Google Ads dashboards tell Recruitment and HR Tech advertisers exactly what they paid per click and per lead; they rarely show what share of that spend ever reached a real HR buyer. Lunio's invalid traffic data layer sits underneath the standard benchmark numbers to close that gap between reported performance and real buyer reach. Find out how much of your Google Ads budget is being wasted →
Google Ads auctions for Recruitment and HR Tech keywords are unusually crowded with searchers who will never buy software. Per GrowthSpree's Q1 2026 data across 30+ HR Tech SaaS accounts, between 60% and 80% of unfiltered HR Tech ad traffic goes to non-buyers, job seekers typing "[company] careers," employees looking for their employer's HRIS login, leaving only 5–15% of traffic from the VP HR, CHRO, or Director of People Operations the ads are meant to reach. This audience overlap compresses CTR and inflates effective cost per real buyer before invalid traffic even enters the picture.
| Campaign Type | IVT Rate | CPC |
|---|---|---|
| Search | 6.88% (estimated) | $8–$25 category terms, up to $60 competitor terms |
| Performance Max | 10.41% (estimated) | Not yet benchmarked for this vertical |
| Display (GDN) | 15.88% (estimated) | $0.78 (Employment Services proxy) |
| Demand Gen | 10.00% (platform-level proxy) | Not yet benchmarked for this vertical |
IVT rates above are calculated by applying Google Ads' verified platform-level IVT baselines to the 32.07% lead-gen uplift confirmed in Lunio's dataset, flagged here as estimates pending vertical-specific coverage. On device split, mobile versus desktop CPC and CPM data doesn't exist for this vertical specifically; the buying committee behind most HR Tech purchases, HR, IT/Security, Finance, and Legal, per SHRM, tends to research software on desktop during work hours, making desktop the more defensible device to bid up on category terms until account-level data says otherwise.
GrowthSpree's HR Tech dataset doesn't break out CPC by device, and no vertical-specific mobile/desktop split exists in available external research for this combination. Directionally, Terra's 2026 cross-industry benchmarks show mobile conversion rates typically lagging desktop by one to two percentage points across most industries, consistent with a buying committee that evaluates HR software during the workday rather than on mobile. Treat desktop as the primary bid-up device for HRIS and ATS category terms until your own account confirms otherwise.
| Metric | Average | Notes |
|---|---|---|
| CTR | 1.30% (Search, B2B benchmark) | Low CTR reflects search pollution rather than weak creative. In HR Tech, a Search CTR climbing above 2–3% is more often a sign of bot-inflated clicks or job-seeker query matching than genuine buyer engagement. |
| ROAS | 553% (Search) / 436% (Performance Max) | B2B cross-vertical benchmark, per 42 Agency, 2026. Reported ROAS in HR Tech is structurally understated because the GCLID used for offline conversion tracking expires at 90 days, before many HRIS and Benefits Admin deals with 90–180 day sales cycles close. |
CPC and CTR figures above draw from GrowthSpree's Q1 2026 HR Tech SaaS account data and 42 Agency's 2026 B2B benchmark set. For this combination, every IVT figure in this article is a cross-vertical proxy built from Google Ads' verified platform-level baselines combined with the 32.07% lead-gen uplift documented in the Lunio 2026 Global Invalid Traffic Report. These estimates will be replaced with vertical-specific figures as Lunio's HR Tech dataset expands. Calculate how much you're losing →
Campaign type determines far more than CPC in this vertical; it determines which of the three overlapping HR Tech audiences your budget actually reaches. The breakdown below treats each campaign type's IVT exposure as distinct from, and additive to, the human non-buyer pollution problem.
Search is the primary active-intent channel for HR Tech SaaS, carrying an estimated 6.88% IVT rate (Search baseline of 5.21% adjusted for the 32.07% lead-gen multiplier). Category terms run $8–$25 and competitor terms $30–$60 per GrowthSpree's 2026 data. Google's AI Max for Search autonomously expands audiences and creative, and per Lunio's analysis of AI Max risk for Search campaigns, AI Max increases IVT exposure by roughly 35% above the Search baseline, a meaningful compounding risk for a vertical already fighting three overlapping search audiences.
Performance Max carries an estimated 10.41% IVT rate (PMax baseline 7.88% adjusted for lead-gen). 42 Agency's 2026 B2B data shows PMax delivering 436% ROAS versus 553% for Search, Search outperforms for lead gen. Without account-level brand exclusions, PMax will serve on branded and competitor login queries, claiming conversions from employee self-service clicks that then enter the same Smart Bidding signal pool as any bot-generated form fills. GrowthSpree recommends capping PMax at 20–30% of total HR Tech budget with strict brand exclusions and page feed restrictions.
Display (GDN) carries the highest estimated exposure among standard placements at 15.88% (Display baseline 12.02% adjusted for lead gen), with a $0.78 CPC per the WordStream Employment Services proxy. Display CTR above 1% for B2B SaaS is a practical diagnostic red flag, legitimate B2B Display CTR should sit in the 0.3–0.6% range, and anything higher is more likely bot-inflated clicks than genuine awareness lift.
Demand Gen campaigns, Google's replacement for Discovery, grew 192% year-over-year in spend per BrightBid's 2026 benchmarks. No HR Tech-specific IVT figure exists for this format; applying the overall Google Ads platform baseline (7.57%) and the lead-gen multiplier produces a working proxy of roughly 10.00%.
Search Partners carry no published IVT figure, but multiple practitioners flag the network as a disproportionate source of junk conversions in lead-gen verticals. HR Tech demo request forms, typically just name, email, and company, are trivially easy to fabricate, making Search Partner traffic a candidate for exclusion or close monitoring rather than default inclusion.
| Country | IVT Rate |
|---|---|
| United States | 8.44% |
| United Kingdom | 7.97% |
| Germany | 6.34% |
| France | 6.63% |
| Australia | 7.87% |
| Canada | 6.29% |
The US combines the highest country-level IVT rate (8.44%) with the deepest competitor-term bidding war, most of the $30–$60 competitor CPC range reflects Workday, ADP, Rippling, and BambooHR competing for the same enterprise buyer, all headquartered in and primarily targeting the US market. That makes the US the clearest double-risk market for HR Tech advertisers: highest cost per click layered with the highest invalid traffic exposure. The UK follows at 7.97%, still above the global cross-industry reference point. Germany (6.34%) and Canada (6.29%) offer relative efficiency, with lower IVT rates and typically less saturated HR Tech competitor sets. See Lunio's ad fraud data by country for the full regional breakdown.
Take a mid-market HR Tech SaaS advertiser spending $240,000 a year on Google Ads, at a blended CPC of $12 across category, competitor, and long-tail terms. That's roughly 20,000 clicks a year. At a 2.5% form-fill conversion rate, that's 500 demo requests annually, at a reported cost per lead of $480. Apply the estimated 10% blended IVT rate built from Google Ads' 7.57% platform baseline and the 32.07% lead-gen uplift confirmed in the Lunio 2026 Global Invalid Traffic Report, and 2,000 of those 20,000 clicks are invalid, $24,000 a year spent on clicks that never had a chance of reaching a real HR buyer. The true cost per lead, once invalid form fills are stripped out, rises to an estimated $533–$565, 11–18% above what the dashboard reports. At enterprise scale, with $1 million or more in annual Google Ads spend, that waste climbs to an estimated $100,000–$150,000 a year, alongside 200–450 fake leads polluting the CRM and distorting Smart Bidding's conversion signal.
This pattern isn't unique to HR Tech. Funding Circle, a UK B2B lending platform running a comparable MQL-gated, high-CPC lead-gen model on Google and Microsoft Ads, reduced its average IVT rate by 81.41% (from 16.84% to 3.13%) and saw a 10% increase in MQL conversion rate after working with Lunio, see the Funding Circle case study for the full breakdown. The structural parallel is direct: a business with a lead-gen funnel, high-value competitor keywords, and an offline conversion tracking model finding that a meaningful share of its reported conversions weren't real.

Benchmarks tell you whether your CPC or CPL sits near the HR Tech average; they don't tell you whether that number represents real buyers or a blend of job seekers, employee self-service clicks, and invalid traffic. For a vertical already losing 60–80% of unfiltered traffic to non-buyers, adding an estimated 7–16% IVT rate on top makes the gap between reported and real performance too large to plan a budget around. Lunio's traffic audit replaces the cross-vertical proxies in this article with your account's actual numbers.

Category terms like "HRIS" or "ATS" run $8–$25, while competitor-name terms against vendors like Workday or BambooHR reach $30–$60, per GrowthSpree's Q1 2026 data across 30+ HR Tech SaaS accounts. Cross-industry "Employment Services" averages of around $2 are not applicable, since that category blends in job-board advertisers bidding on entirely different, lower-cost keywords.
A Search CTR around 1.30%, consistent with 42 Agency's 2026 B2B benchmark, is normal for HR Tech SaaS given the vertical's search pollution problem. A CTR climbing above 2–3%, particularly on Display at above 1%, is more often a sign of bot-inflated clicks or non-buyer query matching than a genuinely well-performing ad.
Invalid traffic sits on top of, not instead of, the human non-buyer pollution already common in HR Tech. Bot-generated clicks and form fills are often tracked as legitimate conversions, feeding Smart Bidding a signal that looks identical to a real demo request, which pushes the algorithm to keep serving ads to the audiences and placements generating that traffic.
The US carries the highest verified country IVT rate at 8.44%, compared with 7.97% in the UK, 6.63% in France, 6.34% in Germany, and 6.29% in Canada. For HR Tech advertisers, the US combines this higher IVT rate with the most expensive competitor-term bidding, making it the clearest double-risk market in the data.
