How Often Does AI Cite LinkedIn? 19 Months of Data, LLM by LLM

rocketblue tracks which sources AI engines cite when they answer real buyer questions. We looked at 47.2 million citations from April 2025 to October 2026. Then we measured how many of them pointed to LinkedIn, month by month and model by model.

The 60-second version

• LinkedIn earned 0.53% of all the AI citations we tracked. That is about 1 in every 190 links.
• LinkedIn’s share has roughly tripled in a year. The average across six LLMs went from 0.20% in October 2025 to 0.62% in October 2026.
• Google AI Overviews hit its highest LinkedIn share yet in October 2026, at 1.01%.
• Perplexity had the biggest single month of any LLM, at 1.57% in February 2026. Grok peaked at 1.44% in May 2026.
• ChatGPT cites LinkedIn much less. Its share was 0.29% across the whole period.
• Gemini almost never cites LinkedIn. Only about 1 in 21,000 Gemini citations pointed there.

The interactive chart

Click an LLM to turn it on or off. The dashed white line shows the average of the LLMs you have turned on. Hover over a month, or tap it on mobile, to see the exact numbers.

Gaps in a line mean we did not have enough data for that LLM in that month. For example, we tracked too few Grok answers in June and July 2026 to report them.

Why half a percent is a big deal

Half a percent sounds small. But AI citations are spread across a huge number of websites. In our State of AI Search report for July 2026, the top 25 most-cited domains made up only 10.6% of all citations. LinkedIn was one of the five most-cited domains in that report.

So one website earning 1 in 190 AI citations is a lot. Very few single domains do better. And LinkedIn is a site where any brand can publish for free.

LLM by LLM: who cites LinkedIn, and how much

Google AI Overviews and AI Mode: the steady climbers

Google’s two AI search features cite LinkedIn more than most models do. Since April 2026, AI Overviews has pointed to LinkedIn in 0.7% to 1.0% of its citations. In October 2026 it reached 1.01%, its highest month in our data. AI Mode peaked at 1.07% in April 2026 and was at 0.80% in October 2026.

Both Google features lean on LinkedIn articles and posts. In October 2026, articles and posts made up 76% of the LinkedIn links in AI Overviews and 78% in AI Mode.

Grok: the heaviest user, with a twist

Grok barely cited LinkedIn in late 2025. By May 2026, 1.44% of its citations pointed to LinkedIn. That is about 1 in 70 links. Since August 2026, its share has stayed between 0.7% and 0.9%.

Grok cites a different kind of LinkedIn page than the other models. In October 2026, 63% of its LinkedIn links went to company pages. Another 9% went to job listings. Grok seems to use LinkedIn to look up facts about companies, not to read their posts.

Perplexity: a big spike, then a cool-down

Perplexity did not cite LinkedIn at all until mid-2025. It then climbed fast and reached 1.57% in February 2026. That was the highest month for any LLM in our data. Since then, its share has moved between about 0.4% and 1.0%. Like Google, Perplexity mostly cites LinkedIn articles and posts, at 79% of its LinkedIn links in October 2026.

ChatGPT: a light touch

ChatGPT cites LinkedIn far less than the models above. Its monthly share has stayed between 0.11% and 0.41%. In October 2026 it was 0.30%. That is less than a third of the AI Overviews rate in the same month.

Gemini: almost never

Gemini is the clear outlier. We tracked about 3.3 million Gemini citations, and only 157 of them pointed to LinkedIn. That is roughly 1 in 21,000. This is striking because Google AI Overviews and AI Mode cite LinkedIn often. Our data does not show why the Gemini app behaves so differently from Google’s search features.

What this means for your brand

• LinkedIn matters most for Google and Perplexity. If your buyers use Google AI Overviews, AI Mode, or Perplexity, LinkedIn content is worth real effort.
• Write articles and posts that answer real questions. Google and Perplexity mostly cite LinkedIn articles and posts. A post that only links to your website gives them little to quote.
• Keep your company page complete and up to date. Grok cites LinkedIn company pages more than anything else on the site. Your page should clearly say what you do, who you serve, and where you work.
• Do not count on LinkedIn for ChatGPT or Gemini. These models rarely cite it, so other sources will matter more there.
• Watch the trend, not just one month. Shares swing a lot from month to month. Perplexity went from 1.57% to 0.44% in a single month.

Methodology: rocketblue sends a weekly set of prompts to each AI engine, using a local IP to mirror how a real user in a given country would ask. We record every source cited in each answer. LinkedIn share is the number of citations pointing to linkedin.com, its country subdomains (such as uk.linkedin.com), or lnkd.in, divided by all citations for that LLM in that month. Look-alike domains are excluded. An LLM-month is shown only when it has at least 10,000 citations, so early months for some models are left out. Claude and Copilot are excluded because we had too few citations to report them reliably. The average line is the simple mean of the selected LLMs that have data in a given month. Citation counts reflect rocketblue’s prompt mix across customer brands, not each engine’s real-world market share. All figures cover April 1, 2025 to October 31, 2026.
