tag questions

The `<meta>` tag in HTML provides metadata about the document, such as character set, viewport settings, and SEO information. Common attributes include `charset`, `name`, `content`, and `http-equiv`. Meta tags play a crucial role in optimizing a web page for search engines and ensuring proper rendering across different devices.

Next.js offers several benefits for server-side rendering (SSR), including improved performance, SEO, and initial load times. SSR generates HTML on the server for each request, ensuring that search engines can easily index the content. It also reduces the time to first meaningful paint, providing a better user experience.

The `<link>` tag in HTML is used to define a relationship between the current document and an external resource. Common attributes include `rel`, which specifies the relationship type (e.g., `stylesheet` for linking CSS files), `href` for the URL of the resource, and `type` for the MIME type. The `<link>` tag is essential for including external stylesheets and other resources.

The `strip_tags()` function in PHP removes HTML and PHP tags from a string. For example: `strip_tags('<p>Hello</p>');` will return `'Hello'`. This function is useful for sanitizing user input by removing unwanted tags and preventing potential security risks, such as cross-site scripting (XSS) attacks. It is often used when displaying user-generated content.

A canonical tag is an HTML element used to indicate the preferred version of a webpage when there are multiple pages with similar or duplicate content. By specifying a canonical URL, you tell search engines which version of the page should be considered the authoritative source. This helps prevent duplicate content issues and consolidates ranking signals, ensuring that the preferred page receives the full benefit of inbound links and improves overall SEO performance.
