SAN DIEGO shopping center websites.

Which centers. The 100 largest named shopping centers in San Diego County by footprint in OpenStreetMap, checked October 10, 2026. Car dealerships, single stores, hotels, and duplicates were removed before sampling, and two more were set aside during research because they are not multi-tenant retail centers; the next-largest centers took their place. That leaves 100 scored centers. OpenStreetMap does not list every center, and smaller neighborhood centers are outside this first edition.

Second look. Every center with no page found on the first pass was checked again, through the property lists of the owners and leasing brokerages active in the county and the center’s own domain names, before it was scored as having none.

What counts. Only pages published by the center, its owner, its property manager, or its leasing brokerage. Listing portals such as LoopNet and Crexi, map listings, and social media do not count. Each criterion was scored from what a visitor could see on the check date, with the page that showed it recorded as evidence.

Mobile speed. Google PageSpeed Insights on its mobile setting, the median of three runs per page, as in Orange County. Pages on large owner platforms share one design, so their scores reflect the platform.

Comparing counties. The Orange County figures come from our September 2026 review of 298 centers, narrowed to its 100 largest by the same footprint measure so the two samples match.

Corrections. Scores are a snapshot and a site can change the next day. We publish only medians, shares, and the names of the highest-scoring centers. Owners and managers can ask for their center’s scorecard or send a correction, and we re-check and date every change.
