DESCRIPTION

Linkify is a powerful WordPress plugin that helps you generate and manage internal links throughout your website, enhancing your SEO performance and improving user navigation.

Creating internal links manually is time-consuming. Linkify automates this process by analyzing your content and generating contextual links, table of contents, breadcrumbs, and related content sections that improve your site structure and keep visitors engaged longer.

USAGE

Once the plugin is uploaded and activated:

  1. Navigate to Linkify in the WordPress admin menu

  2. Enable the features you want to use (Breadcrumbs, Table of Contents, Contextual Links, Related Content)

  3. Customize settings for each feature

  4. Your content will automatically be enhanced with the selected linking features

Here are the steps to get started with Linkify:

  1. Go to Linkify > Options to configure which post types should be supported

  2. Enable the features you want to use from the dashboard

  3. Adjust feature-specific settings like keyword threshold for contextual links

  4. Clear or regenerate the cache when making significant changes

Note: The plugin analyzes your existing content to create relevant internal links. No content is modified directly in your database.
