Adecco AI Market Strategy Report - Staffing Agencies

Answer Capsule

Adecco ranks third in the September 2026 LLM Authority Index for Staffing Agencies, with valid recommendation coverage of 36.6% across 587 qualified observations. The brand appears in 58.1% of AI-generated responses, yet converts that presence into a valid recommendation less than two-thirds of the time, and its rank-one recommendation rate of 3.2% sits well below its overall coverage level. Adecco recorded the largest decline of any tracked brand against the July 2026 baseline, falling 7.0 points, even as it recovered sharply from an August low. The clearest opportunity is closing the gap between presence and first-position recommendation, where competitors Robert Half and Randstad are converting visibility into top placement far more effectively.

Who This Report Is For

This report is for Adecco's marketing, brand, and growth leadership, and for staffing category decision-makers evaluating how AI systems recommend agencies at the discovery and consideration stage.

Report Card

Executive Summary

Adecco enters September 2026 as the third-ranked staffing brand in the LLM Authority Index, with valid recommendation coverage of 36.6%. The brand was present in 341 of 587 qualified observations, a raw mention presence rate of 58.1%, but received a valid recommendation in only 215 of those observations. That gap between presence and recommendation is the central story of this report: Adecco is seen, but it is not consistently chosen.

The benchmark shows Adecco recorded the largest decline of any tracked brand against the July 2026 baseline, falling 7.0 points from 43.6% to 36.6% coverage. That decline is significant. At the same time, the brand recovered 20.2 points from its August 2026 low of 16.4%, which means the September figure reflects a partial recovery rather than continued erosion. The category as a whole rebounded in September after a broad August contraction, and Adecco's recovery tracked that pattern.

Adecco's strongest signal is its raw presence. At 58.1%, the brand appears in more AI-generated responses than every competitor except Robert Half and Randstad. Its positive visibility rate of 45.8% and net sentiment score of 0.79 indicate that when Adecco is mentioned, the framing is overwhelmingly favorable. There is almost no negative framing in the dataset: one negative mention across 341 present observations.

The weakness is placement. Adecco's top-three recommendation rate of 17.2% is 4.7 points below its July baseline of 21.9%, and its rank-one rate of 3.2% is less than a quarter of Robert Half's 13.5%. The brand is appearing in recommendation lists, but it is appearing lower in those lists than it did in July. Adecco recorded 19 rank-one placements in September 2026, down from 29 in July 2026.

The clearest platform signal is Gemini, where Adecco holds a 48.3% valid recommendation coverage rate and a 25.3% top-three rate, both above its overall averages. The clearest platform gap is Copilot, where Adecco's rank-one rate falls to 1.9% and its valid recommendation coverage drops to 32.7%, below its category-wide figure.

The category's recommendation-shaped answer share fell 1.2 points to 38.0%, while the valid recommendation shortlist share rose 4.3 points to 64.7%. This means AI systems are producing slightly fewer recommendation-style answers overall, but when they do recommend, they are building longer shortlists. For Adecco, that is both an opportunity and a risk: longer shortlists mean more chances to appear, but also more competition for the top positions that drive buyer attention.

What Adecco Is Winning

Questions This Section Answers

• Where does Adecco's recommendation visibility actually hold up against competitors?
• Which platform is converting Adecco's presence into recommendations most effectively?

Adecco's clearest win is its raw presence rate. At 58.1%, the brand appears in more qualified observations than all but two competitors, and its presence is broad enough to register across every tracked platform. This is not a brand with a visibility problem.

The second win is framing quality. Adecco's net sentiment score of 0.79 reflects 269 positive mentions against a single negative mention. The brand's public evidence layer is not generating cautionary or critical framing at any meaningful scale. When AI systems describe Adecco, they describe it favorably.

The third win is platform-specific strength on Gemini. Adecco's Gemini valid recommendation coverage of 48.3% exceeds its overall coverage by nearly 12 points, and its Gemini top-three rate of 25.3% is the highest of any platform for the brand. Gemini is where Adecco's recommendation conversion is working most effectively.

Adecco also holds a meaningful presence advantage over mid-tier competitors. Its 36.6% coverage leads Insight Global by 1.8 points and Express Employment Professionals by 6.6 points, though both gaps have narrowed since July 2026.

Where Adecco Has the Clearest AI Visibility Gaps

Questions This Section Answers

• Why is Adecco rarely recommended first despite appearing in most AI answers?
• Which competitors have improved their top-three placement while Adecco's position softened?
• What do the empty Pricing and Value and Multi-Brand Comparison clusters mean for how AI frames Adecco?

The primary gap is recommendation conversion at the top of the list. Adecco's rank-one rate of 3.2% places it well behind Robert Half at 13.5% and Randstad at 9.9%. Even Aerotek, which holds lower overall coverage at 31.9%, records a higher rank-one rate at 4.1%. Adecco is being recommended, but it is rarely being recommended first.

The second gap is the erosion of top-three placement. Adecco's top-three rate fell from 21.9% in July 2026 to 17.2% in September 2026, a decline of 4.7 points. During the same period, Express Employment Professionals raised its top-three rate from 4.8% to 11.8%, and Insight Global raised its top-three rate from 10.4% to 15.3%. Competitors are improving their positioning within recommendation lists while Adecco's positioning softens.

The third gap is Copilot. Adecco's Copilot valid recommendation coverage of 32.7% is below its overall figure, and its rank-one rate on that platform falls to 1.9%. Copilot represents a platform where Adecco's recommendation conversion is weaker than its category average.

The fourth gap is the absence of pricing and comparison coverage. All 587 qualified observations in September 2026 fell into the Brand Recommendation cluster. The Pricing and Value and Multi-Brand Comparison clusters recorded zero observations across July, August, and September 2026. This means the benchmark cannot yet show how AI systems frame Adecco against competitors head-to-head, or how they position Adecco on cost and value. That is a measurement gap for the category, but it is also a strategic gap: brands that build comparison and pricing content into their public evidence layer may be better positioned when those prompt types enter the benchmark.

Biggest Opportunity

Questions This Section Answers

• How many additional first-position recommendations would Adecco need to close the gap with Randstad?
• Which high-intent prompts are producing Adecco mentions without a leading recommendation?

Adecco's biggest opportunity is converting its presence advantage into first-position recommendations. The brand already appears in 58.1% of qualified observations and holds a 45.8% positive visibility rate. The gap is not awareness; it is placement. Moving from a 3.2% rank-one rate toward the 9.9% held by Randstad would require Adecco to be chosen first in roughly 39 additional observations per month, based on the current qualified denominator.

The path to that shift runs through the prompts where Adecco is present but not recommended first. The benchmark's prompt examples show that high-intent discovery queries such as "What is the best staffing agency?" and "What is the best staffing agency to work for?" are producing recommendation-shaped answers where Adecco appears but does not lead. These are the prompts where the brand's public evidence layer needs to support a stronger first-position case.

Competitive Landscape

Questions This Section Answers

• Where does Adecco rank against Randstad and Robert Half on top-three and rank-one recommendation rates?
• Why is Adecco's gap between top-three presence and first-position conversion the widest among the leading staffing brands?

Robert Half and Randstad hold the strongest recommendation-stage positions in the staffing category, with Robert Half leading on rank-one rate and Randstad leading on top-three rate. Adecco sits third, ahead of Insight Global and Aerotek on coverage but behind both on rank-one conversion relative to its presence level.

Average recommended rank covers rank-eligible recommendations only.

Adecco's position in the table shows a brand with strong top-three presence but weak first-position conversion. Its 17.21% top-three rate is third in the category, but its 3.24% rank-one rate is sixth, behind Aerotek and Express Employment Professionals, both of which hold lower overall coverage. The gap between Adecco's top-three rate and its rank-one rate is the widest among the top three brands.

Why This Matters

AI-generated recommendations are becoming a primary discovery layer for buyers searching for staffing agencies. When a hiring manager asks an AI system which staffing agency to work with, the answer shapes the shortlist before any human contact occurs. Adecco's presence in those answers is strong, but its position within them is not. The brand is being seen without being chosen first.

The next move is not more visibility. It is targeted correction of the prompt, page, and citation layers that determine where Adecco appears within a recommendation list. The benchmark shows where the brand stands. The work ahead is about moving from presence to preference.

Core Metrics

Sentiment Score

Sentiment Score = (positive mentions × 1 + neutral mentions × 0 + negative mentions × -1) / total mentions

For Adecco in September 2026: (269 × 1 + 71 × 0 + 1 × -1) / 341 = 0.7859.

This score matters because unclassified mention counts are misleading. A brand that appears frequently but is described neutrally or critically is not in the same position as a brand that appears frequently and is described positively. Adecco's score of 0.79 reflects a public evidence layer that is overwhelmingly favorable, with almost no negative framing.

Share of voice is a diagnostic metric, not a business KPI. Knowing that Adecco appears in 58.1% of qualified observations does not tell you whether those appearances are helping or hurting. A positive recommendation, a neutral reference, a cautionary mention, and a competitor-displaced mention are not equal. Counting all mentions as wins is bad measurement. Classified sentiment is required before interpreting AI visibility, because it separates presence from persuasion.

Sentiment by Platform

Methodology

1. This report is a benchmark-based analysis of Adecco's position in the LLM Authority Index AI Market Discovery Index for Staffing Agencies, not a client implementation case study.
2. The reporting window is September 2026, with comparisons to July 2026 as the baseline and August 2026 as the intermediate month.
3. Six AI/search surface families were tracked: ChatGPT, Copilot, Gemini, Perplexity, AI Overviews, and AI Mode.
4. The benchmark began with 800 prompt-surface observations and produced 587 qualified observations after qualification. Brand-level percentages use the qualified observations as the public denominator.
5. The competitor universe includes 16 tracked brands: Adecco, Aerotek, AppleOne Employment Services, Employbridge, Express Employment Professionals, Insight Global, Kelly Services, Kforce, ManpowerGroup, Openjobmetis SpA, PeopleReady, PrideStaff, Randstad, Robert Half, Spherion, and Staffmark Group.
6. One public high-intent cluster was measured: Best Recruiting and Staffing Agencies, classified under the Brand Recommendation buyer-intent class. The Pricing and Value and Multi-Brand Comparison clusters recorded zero qualified observations in the current series.
7. Stage 0 extraction retained the query, AI surface, answer, brand outcome, recommendation placement, sentiment, and, where exposed, citations or attributable evidence sources. Source presence is evidence about the information environment and is not automatically proof that the source caused the recommendation.
8. A mention is counted when Adecco appears in a qualified observation, regardless of recommendation status.
9. A valid recommendation is counted when Adecco receives a positive recommendation with a rank between 1 and 10, as marked by the dataset.
10. The unique question count for September 2026 was 536. The public version does not expose the full unique prompt list.
11. Average recommended rank covers rank-eligible recommendations only. Openjobmetis SpA has no rank-eligible recommendations and is shown as N/A.
12. Limitations: the benchmark does not measure market share, attributable sales, every possible AI response, organic-search ranking positions, social media mention volume, private or sponsored channels, or causality from a metric movement alone. Small-count brands such as AppleOne Employment Services, Employbridge, and Staffmark Group should be interpreted with caution.
