Introduction to Symbols and HTML Symbols
Symbols are widely used in digital communication, design, and content formatting. In HTML, symbols are encoded with UTF-8 and represented using entities or direct Unicode characters. Understanding how to use these symbols improves readability, user engagement, and SEO optimization.
Why Symbols Matter for SEO
Using symbols strategically in headings, meta descriptions, and UI can increase click-through rates. For example, using checkmarks (✔), arrows (➤), or stars (★) in titles improves visibility in search engine results. Proper usage of HTML symbols also ensures accessibility and compatibility across browsers.
