SEO content schema refers to the structured data markup that is added to a website's HTML code to help search engines understand the content and context of the website. Schema markup is a code (semantic vocabulary) that is added to the HTML of a webpage to provide information about the page in a format that search engines can understand and use to display rich results in the search engine results pages (SERP).
Using schema markup, website owners can provide additional information about their pages, such as the types of products or services offered, reviews, and even events. This can help search engines to understand the context of the page, making it more likely to appear in relevant search results.
In addition to helping search engines understand the context of a page, schema markup can also be used to display rich snippets in the search engine results pages (SERPs), such as reviews, images, and prices. These rich snippets can help to increase the visibility and click-through rate of a website's search listings, making it more likely that users will click through to the website.
It's important to note that, while schema markup can be a valuable addition to a website's SEO efforts, it should not be the only tactic used. A well-optimized website with high-quality, relevant, and valuable content is crucial for good SEO performance.
