Customer advocacy is visible in recommendations, reviews, repeat support, community participation, and creator-led influence. The available research shows that trust is the foundation, while review volume, responsive service, and credible peer voices make advocacy easier for prospective customers to see and use.

Trust, recommendations, and brand advocacy
Recommendations from people customers know remain one of the clearest forms of advocacy. In Nielsen’s 2021 Trust In Advertising Study, 88% of respondents globally said recommendations from people they knew were the advertising source they trusted most. Nielsen’s population covered people aged 15 and older across 56 countries, so this result is a broad global survey response rather than a measure of one market’s referral rate.

The 2019 Edelman Trust Barometer Special Report: In Brands We Trust? connected trust with willingness to advocate. Across its reported eight-market average, 51% of respondents said they would advocate for a brand they trusted, compared with 24% for a brand they did not trust. Trust also appeared to prompt unsolicited support: 57% said they had advocated for a trusted brand even when they were not directly asked for advice, and 76% said they always recommend a trusted brand when someone asks.
Edelman’s country cuts show that advocacy was not uniform geographically. The share saying they advocated for a trusted brand was 45% in the United States, 71% in China, 66% in India, and 43% in the United Kingdom. These are 2019 measurements and should be read as the original report’s market-specific survey responses, not as current country rankings. 2019 Edelman Trust Barometer Special Report: In Brands We Trust?
| Trust and advocacy measure | Result | Measurement period |
|---|---|---|
| Trusted recommendations as most trusted advertising source | 88% | 2021 |
| Would advocate for a trusted brand | 51% | 2019 |
| Would advocate for a brand not trusted | 24% | 2019 |
| Always recommend a trusted brand when asked | 76% | 2019 |
For marketers, these findings point to a practical distinction: advocacy is not only a campaign response. It can happen spontaneously when a customer has enough confidence to volunteer a recommendation, and it becomes more available when another person actively asks for advice.
Customer reviews as visible advocacy signals
Reviews turn private customer satisfaction into public evidence. BrightLocal’s Local Consumer Review Survey 2024 found that 75% of U.S. consumers always or regularly read online reviews when researching local businesses, while only 3% said they never did. The survey focused on U.S. consumers researching local businesses, so these figures should not be generalized to every category or country.
Google was used by 81% of U.S. consumers to read online reviews in 2024. Other platforms also played a role: 16% used Apple Maps and 10% used Trustpilot. Review research was often multi-platform: 77% used at least two platforms, and 41% used three or more. This makes a consistent customer experience important beyond a single review profile.
Consumers also used review tools to judge recency and credibility. BrightLocal reported that 96% found Google’s review-search function useful in some way, while 47% rated its sort-by-newest function highly useful. A majority, 59%, said a business should have 20–99 reviews for its average star rating to feel trustworthy. Freshness mattered too: 27% expected local-business reviews to be as recent as two weeks when making decisions.
Responses from the business itself were another advocacy signal. In the same 2024 U.S. survey, 88% said they would use a business that replied to all of its reviews. In a blind test, 58% unknowingly preferred an AI-generated review response over a human-written response. The result measures preference in that test; it does not establish that automated replies are always more effective or more authentic.

How reviews influence purchase decisions
PowerReviews’ 2023 survey shows how strongly reviews participate in purchase research. Ninety-eight percent of shoppers said reviews were an essential resource when making purchase decisions, and 99.5% said they researched purchases online at least sometimes. Regular or always-online research was reported by 87% of shoppers.
The presence of review content also affected where people chose to shop. Seventy-seven percent specifically sought websites displaying ratings and reviews. Ratings and reviews affected whether a product was purchased for 93% of shoppers. They were especially useful for unfamiliar products: 74% used them to learn about products they had never purchased before, and 98% were more likely to read reviews for a product they had not bought previously.
Review absence created friction. Forty-five percent said they would not buy a product if no ratings or reviews were available. Price and perceived risk could increase scrutiny: 78% said they read more reviews when considering an expensive product. At the brand level, existing reputation could partially compensate for missing product reviews, with 63% saying they were more likely to buy a product without reviews when other products from the same brand had a high overall rating.
| Review-related purchase behavior | Share of shoppers |
|---|---|
| Reviews are an essential purchase resource | 98% |
| Ratings and reviews affect purchase | 93% |
| Would not buy with no ratings or reviews | 45% |
| Read more reviews for an expensive product | 78% |
| Seek websites with ratings and reviews | 77% |

Customer service experiences that create advocates
Customer service can either reinforce advocacy or interrupt it. Qualtrics’ 2024 Global Consumer Study covered 23,273 consumers in 23 countries. Globally, 55% were satisfied with the amount of time they waited during their most recent contact-center experience, and 63% were satisfied with their overall contact-center experience.
The country results varied substantially. Wait-time satisfaction reached 78% in China but was 38% in South Korea. Overall contact-center satisfaction was 82% in China and 49% in Japan. These figures are satisfaction responses from the study’s named population and period, not universal service benchmarks.
Resolution on the first contact was another important measure. Sixty-two percent of global consumers said their issue was resolved the first time they contacted customer service. The country figures ranged from 83% in India to 25% in South Korea. Qualtrics reported that when an issue was resolved on the first try, consumers were 2.1 times more likely to recommend the brand to friends and family than when it was not resolved on the first try.
The relationship between service and advocacy is therefore measurable at the experience level: first-contact resolution is associated with a greater likelihood of recommendation in this study. It should not be presented as a guaranteed causal multiplier for every organization. Global Contact Center Trends, 2025
Social creators, communities, and user-generated advocacy
Advocacy now travels through social creators and communities as well as direct personal recommendations. HubSpot’s January 2024 U.S. consumer survey found that more than 20% of social-media users had bought a product based on an influencer recommendation during the previous three months. Among influencers whose recommendation inspired a purchase, 62% had fewer than 10,000 followers and 25% had fewer than 1,000. These results suggest that purchase-influencing advocacy is not limited to the largest accounts.
Creator identity was also common among younger respondents: 45% of Gen Z and Millennial respondents considered themselves creators or influencers. Among Gen Z purchase-decision factors, influencer recommendations ranked at 9%, compared with 7% for recommendations from friends and family in the reported measure. The figures come from HubSpot’s survey and its relevant sub-samples, so they should not be treated as a complete description of all generations or social platforms.
Community participation added another route for peer influence. Twenty-seven percent of social-media users reported actively engaging in an online community during the previous three months, while 28% followed virtual influencers. For brand content, 52% of consumers said funny brand-post content was the most relatable type on social media. Consumer Trends Report 2024
Customer advocacy program benchmarks
Influitive’s 2022 State of Customer Marketing Report surveyed customer-marketing practitioners, so these figures describe organizational reports and estimates rather than consumer behavior. Sixty-three percent said their organization had more customer advocates than the previous year, while 31% said the advocate count was about the same and 6% said it was lower. Respondents estimated that customer advocates represented 24% of their customer base on average.
The report also compared Influitive customers with non-customers. Influitive customers reported 14% more success growing customer advocates than non-customers. In addition, 42% of Influitive customers said they were considering, merging, or had merged customer advocacy and online-community programs, compared with 9% of non-Influitive customers.
Customer marketing was widely prioritized in the practitioner sample: 96% classified it as important or very important to their organization’s overall success. The reported 24% advocate-base figure is an estimate, not a standardized industry share, and the comparative findings are vendor-report results rather than an independent causal evaluation. 2022 State of Customer Marketing Report
Taken together, these benchmarks describe advocacy as a connected system: trust creates willingness to recommend, reviews make support visible, effective service creates reasons to speak positively, and creators or communities extend peer influence. Measurement remains most useful when each percentage is kept with its original population, geography, definition, and period.
