About Dofollow & Nofollow Links Analyzer

The Dofollow & Nofollow Links Analyzer is an online tool that analyzes a single webpage URL and identifies all dofollow and nofollow links present on that page. It extracts anchor links directly from the page’s HTML, classifies them based on the rel attribute, and displays clear counts and detailed link information.

This tool helps users quickly understand the link structure of a webpage by separating dofollow and nofollow links in an organized and readable format.

What Is This Tool?

This tool allows users to:

  • Enter a webpage URL

  • Fetch the page content

  • Extract all anchor (<a>) links

  • Identify which links are dofollow and which are nofollow

  • View link counts and detailed lists

  • Export link data as a CSV file

The analysis is performed on a single webpage URL provided by the user.

What Are Dofollow and Nofollow Links?

Dofollow Links

Dofollow links are standard HTML links that do not contain the nofollow value in their rel attribute. These links are treated as normal links and are categorized as dofollow by the tool.

Nofollow Links

Nofollow links are links that contain the rel="nofollow" attribute.
This tool identifies a link as nofollow when the rel attribute includes the value nofollow (case-insensitive).

If the nofollow attribute is not present, the link is classified as dofollow.

How This Tool Works

The link analysis process follows these steps:

  1. URL Input

    • The user enters a webpage URL.

    • If the protocol is missing, the tool automatically adds https://.

  2. URL Validation

    • The backend validates the URL structure.

    • Invalid URLs are rejected with an error message.

  3. Fetch Page Content

    • The tool sends a request to the webpage using a browser-like user agent.

    • A timeout of 15 seconds is applied.

  4. HTML Parsing

    • The page HTML is parsed using an HTML parser.

    • All anchor tags (<a href="">) are extracted.

  5. Link Filtering

    • Links with javascript:, mailto:, or tel: are ignored.

  6. URL Normalization

    • Relative URLs are converted into absolute URLs using the page URL as the base.

  7. Link Classification

    • The tool checks the rel attribute of each link.

    • Links containing nofollow are marked as nofollow.

    • All other links are marked as dofollow.

  8. Results Generation

    • Links are counted, categorized, and returned to the frontend.

    • Results are displayed in tables and summary cards.

Nofollow & Dofollow Links Analyzer FAQs

Common questions about detecting and analyzing nofollow and dofollow links.

No. The tool analyzes only the single webpage URL that you enter. It does not crawl internal pages, subpages, or external links beyond the provided page.

The tool checks the rel attribute of each <a> tag.
If the rel attribute contains the value nofollow (case-insensitive), the link is marked as nofollow. Otherwise, it is treated as dofollow.

No. The tool skips links that start with:

  • javascript:

  • mailto:

  • tel:

Only valid web URLs with an href attribute are analyzed.

If a link uses a relative path such as /about, the tool automatically converts it into an absolute URL using the page’s base URL before displaying it.

If the protocol is missing, the tool automatically adds https:// before processing the request.

If the page cannot be fetched due to network issues, timeout, or request errors, the tool will display an error message such as:

“Failed to fetch URL”

A timeout of 15 seconds is applied to prevent long waits.

No. The tool fetches the page, processes it, and returns the results. There is no storage mechanism in the implementation.
