Two businesses can rank in the exact same position on Google. One shows a plain blue link. The other shows star ratings, a price, and an FAQ dropdown, and gets the click.
That difference is schema markup: structured code that tells Google, and increasingly ChatGPT and Perplexity, exactly what's on your page. Done right, it earns you rich results and a real shot at being cited in AI-generated answers. Done halfway, it does nothing. Google ignores incomplete or inaccurate markup, and a lot of "schema implementation" out there is exactly that.
The foundation for most business sites: name, address, hours, service area, and the entity details that anchor everything else Google and AI systems know about your brand. This is also what supports a knowledge panel and stronger local search presence.
Star ratings, pricing, and availability shown directly in search results. This is the schema type with the most direct, visible impact on click-through rate for any business selling products or services online. (For sites without products to mark up, AggregateRating and Review schema can still apply to services; worth checking eligibility either way.)
Turns your existing Q&A content into expandable answers shown right in the search listing: visibility without the user even needing to click through.
Helps Google and AI systems understand who wrote your content and when, which increasingly factors into whether content gets surfaced in AI Overviews and treated as a credible source.
A smaller win individually, but it improves how your site's structure displays in search results and helps establish the entity relationships between your pages.
