Frequently asked questions

When should customers be asked for reviews?

At demonstrated success — milestones achieved, renewals confirmed, support brilliantly resolved — never at calendar intervals or immediately post-purchase. Behavioral willingness signals (retention tenure, engagement depth, NPS promoters) qualify better than tenure alone. Asking unhappy customers damages more than silence.

One well-timed ask outperforms ten scheduled ones; protect the ratio fiercely.

How do B2B reference programs work?

Through reciprocity and recognition: satisfied accounts invited personally (never automated cold), reference activity tracked against deals influenced, advocates recognized visibly (events, advisory boards, early access). Reference burnout is real — cap requests per advocate annually and rotate the pool deliberately.

Track reference-influenced pipeline; programs failing attribution lose executive sponsorship.

Should advocacy be incentivized?

For transactional advocacy (reviews, referrals), tested incentives accelerate measurably; for relationship advocacy (references, community leadership), recognition outperforms cash — advocates referring for money cheapen their own endorsement. Test both against holdouts measuring quality as well as quantity.

Thank every advocate personally regardless of outcome; gratitude sustains programs rewards cannot.

How do you handle negative reviews from email asks?

As service recovery intelligence: respond publicly with accountability, resolve privately with urgency, and feed causes into product and operations backlogs. Negative reviews from poorly timed asks indict targeting, not products — detractor suppression prevents most. Never incentivize positive reviews deceptively; platform penalties exceed any short-term rating gains.

Review response times publicly signal service quality to future buyers reading threads.

What is the difference between advocacy and referrals?

Advocacy builds public proof (reviews, references, testimonials, community leadership); referrals generate introductions (shared links, warm emails, affiliate mechanics). Advocacy compounds brand equity slowly; referrals create pipeline directly. Programs need both tracks with shared identification but distinct journeys and metrics.

Measure advocacy in assets and influence, referrals in introductions and conversions — never blend the dashboards.

How do you measure advocacy ROI?

Influenced pipeline (deals touching advocate assets), review-driven conversion lift, reference-attached win rates, and community-sourced retention — each against holdouts with program costs netted. Vanity metrics (NPS scores, review counts) flatter programs whose assets never influence deals. Attribute honestly; organic advocacy predates every program.

Report cost per influenced dollar beside program spend; advocacy must earn its budget like any channel.
