LinkerFlow

LinkerFlow builds smart, contextual internal links between your posts and pages, automatically. Better internal linking is one of the highest-leverage SEO wins on any site: it spreads link authority across your content, helps search engines discover and rank your pages, and keeps visitors reading longer. LinkerFlow handles it for you, based on a keyword configuration you control.

Why internal linking matters

• Rank higher. Contextual internal links pass authority to the pages you want to rank and help search engines understand your site structure.
• Keep visitors longer. Relevant links between related articles lower bounce rate and increase page views.
• Save hours. No more manually hunting for linking opportunities across hundreds of posts. LinkerFlow finds and places them for you.

What LinkerFlow does

• Automated contextual links placed inside your existing content.
• Smart keyword configuration so you decide which terms link to which target pages.
• Works on your live content through authenticated REST endpoints, applying links on top of the current post so your editor changes are preserved.
• Page builder support for Elementor and Divi: links are written back into the originating text widget or module without touching the rest of your layout.
• Multilingual ready with Polylang and WPML, so each language is linked correctly.
• SEO plugin aware, reading meta descriptions from Yoast SEO or Rank Math when available.
• Clean and lightweight: no public “powered by” credit links, no third-party scripts, styles, or tracking pixels loaded on your site.

How it works

Install the plugin, connect your site from WP Admin in one click, and configure your keywords in the LinkerFlow application. LinkerFlow then reads your published content and publishes approved internal links through this plugin, using WordPress’ native update flow so revisions are kept when enabled.

Technical overview

The LinkerFlow WordPress plugin connects your WordPress site to the LinkerFlow service for internal-link management. After you approve the connection, the LinkerFlow service can read published posts, pages, selected public custom post types, permalinks, language information, and post content through authenticated REST API endpoints.

The LinkerFlow service can also update post content through this plugin to publish approved internal links. Updates use WordPress’ native post update flow, so revisions are created when revisions are enabled for the post type.

This plugin does not add public-facing credits or links to your site. It does not load third-party scripts or styles. It does not read WordPress users, passwords, comments, private posts, drafts, settings, or unrelated plugin data.

External service

This plugin connects to the LinkerFlow software-as-a-service application operated at https://www.linkerflow.io and https://app.linkerflow.io.

The plugin requires a LinkerFlow account and an active LinkerFlow service plan to provide internal-link management. The GPL license applies to this WordPress plugin’s source code, not to the separately operated LinkerFlow SaaS application or service plan.

The site owner initiates the connection from WP Admin. During connection, the plugin redirects the browser to the LinkerFlow application with the site URL, a one-time nonce, and a state token. The LinkerFlow application then confirms the connection by sending the nonce and a generated shared secret to this site’s REST API. After connection, the LinkerFlow service uses that secret to authenticate future API requests.

Data sent to or accessed by the LinkerFlow service may include:

• Site URL.
• Published post, page, and selected public custom post type titles.
• Published content from post_content.
• Permalinks.
• Post type, publication status, modified date, and language information.
• Updated post content when approved internal links are published.

The service terms are available at https://www.linkerflow.io/terms. The privacy policy is available at https://www.linkerflow.io/privacy.
