- Price-comparison sites
- Reddit threads
Reddit: #1.
Same industry, same country, completely different cited-source mix, because the buyer journey is different.
The implication is uncomfortable for anyone selling a single B2B AI-search playbook: industry is the wrong unit of analysis when you decide where to invest for AI search visibility.
Audience type is. A consumer query pulls citations from where consumers ask. A procurement query pulls citations from where procurement researches.
Is the variance specific to LinkedIn, or does it apply to Reddit too?
Reddit varies more than LinkedIn, not less.
The same test, applied to Reddit
Reddit varies more than LinkedIn, not less
- Reddit, global rank
- #1
- Reddit in our five
- 2 of 5
If you read the global study as a playbook, you would invest in Reddit-relevant content for every B2B client. The data says that move only pays off for the consumer-leaning ones.
How to find your own cited-source mix before investing
Run it inside a week
Audit your own cited-source mix in five steps
- 01
Pick 20 to 200 bottom-of-funnel prompts
The queries where a buyer is choosing a vendor, not researching the category. These are the ones worth money.
- 02
Run them through an AI-citation tracker
Brand Radar, Profound, or a self-built scraper that hits ChatGPT, Gemini and Perplexity in turn. Pull the cited URLs.
- 03
Aggregate to the top 20 cited domains
Note where LinkedIn ranks, where Reddit ranks, and what dominates above them.
- 04
Translate the list into a distribution play
A national portal at #1 means partner with that portal. A vertical trade site at #1 means guest-post on that publication. Reddit at #1 means invest in a real, transparent community presence. LinkedIn high in the list means follow the LinkedIn approach: individual voices, weekly cadence, and the brand named in the first two sentences.
- 05
Repeat monthly
The cited-source mix is not static. AI platforms shift which domains they over-index on, and your prompt set evolves alongside them.
On step four, one detail is worth knowing before you commit to LinkedIn: naming your brand early in the post matters, because of what Seer Interactive calls the ghost-citation problem, where your content gets cited and your brand does not get mentioned.
What changes when you treat AI citation as a per-vertical question
The mental model shifts from following the playbook the research firms publish to using the research firms’ methods to discover your own. It moves you from buying a strategy to running a measurement layer.
The corpus is still the asset. The work is figuring out which corpus.
- Pull the top 20 cited domains for your top 20 to 200 bottom-of-funnel prompts before committing budget.
- Map each of the top 20 to a distribution play: publish, partner, guest-post, sponsor, or do nothing.
- Check whether LinkedIn is actually in your data, and skip the LinkedIn-first approach if it is not.
- Check whether Reddit is in your data, and if it is, audit how authentic your presence there looks.
- Repeat the audit monthly. The cited-source mix moves.
The GEO and AI SEO checklist covers the rest of the work that makes a brand citable in the first place, and running this measurement layer for clients is what our GEO service is.
