Schema markup is the easiest SEO win you're not doing
Most agency clients have zero structured data on their websites. Adding schema markup takes 30–60 minutes per site and immediately improves how search engines understand and display the site. It's the highest-impact, lowest-effort SEO task you can offer.
What schema markup does
Schema markup is code (JSON-LD format) that you add to web pages to tell search engines exactly what the content represents. Without it, Google guesses what your page is about by parsing the HTML. With it, you're telling Google explicitly: "This is a dental practice at 123 Main Street, open Monday through Friday, with a 4.8 star rating."
The result: rich snippets in search results — star ratings, business hours, FAQ dropdowns, product prices, and more. Pages with rich snippets get 20–30% more clicks than plain blue links at the same ranking position.
