Subscription-like service businesses with weekly/monthly visits, 52 weeks a year. Pest Control sits here too (Chapter 1). The review strategy: ask once a year, not every visit.
Pet waste is intimate-trust service — customers trust you in their backyard, weekly, often while they're at work. The relationship is built on consistency and discretion. The review story that matters: "They show up every week, even when it rains." Ask once a year, not every visit, and frame around the year of reliability rather than any single scoop.
House cleaning is trust-in-your-absence service — customers hand over a key and expect strangers in their home to do the job right without supervision. Reviews revolve around trust, consistency, and attention to detail. Framework: ask for a review after the 3rd clean, not the first — that's when customers feel confident enough to vouch. Ask again at the 1-year mark.
