Highlight Links Plugin is a browser extension designed to help users easily identify different types of links on web pages. By using a color-coding system, the plugin makes it simple to spot the nature of each link, providing greater insight into web page content. The plugin applies a color-coding system to distinguish between various types of links:

• Dofollow links: These links are standard links that allow search engines to follow and index them. They are outlined in green.
• Nofollow links: These links instruct search engines not to follow or index them. They are outlined in red.
• UGC links: Links marked with the ugc attribute, typically used for user-generated content, are outlined in blue.
• Sponsored links: Links marked with the sponsored attribute are associated with paid content and are outlined in orange.
• Neutral links: These links have attributes like noopener or noreferrer, indicating they don’t pass referrer information. They are outlined in light gray.
• Javascript links: Links that begin with javascript: or have an empty href attribute are outlined in gray.

Links that are not recognized or colored by the plugin:

• Links without an href attribute or with javascript: URLs may be missed in certain scenarios.
• Links that do not include rel attributes are considered neutral and may not receive a specific color.
• The plugin does not highlight links that are dynamically generated by JavaScript after the page load unless manually triggered.

The plugin is a valuable tool for web developers, SEO professionals, and anyone interested in better understanding the types of links on a webpage. It is designed to provide a clear and efficient way to identify the relationships between pages, making browsing and analysis more transparent.
