Word of Mouth Marketing Statistics 2026: Trust, Reviews and AI

49% of US consumers trust online reviews as much as personal recommendations from friends and family in 2026, according to BrightLocal. That is up from 42% in 2025 but down from 79% in 2020. Word of mouth is also moving to AI. 45% of US consumers used ChatGPT or similar tools for local business recommendations in 2026, up from 6% a year earlier.

Key statistics

Word of mouth marketing statistics

Word of mouth now runs through two channels. People still ask friends and family. They also read the experiences of strangers in online reviews, which work as word of mouth at scale.

Almost every US consumer now checks what other customers say. 97% read online reviews for local businesses in 2026, according to BrightLocal. The habit is getting stronger. The share who always read reviews rose from 29% to 41% in one year.

Reviews act in both directions. 85% are more likely to use a business after positive reviews. 77% are less likely after negative ones. Volume matters too. 47% will not use a business with fewer than 20 reviews.

Reviews start the journey more often than they end it. After a positive review, 54% go on to check the business's own website, up from 32% in 2019. Word of mouth earns the visit. The business still has to close the sale.

Trust in personal recommendations statistics

The most cited word of mouth numbers come from Nielsen's global trust survey. Its latest global edition dates from 2015. Newer data is US-only.

Recommendations from people we know remain the most trusted form of marketing in Nielsen's data. 83% of global respondents trusted friends and family in 2015. Online consumer opinions came third at 66%, behind branded websites at 70%.

The 17-point gap between friends and strangers online is the core of word of mouth. People trust reviews, but less than they trust someone they know.

Treat the 2015 figure with care. Nielsen has not published a newer global edition on its site. Many stats blogs still quote it as current. It is a decade old and should be read as a baseline, not today's level.

Online reviews vs word of mouth

BrightLocal has asked US consumers the same question for years. Do they trust online reviews as much as personal recommendations?

Trust in reviews has fallen a long way. 79% of US consumers trusted reviews as much as personal recommendations in 2020. By 2025 it was 42%. The 2026 edition shows a partial recovery to 49%.

Lower trust has not meant less use. 97% of US consumers still read reviews in 2026. Shoppers rely on reviews but rank them below a friend's advice. Concern about fake reviews, covered below, is one likely reason.

Our calculation puts the drop at 30 percentage points from 2020 to 2026. The 2020 and 2026 surveys use different panels of around 1,000 US adults, so small year-to-year moves are within normal survey noise. The long fall is too large to be noise.

Referral and recommendation statistics by channel

Recommendations do not work alone. Nielsen and Bazaarvoice show where they sit next to advertising, social media and creators.

Advertising reaches more people, but recommendations carry more trust. Nielsen found 45% of US new brand triers called advertising useful. 30% used recommendations and 18% used reviews. Recommendations were 1.7 times as common as reviews in those journeys.

Across six countries, Bazaarvoice found 52% of shoppers named real customer reviews as the biggest factor in a final purchase in 2025. Authenticity cuts both ways. 52% distrust creator content that feels overly promotional, and 44% are wary of overly positive, generic reviews. Our influencer marketing statistics page covers creator reach in more detail.

Word of mouth can be prompted. 78% of US consumers were asked for a review in the last 12 months, and 83% of those asked wrote one, by our calculation from BrightLocal data. Asking is the cheapest referral tactic a business has.

AI as the new word of mouth

Generative AI tools now summarise what other customers say. For many shoppers they are becoming the first place a recommendation comes from.

The biggest shift in 2026 is AI. 45% of US consumers used ChatGPT or similar tools for local recommendations, up from 6% in 2025. AI became the third most used source. Google fell from 83% to 71% but stays first.

By our calculation, AI tools now reach 63% as many consumers as Google does for local recommendations. A year earlier the figure was 7%. Trust is following use. 42% of US consumers trust AI platforms as much as traditional reviews.

AI also reshapes the reviews it summarises. 23% of review writers used AI at least sometimes in 2026, according to Bazaarvoice. 64% of consumers say AI-written reviews are not authentic, yet only 16% are very confident they could spot one. Our AI search statistics page tracks wider AI search use.

Fake reviews and the limits of online word of mouth

Online word of mouth only works if the reviews are real. The UK government commissioned the most detailed public estimate of fake reviews.

The UK Department for Business and Trade estimates that 11% to 15% of reviews in consumer electronics, home and kitchen, and sports and outdoors are fake. The model covered 2.1 million reviews on 9 popular UK platforms.

Well-written fakes work. Shoppers were 3.1% more likely to buy a product with subtle fake reviews, and 9.2% more likely when it cost over £80. Poorly written fakes backfired, cutting purchase likelihood by 5.3%. The estimated harm is £50 million to £312 million a year, and the authors call that conservative.

This helps explain the trust gap in the BrightLocal data. Consumers know some reviews are fake, so they discount strangers against friends.

How these sources measure word of mouth

No single source measures word of mouth directly. Each one captures a different part of it, with its own sample and limits.

BrightLocal surveys about 1,000 US adults each year through a SurveyMonkey panel. It asks about local businesses, not all purchases. The question wording on trust has changed slightly between editions, and the 2020 figure comes from the 2025 report's look-back.

Nielsen's 2015 global trust survey is the last global edition on its site, and the page does not state the sample size. Its 2022 US article draws on Commspoint Journey data and a US trust survey. Both are research firms' own data rather than official statistics.

Bazaarvoice is a review platform vendor, so it has an interest in showing reviews matter. Its 2025 report covered 8,000+ shoppers in six countries via Savanta. The March 2026 AI study covered 1,300+ adults and does not state a country on the release.

The Department for Business and Trade study is the only official source here. It combines a machine learning model with a 4,900-person shopping experiment. It covers products on e-commerce platforms, not services or local businesses.
