Key takeaways
- Across 20 test prompts, both ChatGPT and Perplexity named staffing agencies far more often when the query included a niche or a city, not when it was generic ("best staffing agency").
- ChatGPT builds its recommendation by fanning a single prompt out into multiple background searches, then blending review-site data (ClearlyRated, Glassdoor, Indeed) with editorial rankings (Forbes, Staffing Industry Analysts) and Reddit threads.
- ChatGPT cites roughly 5 sources per response versus Perplexity's roughly 10, so a staffing agency has about half the citation slots to fight for on ChatGPT compared to Perplexity or Google AI Overviews.
- Reddit's citation share on ChatGPT Search collapsed from about 3.8% to 0.5% in mid-August 2026, meaning r/recruiting threads that used to feed these answers are becoming a weaker channel, fast.
- Boutique agencies with a specific niche and third-party award data (ClearlyRated Best of Staffing, Clutch) outperformed generalist brand names in our tests, the same pattern Autotrader beats Chevrolet in ChatGPT's automotive citations.
Why this question matters right now
Staffing is a weird industry to search for. There's no Yelp-style consensus, no single "best" answer, and the buyer (a hiring manager) usually has one shot at getting it right. So when someone types "recommend a recruiter for hiring software engineers" into ChatGPT instead of Googling "best tech staffing agency," the agency that gets named in that answer has a real shot at a client conversation that never touches a search results page.
I wanted to know: does this actually happen? And if it does, which agencies get picked, and why?
To find out, I ran 20 prompts spanning employer-side queries ("who should I use to hire a CFO"), candidate-side queries ("which recruiters specialize in healthcare IT"), and comparison queries ("staffing agency vs in-house recruiter cost") through both ChatGPT and Perplexity, then cross-referenced the pattern against a July 2026 test run by Loudmink and Promptwatch's citation data for context on how these engines source their answers generally.
What we actually tested
The 20 prompts fell into four buckets, mirroring how a real buyer or candidate would phrase a question:
- Employer shortlist queries: "best staffing agency for hiring software engineers nationally," "top executive search firms for a healthcare CFO," "contract-to-hire IT staffing agency in Austin"
- Candidate discovery queries: "which recruiters specialize in cybersecurity," "best recruiting agencies in Chicago reviews"
- Trust and legitimacy checks: "is [agency name] legit," "[agency name] Glassdoor reviews"
- Pricing and model comparisons: "how much do staffing agencies charge," "staffing agency vs in-house recruiter cost"
Generic prompts (bucket 1 without a niche or location) rarely produced a named agency. Add a niche, a city, or a role level, and both engines got specific fast.
What ChatGPT actually does behind the scenes
This is the part most people get wrong. Older guidance on staffing SEO assumed ChatGPT was just pattern-matching against training data, recognizing brand names it had seen before. That's outdated. When citations are enabled, ChatGPT Search runs live web searches and decomposes a single prompt into a chain of sub-queries.
For a prompt like "recommend a recruiter for hiring software engineers," a July 2026 test by Loudmink found ChatGPT running searches like:
- "best software engineering staffing agency"
- "top executive search firms for [industry]"
- "contract-to-hire IT staffing agency in [city]"
- "Forbes America's Best Professional Recruiting Firms 2026"
- "ClearlyRated Best of Staffing IT [state]"
- "is [agency] legit / [agency] Glassdoor reviews"
- "reddit recommend a staffing agency"
That last cluster matters: the answer isn't just "who can do the job," it's "who can do the job AND is safe to work with." ChatGPT is explicitly checking reputation signals before it names a name.
This matches what Promptwatch's research on ChatGPT's use of the site operator found more broadly: on August 8, 2026, ChatGPT Search started using the site: operator at scale, jumping from roughly 0.4% to 17% of all fan-out queries almost overnight, and running nearly twice as many searches per response. Staffing queries, with their heavy fan-out pattern, are exactly the kind of question this change was built for.
The agency that kept showing up
Across repeated runs of the software-engineering hiring prompt, one name surfaced consistently: INSPYR Solutions, an independent tech-staffing firm, not one of the giant generalist brands you'd expect. It holds ClearlyRated's Best of Staffing awards at the Client 5-Year Gold and Talent 15-Year Diamond tiers, meaning 76.6% of its clients and 71.8% of placed candidates rated it 9 or 10 out of 10, well above the industry average of around 55% and 50% respectively.
Two other patterns repeated in our tests:
- Motion Recruitment kept surfacing for narrow tech-contract queries because it owns one lane (IT contract and direct-hire staffing) instead of claiming to do everything.
- Kforce showed up on broader, reputation-driven prompts, likely because it has a 3.8 average across more than 2,600 Glassdoor reviews plus thousands more on Indeed. Sheer review volume seems to act as a trust floor even when the agency isn't a specialist match.
Meanwhile the big editorial-style credibility source is Forbes America's Best Recruiting and Temp Staffing Firms, built from a Statista survey of 13,800 recruiters, HR managers, and job candidates between November 2025 and January 2026. Robert Half topped professional recruiting again, Korn Ferry led executive search for roughly the ninth year running, and Manpower took the No. 1 spot in temp staffing for 2026. None of the three, notably, showed up as the top pick in our niche prompts, which suggests these rankings function more as a legitimacy check than a direct recommendation engine.
Why specificity wins
Generic "we staff everything" agency pages give ChatGPT nothing to match against a specific query. The agencies that surfaced consistently had dense specialty signals (a named niche, a named region, a named role level) plus third-party validation (award badges, review scores) plus, in some cases, structured data on their own site.
This mirrors a pattern Promptwatch found in a completely different vertical. In its August 2026 automotive citation data, ChatGPT cited marketplaces like Autotrader (5%) and Cars.com (4.6%) ahead of every individual car manufacturer's own site, with Chevrolet the only manufacturer to crack the top eight at 2.62%. Marketplaces and listing sites accounted for nearly 15% of citations combined, versus under 8% for manufacturer sites directly. Staffing looks headed the same direction: expect marketplaces and review aggregators like Indeed, Glassdoor, Clutch, and ClearlyRated to keep outranking individual agency homepages in citation share, the same way Autotrader beats Chevrolet.
How ChatGPT and Perplexity differ as research engines here
The two engines don't behave the same way, and the difference matters for where a staffing agency should focus its content effort.
| Factor | ChatGPT | Perplexity |
|---|---|---|
| Avg. sources cited per response | ~5 | ~10 |
| Citation consistency | Fluctuates with model updates | Highly stable day to day |
| Reddit reliance | Was a Reddit specialist, share fell from ~3.8% to 0.5% in Aug 2026 | Leans YouTube over Reddit for social sources |
| LinkedIn usage | Treats it like a company directory: LinkedIn homepage and company pages, plus job listings at 8% | Prefers ordinary feed posts over Pulse articles |
| Best format to target | Specialty service pages and "best of" listicles | Consistent citation behavior makes it a good testbed for content changes |
Fewer citation slots on ChatGPT (about 5 per response, according to Promptwatch's data on average sources per response) means competition for each mention is tighter than on Perplexity or Google AI Overviews, which cites roughly double that, around 10 sources per answer. If you're a smaller agency trying to break into AI answers, Perplexity's larger citation pool and steadier behavior make it a more forgiving place to test whether a new page or award badge moves the needle before you chase ChatGPT.
One more wrinkle specific to staffing: LinkedIn. ChatGPT treats LinkedIn almost like a company directory. Its top-cited LinkedIn surfaces are company pages (23.84% of LinkedIn citations) and even the raw homepage (22.55%), with job listings punching above their weight at 8.02%, per Promptwatch's breakdown of LinkedIn citation page types. That's the opposite of Google AI Mode and AI Overviews, which strongly prefer LinkedIn Pulse articles (over 40% of their LinkedIn citations each). If you're a staffing firm optimizing for ChatGPT specifically, a clean, current LinkedIn company page might do more for you than another thought-leadership Pulse post.
The Reddit shift you need to know about
For most of 2025 and into mid-2026, Reddit was ChatGPT's single biggest citation source by a wide margin, and staffing-related subreddits like r/recruiting and r/jobs fed a meaningful share of those "is this agency legit" checks. That changed abruptly. Promptwatch's data on Reddit citations dropping in ChatGPT shows Reddit's share of ChatGPT Search citations falling from roughly 3.8% to 0.5% on August 14, 2026, an 86% relative collapse that has held since. Google's AI Overviews and AI Mode saw only gradual declines over the same window, nothing close to a cliff.
What this means practically: if your GEO strategy for a staffing brand was leaning on seeding Reddit threads to shape ChatGPT's "legitimacy check" step, that lever just got a lot weaker on ChatGPT specifically. It's still working on Google's surfaces. Don't abandon Reddit, but don't treat it as your primary channel for ChatGPT anymore either.
What actually moves the needle for a staffing agency's AI visibility
Based on what surfaced consistently in our test prompts and what the citation data explains about why, four things showed up again and again:
- A named niche on the homepage and service pages, not "we staff all roles." "Contract-to-hire IT staffing in Austin" beats "full-service staffing solutions."
- Third-party validation the AI can find and verify: ClearlyRated Best of Staffing badges, Clutch reviews, a healthy Glassdoor and Indeed review volume.
- A clean, current LinkedIn company page, since ChatGPT treats LinkedIn as a directory more than a content platform.
- Fee-transparency content. Direct-hire fees typically run 15-25% of first-year salary and contract markups commonly land 25-75% over pay rate; publishing real numbers gives AI engines something concrete to cite when someone asks pricing questions, which our comparison-query tests picked up on repeatedly.
Tracking whether it's working
Running these prompts by hand every month is fine for a one-off test, but if you want to know whether a given agency is actually gaining or losing ground in ChatGPT and Perplexity answers over time, you need something that checks this on a schedule and flags the shifts. Tools like Promptwatch track prompt-level citation share across ChatGPT, Perplexity, Gemini, and Google's AI surfaces, and they show which of your own pages are actually getting cited versus which competitor or review site is winning the mention instead.
For a staffing agency specifically, that kind of tracking would tell you, for example, whether your ClearlyRated badge page is the one getting cited, or whether it's still your generic "about us" page losing out to Glassdoor. Given how fast the Reddit shift happened in August 2026, checking manually once a quarter isn't going to catch changes like that before they cost you visibility. If you're weighing options in this category more broadly, the directory of GEO software at bestgeosoftware.com is a reasonable place to compare platforms side by side.
The honest limits of this test
Twenty prompts is a sample, not a census, and AI answers change week to week, sometimes faster than that. The August 2026 Reddit citation collapse is a good reminder that whatever pattern you observe today can shift in a matter of days if the underlying model changes how it fans out queries. Treat any single test, including this one, as a snapshot, not a verdict. If staffing agency visibility in AI answers matters to your business, the only real answer is to keep testing, not to read one article and assume it's settled.
One thing does seem durable, though: engines want proof, not adjectives. "Award-winning" means nothing to ChatGPT. A ClearlyRated Diamond badge with an actual NPS score behind it does.
