What are SEO blocks?

SEO blocks are structured content sections or modules on a webpage designed to improve optimization. They may include headings, text, images, or metadata arranged to highlight important information for both users and search engines. Some platforms use SEO blocks to describe editable areas where keywords, links, and schema can be applied. Their function is to ensure that every part of a webpage contributes to stronger indexing, clarity, and user engagement. Organized blocks help make content easier to scan and more effective in ranking.
