Summary
Picture a real estate broker in Tampa who reads that AI search is changing how people find businesses. Every example she sees is about newspapers losing traffic or advertisers changing budgets. She wonders if her industry is even part of the story yet.
GDELT tags each article with themes that include industries and occupations, such as advertisers, publishers, retailers, attorneys or tourism. We compared how often each industry tag appears in AI search articles with how often it appears across a 31 million article sample of all news.
Advertisers appear 27.4 times more often in AI search news than in news overall, and publishers 10.7 times more. Those are the industries the press sees as most tied to AI search. Health care, education and travel are under-represented, though health care and local trades are rising fast in 2026.
What we measured
For AI search articles (matched by URL slug for Google AI Overviews and AI Mode, ChatGPT search, Perplexity and AI search engines), we counted how many carry each of 23 industry-related GDELT theme tags. For the baseline, we counted the same tags across every article GDELT processed on the 5th and 20th of each month from January 2023 to September 2026.
Over-representation (lift) is the tag's share of AI search articles divided by its share of all news. A lift of 2 means the industry shows up twice as often in AI search coverage as in news generally. Theme tags are assigned automatically from article text, so they reflect mentions of an industry or occupation, not the article's main subject.
Advertising, software and publishing dominate the AI search story
Industries that appear more often in AI search coverage than in news overall:
Lift vs all news
| Industry | GDELT tag | AI search articles | Share of AI search articles (%) | Share of all news (%) | Lift (x) |

The top of the list follows the money. Advertisers and publishers are the two groups whose revenue depends most on search clicks. Telecom and capital markets reflect coverage of AI companies' deals and funding. Plumbers show a 7.3x lift on a small base of 36 articles, almost all from 2026.
Health, education and travel are under-represented
Industries that appear less often in AI search coverage than in news overall:
| Industry | GDELT tag | AI search articles | Share of AI search articles (%) | Share of all news (%) | Lift (x) |
|---|---|---|---|---|---|
| Housing and real estate prices | ECON_HOUSING_PRICES | 235 | 1.07 | 1.4 | 0.8 |
| Journalism (journalists) | TAX_FNCACT_JOURNALIST | 241 | 1.1 | 1.63 | 0.7 |

Health care is tagged in 16.68% of all news but only 7.10% of AI search coverage. Tourism appears in 2.88% of news and 0.54% of AI search coverage, even though travel planning is a common use of AI answers. These gaps suggest the press has not yet connected AI search to many consumer industries.
Health care and local trades rose sharply in 2026
Share of AI search articles carrying each tag, 2024 vs January to September 2026:
| Industry | Articles 2024 | Share 2024 (%) | Articles 2026 | Share 2026 (%) |
|---|---|---|---|---|
| Medical and health care | 300 | 6.23 | 715 | 12.6 |
| Legal (attorneys) | 3 | 0.06 | 139 | 2.44 |
| Software as a service | 19 | 0.39 | 141 | 2.48 |
| Contracting (contractors) | 4 | 0.08 | 109 | 1.92 |
| Housing and real estate prices | 27 | 0.56 | 116 | 2.04 |

Medical themes doubled their share. Attorneys, contractors, plumbers and dentists barely appeared in 2024 and now show up in dozens to more than a hundred AI search articles each. Advertisers and publishers fell in share as the story broadened.
Legal and publishing coverage is the most negative
Average tone of AI search articles by industry tag (tags with 150+ articles):
| Industry | Articles | Average tone | Share below -2 (%) |
|---|---|---|---|
| Capital markets (IPOs) | 378 | -0.95 | 25.7 |
| Publishing (publishers) | 1,196 | -0.88 | 31.9 |
| Legal (attorneys) | 248 | -0.87 | 42.7 |

Articles that mention attorneys, IPOs, publishers or telecom lean negative, reflecting lawsuits, regulation and traffic disputes. Articles mentioning software, contractors, real estate and transport lean positive.
What this means
If your industry is under-represented in the coverage, that does not mean AI search is passing you by. It may mean fewer of your competitors have read about it yet. Health care, home services, legal and real estate are now starting to show up in AI search news, and the businesses that act first may hold the advantage in AI answers for longer.
Find out what AI tools say when customers in your area ask for a business like yours. Our free AI visibility audit checks the questions that matter in your industry and shows where you stand; if you later want a GEO agency to act on it, you will know exactly what to ask for.
Limits
GDELT theme tags are automatic and mark mentions of an industry or occupation, not the main subject of an article.
The baseline samples two days a month, about 31 million articles, rather than every article.
Some tags are small. Plumbers (36 articles) and dentists (22) give rough estimates only.
AI search articles are matched by URL slug, so coverage that does not name AI search in the URL is excluded.
