Window and door installation companies compete for high-ticket projects ($5K-$50K+ per home) where homeowners research extensively before contacting contractors. Most window companies set up GBP once and never optimize, losing meaningful ranking to competitors. The optimization moves are systematic when you know what Google weights for this category.
Effective window and door GBP optimization centers on five factors. First, NAP consistency across GBP, website, and major directories (BBB, Angi, HomeAdvisor, Houzz — Houzz matters meaningfully for window/door because homeowners research aesthetics there). Second, primary category 'Window Installation Service' with secondaries: 'Door Supplier,' 'Window Supplier,' 'Sliding Door Shop,' 'Storm Window Installation Service.' If you carry specific brands (Pella, Andersen, Marvin, Renewal by Andersen), the brand affiliation matters for searches like 'Andersen windows [city].' Third, comprehensive photo library. Window and door installations are visual — GBPs with 75+ photos rank meaningfully higher. Upload completed installations, before/after pairs showing window replacement transformations, custom entry doors, and brand-specific products. Fourth, review velocity. Window/door customers leave detailed reviews when asked because the installation is a major project. Ask via text 24-72 hours post-completion. Fifth, website integration. Your GBP should point to a fast, mobile site with matching NAP, service-specific pages (replacement windows, entry doors, patio doors, storm doors), brand-specific pages, and embedded reviews. Weekly Google posts featuring recent installations and seasonal content (winter weatherization, summer energy efficiency) signal active business.
