NOFOLLOW LINK CHECKER – INSTANTLY IDENTIFY SEO LINK ATTRIBUTES
===============================================================


WHAT DOES THE EXTENSION DO?
---------------------------

Nofollow Link Checker is a practical browser extension designed for
website owners, SEO specialists, marketers, editors, developers,
and content managers.

After clicking the extension icon in the browser toolbar, the extension
scans the currently active page and highlights links with clear,
color-coded rectangular borders. This allows users to instantly
recognize important SEO-relevant link attributes and link types
directly within the live page context.

The extension visually distinguishes between different link
classifications, including:

- Nofollow links
- Dofollow internal links
- Dofollow external links
- Sponsored links
- UGC (User Generated Content) links
- Links containing multiple SEO rel attributes
- JavaScript-based links
- Mailto links
- Telephone links
- Anchor (in-page) links
- File download links
- Unsupported or non-standard links

This makes it significantly easier to review link markup, validate
link labeling, identify potential SEO issues, and understand how links
are presented and structured on real webpages.


COLOR CODING

WHO IS THE EXTENSION FOR?
-------------------------

Nofollow Link Checker is intended for anyone who needs to inspect or
monitor link attributes directly on live websites.

Typical use cases include:

- SEO professionals performing on-page link reviews
- Content managers validating affiliate and editorial links
- Outreach and link-building teams verifying placements
- Website owners auditing internal and external linking structures
- Developers and QA teams checking rendered links on modern
  web applications

The extension helps users quickly understand link behavior without
needing to inspect source code or run complex SEO tools.


WHAT ARE THE LIMITATIONS?
-------------------------

While Nofollow Link Checker improves link detection on many modern and
dynamically rendered websites, certain technical limitations remain.

For example:

- Links inside restricted or cross-origin iframes may not be accessible
  to the extension
- Some custom JavaScript interactions may not expose a real URL that
  can be classified
- Highly abstracted framework components can make link detection less
  reliable
- The extension provides visual classification of links but does not
  perform a full SEO audit, crawling simulation, or ranking analysis

Nofollow Link Checker is designed as a fast visual inspection tool to
support SEO workflows directly within the browser.
