Optimize a Google Business Profile to win the local 3-pack

You are a local SEO specialist optimizing a Google Business Profile (GBP), not writing generic marketing copy. Google's own local-ranking guidance names three factors — relevance, distance, and prominence — and every recommendation below should point at one of those, not at vague "more visibility."

BUSINESS: Denver Rapid Plumbing
YOUR GUESS AT THE RIGHT PRIMARY CATEGORY: Plumber
SERVICES OR PRODUCTS OFFERED: emergency pipe repair, water heater installation, drain cleaning
LOCATION / SERVICE AREA: service-area business, no walk-in storefront, covers Denver metro within a 25-mile radius
TARGET LOCAL SEARCH TERMS: 24 hour plumber near me, emergency plumber Denver, burst pipe repair Denver
WHAT COMPETITORS' PROFILES DO DIFFERENTLY: top-ranking competitor lists both "Plumber" and "Drainage Service" and posts weekly

TASK

1. PRIMARY CATEGORY: GBP allows exactly one primary category plus up to 9 secondary categories. Recommend the primary category. If a plausible alternative exists, name it and explain the specific detail that settles the choice in favor of your pick — category match is one of the most heavily weighted relevance signals for "near me" and service-type queries, ahead of nearly every other profile field. Then list up to 9 relevant secondary categories.
2. BUSINESS DESCRIPTION: Write one under the 750-character limit. Put the core service and the location in the first ~250 characters — that's roughly what shows before a visitor has to tap "more." No URLs, no phone numbers, no prices, no superlatives ("best," "#1"), no limited-time offers — Google's guidelines reject or hide descriptions that read as an ad instead of a description.
3. Q&A SEEDING: The Q&A section is public and editable by any Google user, including competitors — an unanswered or wrongly-answered question sits there hurting conversion until someone corrects it. Write 5 self-seeded Q&A pairs covering the highest-friction real questions a buyer would have before contacting Denver Rapid Plumbing.
4. REVIEW RESPONSE TEMPLATES: Draft one template for a 5-star review and one for a 3-star-or-below review. Each should sound like a real owner, not a script — naturally mention the specific service and location without stuffing either in, and never offer compensation for a changed or removed review, which violates Google's review policies and risks profile suspension.
5. POST IDEAS: Suggest 3 Google Posts (What's New / Offer / Event style) tied to emergency pipe repair, water heater installation, drain cleaning, each under 1,500 characters with one clear next step.
6. NAP FLAG: Note anything in the inputs above that looks likely to create a Name/Address/Phone mismatch against how this business is probably already listed elsewhere (directories, the website footer) — inconsistent NAP undermines the "prominence" signal even when the profile itself is fully optimized.
