Real estate SEO has a delayed feedback loop. You publish a neighborhood guide in March, and you won't know whether it's working until June or July — if you're tracking rankings at all. That delay means most agents accumulate several mistakes simultaneously before any single one gets diagnosed.
The other challenge is that real estate websites look functional on the surface. IDX feeds pull in listings. Contact forms work. The site loads. But functional and optimized are not the same thing, and Google distinguishes between them at a granular level.
Below, we've organized the most common mistakes by where they occur in your SEO system — technical infrastructure, content, local signals, and authority. Understanding the category helps you prioritize fixes, because there's no point building links to a page that Google has partially deindexed due to duplicate content issues.
One important framing note: these are general patterns observed across agent websites. Your specific situation may differ by market size, brokerage platform, and how long your site has been live. Treat this as a diagnostic framework, not a universal prescription.
