Movement

This is the first edition on this tier, so no move can be computed for Mercer yet. From the next edition this section shows, per buyer segment, whether its share moved by more than the measured noise floor.

By model

How each model treated Mercer across every prompt where it was named for a mid-market B2B company. Twelve models, six prompts per category.

By framing

Which of the six questions produced the naming. By model says how often; this says asked what. The first-choice count on the right carries the marks of the models that produced it.

What the models said for it

Verbatim evidence the judge attached to positive labels.

“Buy one major survey (like Robert Half or Mercer) to ensure you are paying within the 25th–75th percentiles” Qwen 3.7 Flash · Compensation benchmarkin · paraphrase prompt · first choice

“The strongest fit from the results is Mercer or Salary.com/Compdata for broad benchmarking” Perplexity Sonar · Compensation benchmarkin · paraphrase prompt · first choice

“Especially strong in pay and total rewards benchmarking, plus HR strategy.” GPT-5.4 mini · Compensation benchmarkin · comparative prompt · first choice

“For HR: Choose Mercer/Radford for legally defensible board reviews” Gemini 3.5 Flash · Compensation benchmarkin · comparative prompt · first choice

And against it

Verbatim evidence attached to negative labels. A warning on a product with few labels is a warning; on a product with many, it is one voice among them.

“Avoid over-investing in Mercer/WTW unless you have global complexity” Kimi K2 · Compensation benchmarkin · paraphrase prompt · hard negative

“Avoid traditional surveys (Mercer/Radford: $10k+/year) unless scaling.” Grok 4.1 Fast · Compensation benchmarkin · budget prompt · hard negative

“high-end, legacy enterprise surveys like Mercer, Radford (Aon), or Willis Towers Watson (WTW)—which can easily cost $20,000 to $40,000+ annually—are generally out of reach” Gemini 3.5 Flash · Compensation benchmarkin · budget prompt · soft negative

“legacy giants like Mercer, Radford (Korn Ferry), and WTW dominate the Fortune 500, they are often cost-prohibitive for mid-market firms” Qwen 3.7 Flash · Compensation benchmarkin · direct prompt · soft negative

A head-to-head page exists where both products are in a category's top three. The other rows are the same fact without a page behind them, so they link to the product instead.

What carried it into the answer

The sites and pages cited by the answers that named Mercer. A fact about retrieval, not a lever on the model.

Citations exist only for the models that return a source list, four of the twelve in this edition, so these counts come from 82 of the 109 answers that named Mercer and are not a share of its labels.

Is this your product?

Claim this page

Claiming is free and changes nothing in the data. A claimed page shows a verified contact who is told when each edition publishes and when Mercer's standing changes by more than the noise floor; the right to propose corrections to the vendor table, meaning names the judge wrote that should or should not read as Mercer, applied by version and listed in the change log; and a one-line description supplied by the vendor and marked as such.

It does not get any change to labels, shares or verdicts, any preview, or any say over which quotes appear. A verification link goes to your work email; an address at mercercapital.com is approved on the spot, any other address is reviewed by hand.

Your name and company appear on the claimed page, or the company alone if you ask below. A title and a LinkedIn address appear there too if you give them, and are left off if you do not. Your email address is never published.
