There is no reliable published figure showing how often ChatGPT recommends ADP, PayPal, or HubSpot in comparable answers. A defensible answer requires a defined set of prompts, repeated observations, and a clear distinction between a brand mention, an explicit recommendation, and a citation. Without that measurement, a percentage or ranking would be misleading.
Why there is no trustworthy frequency figure
A claim such as “ChatGPT recommends HubSpot X% of the time” is meaningful only if the underlying questions and conditions are known. The figure could change with the prompts, observation dates, ChatGPT product or model, whether Search is enabled, and account or regional conditions. A casual handful of responses cannot establish how often the system recommends a company generally.
No comparable recommendation-frequency report or company-by-company live prompt test establishes a rate for ADP, PayPal, and HubSpot. In particular, a vendor dashboard or broad AI-search benchmark should not be treated as a direct test of all three companies on the same questions.

What counts as a recommendation?
These observations answer different questions and should be counted separately:
#1 Best Overall
- Brand mention: The answer names ADP, PayPal, or HubSpot, whether positively, neutrally, or negatively.
- Explicit positive recommendation: The answer directly advises the user to consider or choose the company for the stated need. A passing mention is not a recommendation.
- Citation or link: The answer links to a company page or another source. A citation does not necessarily mean the company itself is named or endorsed; a brand can also be mentioned without a citation.
- Prompt coverage: The share of tracked prompts in which a brand appears at least once. This measures presence across questions, not the share of answers that recommend it.
- Relative position: Whether one of the three appears before or is favored over the others. This should be recorded separately from whether any company is recommended.
HubSpot’s AEO documentation makes similar distinctions among prompt coverage, visibility, competitor mentions, and citations. It notes that a source may be cited without the brand being named. Because HubSpot is both one of the companies in this comparison and the provider of this measurement product, its definitions and product claims should be understood as vendor documentation, not an independent finding that HubSpot is recommended more often.
How to measure recommendation frequency fairly
A useful comparison starts with a fixed, disclosed measurement plan rather than a broad claim about what ChatGPT “usually” recommends.
- Define the prompts in advance. Use the same questions for each company and include realistic needs, such as choosing payroll software, payment processing, or marketing software. Keep prompts neutral and do not name a favored brand unless the question requires it.
- Specify the answer condition. Record whether each result came from ChatGPT Search or a non-browsing ChatGPT answer, along with the product or model and any relevant account or regional conditions. Do not combine these conditions into one rate.
- Repeat observations over time. Record dates and repeat the same prompts on a consistent schedule. HubSpot says its tracked AEO prompts run daily and advises reviewing multiple days or weeks because responses change over time.
- Code answers consistently. For every response, record whether each company was mentioned, explicitly recommended, cited or linked, and how it ranked relative to the others. Keep neutral or negative mentions out of the positive-recommendation count.
- Report counts and denominators. State the number of prompts, repeats, and qualifying recommendations, as well as the dates and answer condition. For example, report “explicit recommendations in N of M recorded answers,” rather than an unqualified percentage.
This produces a result about that specific prompt set and observation period. It does not establish a universal ChatGPT recommendation rate, and the result can change as prompts or answer conditions change.
What HubSpot’s AI-search tools can—and can’t—show
HubSpot’s AEO product documentation describes tracking prompts, comparing competitors, and analyzing citations across ChatGPT, Gemini, and Perplexity. It lists limits of 2,500 monthly answers and 25 daily prompts for HubSpot AEO and Marketing Hub Professional, and 5,000 monthly answers and 50 daily prompts for Marketing Hub Enterprise. Those figures are plan limits in documentation last updated August 27, 2026; they are not a measure of how frequently ChatGPT recommends any company.
Rank #3
HubSpot’s public AI Search Sensor serves a different purpose: it presents a landscape view based on estimates using public information, top products, competitors, and assumed customer profiles. HubSpot says its traffic and citation trends draw on anonymized customer data and that the sensor refreshes daily. Its own documentation cautions that changes in answer-engine models can alter results. A landscape estimate is not a controlled, identical-prompt comparison of ADP, PayPal, and HubSpot.
OpenAI says public websites can appear in ChatGPT Search and advises publishers not to block OAI-SearchBot if they want content to be discoverable and cited. That is an access guideline, not a promise of visibility, a citation, or a recommendation. Likewise, OpenAI’s documentation about connecting ChatGPT Ads with HubSpot describes a paid advertising workflow—such as viewing campaign impressions, clicks, contacts, customers, and cost in HubSpot—not evidence of organic recommendations.

The evidence does not support a numerical ranking of how often ChatGPT recommends these three companies. A brand appearing in an answer, receiving a citation, or being represented in a landscape dashboard is not enough to establish an explicit recommendation rate. To make that comparison, someone would need to run and publish the same pre-defined prompts under disclosed ChatGPT conditions, repeat them over a stated period, and report the counts for each measure.
