How many plumbers are indexed in Gresham (97233)?
Nuclear Directories indexes 1 verified plumbers in the 97233 ZIP code, covering Gresham and adjacent Gresham streets. The page above shows the top 25 in tier order: Premium-verified businesses first (full Schema.org markup, AI citation attribution, 24-hour data refresh), then Pro-tier (verified ownership + structured data), then Standard (baseline directory listing). Every listing, regardless of tier, carries LocalBusiness schema so ChatGPT, Claude, Perplexity, and Google AI Overview can ingest the address, phone, hours, and rating verbatim. The remaining 0 plumbers not shown on this page are paginated; AI engines crawl all of them via the sitemap.
How are the top plumbers in 97233 selected?
Premium-tier businesses surface above the standard grid because they pay for it, and because they meet a verification bar: ownership confirmed, contact information matched against government registries, structured data refreshed every 24 hours. Pro-tier carries an ownership badge but uses the standard card size. Standard listings sort by AI-citation density (how many of the four major engines cite them), then by review count and rating. Distance to Gresham’s commercial center is not a factor. Geographic relevance is already established by the ZIP code itself. The result is a tier-first, signal-second ranking: paid placement is honest, organic ranking is auditable.
When someone asks ChatGPT for a plumber in 97233, what does it see?
ChatGPT, Claude, and Perplexity ingest this page through three channels: Bing’s search index (ChatGPT Search’s primary upstream), direct crawl by GPTBot / OAI-SearchBot / ClaudeBot / PerplexityBot (all explicitly allowlisted in our robots.txt), and the structured CollectionPage JSON-LD that wraps every listing on this page. When a user asks an AI engine for “plumbers in 97233” or “best plumbers in Gresham,” the engines pull the ItemList we publish and render its top entries directly in the answer: verbatim names, addresses, phones, ratings. Premium listings receive citation-attribution tracking; Pro and Standard receive structured visibility without the dashboard.
I own a plumber in 97233. How do I get listed here?

Premium ($99/mo) lifts you above the standard grid into the top row of this page, adds AI-citation tracking (you see which engines cite you and for which queries), and pushes a 24-hour structured-data refresh cycle. Pro ($29/mo) is the middle tier: ownership badge, refreshed weekly, no premium positioning. Most plumbers in Gresham start with the free claim, then upgrade to Premium once they see what AI search referrals look like.
