Understanding and implementing relative URLs is a crucial aspect of SEO, as they enhance user experience, improve site navigation, and boost search engine crawler efficiency. The ies rule, part of the relative URL standard, allows you to specify a base URL, making your site's URLs more dynamic and manageable.

The basic syntax of the ies rule involves using the <base> tag within the <head> section of your HTML document. The <base> tag specifies the base URL to be used for all relative URLs on that page. For example:

Implementing the <base> Tag
Suppose you set the base URL as follows:

```html
All relative URLs like /about.html and /contact.html will be resolved to the full URLs https://www.example.com/pages/about.html and https://www.example.com/pages/contact.html, respectively.
SEO Benefits of the <base> Tag
The <base> tag offers several SEO advantages:

Cleaner URL Structures
