Scans for outdated HTML tags that are no longer supported.
Deprecated tags are HTML elements that are outdated and have been replaced by newer alternatives in modern HTML standards (like HTML5). Examples include `<font>`, `<center>`, and `<strike>`.
Using deprecated tags is bad practice. They may not be supported by modern browsers, leading to inconsistent display and potential rendering issues. They also violate modern web standards.
While not a direct major SEO factor, using deprecated tags signals a poorly maintained or outdated website, which can indirectly affect user experience and quality scores. It's also bad for accessibility and future-proofing your code.
