Commercial real estate SEO has four structural facts that residential SEO programs do not encounter.
Commercial brokerage is not residential brokerage at scale. The data layer, the directories, the buyer, and the queries diverge enough that a residential SEO program ports to commercial poorly. The commercial surface is its own vertical and the work is built against the commercial data layer directly.
Residential MLS architecture does not carry commercial inventory. Local MLSs and RESO Web API feeds carry residential listings. Commercial inventory lives on CoStar (subscription-walled), LoopNet (the CoStar-owned public surface), Crexi, and broker-direct platforms. The IDX duplicate-content problem that defines residential SEO does not apply, because the feed source is structurally different. Commercial SEO programs that route through residential IDX vendors miss the actual data layer entirely.
CoStar and LoopNet are the directory tollbooths for commercial. CoStar Group owns LoopNet, Apartments.com, and a dominant share of commercial inventory data. Commercial directory authority concentrates differently than residential. The independent-organic versus directory-tollbooth question still applies, but the directories are different and the entity-authority workaround runs on commercial practice areas (tenant rep, investment sales, asset classes) instead of buyer-representation content.
Commercial schema runs on practice-area specialization. RealEstateAgent is the same schema type for commercial. The differentiation comes through knowsAbout populated for commercial practice areas (office leasing, industrial sales, retail tenant rep, multifamily investment, 1031 exchange specialist) and areaServed mapped to the metropolitan statistical area where the broker actually transacts. Service nodes ship per practice area, not per geography alone.
Buyer is institutional or principal, not consumer. The commercial buyer is a corporate tenant, a syndication sponsor, an institutional investor, or a principal. Search intent skews toward asset-class research, market reports, comparable-sale data, and tenant-rep capability. The conversion shape is longer, the deal sizes are larger, and the content cadence runs against quarterly market reports rather than weekly buyer-education posts.
