Brand Advocacy: How to Turn Customers and Employees Into Recommenders

Brand advocacy matters because recommendations beat advertising on trust: in Nielsen's 2021 Trust in Advertising study, 88% of respondents trusted recommendations from people they know more than any other channel. A brand cannot buy that trust; it can only earn it and help the people who give it. This guide explains who advocates are, how to grow their number and how to measure the result on Google, on social networks and in AI assistants.

What is brand advocacy?

Brand advocacy is any recommendation of a brand made of the advocate's own will: a customer telling a colleague which tool to choose, a review on a public platform, an employee sharing a product launch, a supplier recommending a partner. Three groups produce most of it:

• Customers: the largest group, and the most credible to other buyers. A satisfied customer who recommends you is the core of advocacy.
• Employees: they know the brand from the inside and their networks are much larger than the company's. LinkedIn reported in 2020 that employees have on average 10 times more connections than their company has followers on the network.
• Partners: resellers, integration partners, agencies and suppliers who recommend you because your success serves theirs.

Advocacy shows up in different places depending on the business:

• Consumer brands: reviews on product pages and marketplaces, posts and stories on Instagram or TikTok, recommendations between friends.
• B2B and software: peer recommendations in private conversations, reference calls during a sales cycle, reviews on software comparison sites, posts on LinkedIn.
• Local businesses: Google reviews, word of mouth in the neighborhood, local groups on social networks.
• Every sector: forum and community threads, where buyers ask which brand to choose and get unfiltered answers.

Advocacy is the visible result of brand loyalty: loyalty keeps a customer, advocacy brings new ones.

Brand advocates, ambassadors, influencers, referrers: what is the difference?

The terms overlap in everyday use, but the relationship with the brand is different in each case:

A healthy strategy uses advocacy as its base: ambassador and referral programs work best when they recruit people who were already advocates before any reward.

Why does brand advocacy matter?

• Trust: a recommendation from a peer answers the doubts that ads cannot.
• Reach: customers and employees reach networks that the brand account never reaches, which feeds brand awareness at no media cost.
• Cost: advocates are not paid, so each recommendation lowers the average cost of acquiring a customer.
• Content: reviews, posts, photos and answers in forums form a stock of user-generated content that keeps working after it is published.
• Search and AI visibility: that public content is what Google surfaces and what AI assistants read when they compare brands.

How do you build brand advocacy?

1. Deliver an experience worth talking about

No program creates advocates out of an average product. Find the moment where customers are surprised in a good way (speed, a result, support, a detail of the packaging) and make it systematic.

2. Identify your promoters

The Net Promoter Score, introduced by Fred Reichheld of Bain & Company in Harvard Business Review in December 2003, asks "How likely are you to recommend us to a friend or colleague?" on a scale of 0 to 10. Bain's method classifies 9 and 10 as promoters, 7 and 8 as passives, 0 to 6 as detractors. Your promoters are your future advocates: contact them first.

3. Make recommending easy

Send promoters a direct link to leave a review, a short text they can adapt, visuals they can share. Ask them for one specific action, not "talk about us". Published reviews then become social proof on your own pages.

4. Give advocates a place to meet

A user community, a forum, a private group or regular user events turn isolated fans into a group that answers newcomers' questions and creates content. Communities also reveal your most active members.

5. Involve employees, without forcing them

Employee advocacy works when people share what they are proud of. Give them news worth sharing, simple guidelines and freedom of tone, and help those who want to build their personal brand on LinkedIn. Forced posting of identical messages produces the opposite effect, and employees must make clear that they work for the company when they recommend it.

6. Recognize advocates without buying them

Thank them publicly, feature their stories, give early access to new features, invite them to an advisory group. Recognition keeps advocacy voluntary; cash for opinions turns it into advertising that must be disclosed.

7. Treat detractors as a priority

A detractor talks too. Answer negative reviews, solve the problem, and check whether the same complaint comes back: fixing it is often the fastest way to create new promoters.

How do you measure brand advocacy?

A worked example of the score: out of 200 respondents, 110 give 9 or 10 (55% promoters), 50 give 7 or 8 (25% passives) and 40 give 0 to 6 (20% detractors). The NPS is 55 minus 20, so +35. The score ranges from -100 to +100; compare it with your own past results and with companies in the same sector rather than with a universal benchmark.

Read these indicators together: a high NPS with few reviews means promoters exist but nobody asks them to speak, while many mentions with a falling NPS often signal a wave of complaints.

Which mistakes kill brand advocacy?

• Paying for opinions without saying so: a paid recommendation is advertising. In the United States, the FTC rule announced in 2024 also requires reviews written by managers or employees to disclose their link with the company.
• Scripted employee posts: twenty identical messages published the same morning look like a campaign, and networks treat them as one.
• Asking too early: requesting a review before the customer has used the product produces short, weak reviews, or none.
• Ignoring passives: customers who give 7 or 8 are close to becoming promoters; one improvement can tip them.
• Measuring only volume: a hundred mentions mean little if they are neutral or negative. Follow the tone as well, since it shapes brand perception.
• Forgetting the advocates once they have spoken: thank them, keep them informed and involve them in the next launch.

How does brand advocacy shape AI answers?

When someone asks ChatGPT, Gemini or Perplexity which brand to choose, the answer largely reflects what third parties write: reviews, comparisons, forum threads. Advocates produce exactly that content. Sorank's study of 301,025 AI answers shows that Reddit is cited in 1.48% of measured answers, and some models cite it much more than others. A brand that customers recommend in Reddit discussions gives AI assistants material to recommend it too.

This makes two measures useful. The first is AI brand mentions: is your brand named in answers about your category? The second is AI share of voice: how often you appear compared with competitors. Sorank, our product, tracks both with its AI mention tracking on ChatGPT, Claude and Gemini.

What to remember

Brand advocacy is earned through the experience, revealed by the Net Promoter Score and amplified when you make recommending easy. Start with your promoters, give employees reasons to be proud rather than scripts, answer detractors, and measure advocacy where it now shows up: reviews, social networks, search results and AI answers.
