Search engine optimization — SEO — is the practice of making your website appear when someone types a relevant question or phrase into Google. For a real estate agent, those phrases look like: "best buyers agent in [city]", "homes for sale in [neighborhood]", or "how to sell my house in [metro area]."
Google decides which pages to show based on three broad signals: relevance (does your page actually answer the query?), authority (do other credible sites link to you?), and experience (does your site load fast, work on mobile, and feel trustworthy?).
Real estate SEO is the process of improving all three — so your site ranks higher than a competitor's when a motivated buyer or seller runs that search.
It also includes your Google Business Profile (the map listing that appears when someone searches "realtor near me"), which operates on a slightly different set of ranking signals than your website but is equally important for local visibility.
What SEO is not: it is not a one-time fix, it is not buying Google Ads (that's paid search, or PPC), and it is not simply adding keywords to your homepage and waiting. Effective real estate SEO is an ongoing process that compounds over time — the longer you invest in it, the harder it becomes for competitors to displace you.
