Internal Linking Related Contents The continuous creation of high-quality content is only half the battle in modern SEO. The real, often tedious, work lies in the time-consuming manual process of linking related articles to distribute “link juice,” improve topical authority, and keep users on your site longer. This process is prone to human error, missed linking opportunities, and is, quite frankly, a massive time sink for high-volume content creators.
Enter Internal Linking Related Contents, a specialized WordPress plugin that promises to automate this essential SEO task. Its appearance on AppSumo as a Lifetime Deal (LTD) offers a tantalizing solution: a low-cost, set-it-and-forget-it automation tool that solves a critical, recurring workflow problem. In this in-depth review, we dissect its value and performance.

First Impressions & Installation/UX
As a seasoned SaaS reviewer, I look for tools that solve a big problem with minimal fuss. Internal Linking Related Contents immediately delivers on simplicity.
- Installation/UX: The entire process is native to the WordPress dashboard. Installation is via the standard plugin upload, and the settings menu integrates seamlessly under the primary “Settings” or a dedicated, clearly labeled menu item.

Key Automation Highlight
The moment of immediate value came upon activation. Instead of requiring a lengthy indexation process, the plugin instantly scanned and suggested relevant links for all existing posts based on my site’s content. This immediate, retroactive linking improvement is a powerful demonstration of value that saves potentially hundreds of hours of manual work on an established blog.
Deep Dive into Core Features (Hands-On Analysis)

A good internal linking tool must be more than just a random link generator; it needs an intelligent algorithm. Here is the analysis of Internal Linking Related Contents’ core features.
| Feature | Description & Performance Analysis |
| Contextual Relevance Algorithm | This is the core engine. It analyzes post text, tags, and categories to match content, focusing on topical similarity. Performance: High. It consistently avoided surface-level keyword matching, instead prioritizing deeper topical connections. |
| Automated Post/Page Insertion | The flexibility in how links are displayed is critical. Options include: In-content block (after the second paragraph, for example), End-of-Post list (the classic “Related Articles”), and Widget/Shortcode placement. Performance: Excellent customization. The in-content block is clean and doesn’t disrupt the flow, crucial for user experience. |
| Exclusion/Inclusion Rules | For larger sites, control is paramount. The plugin allows for whitelisting or blacklisting specific Categories, Tags, or even individual Post IDs. Performance: Reliable. Crucial for excluding “pillar pages” from receiving too many outbound links or ensuring “evergreen content” always links to “money pages.” |
| Anchor Text Customization | While it automatically generates anchor text from the post title, users can override this with a custom list of relevant, keyword-rich anchor texts for specific suggested links. Performance: Adequate. This gives granular control to SEOs who prefer specific, targeted anchor texts over the automated title. |
Hands-On Test Case (MANDATORY)
To test the Contextual Relevance feature, I performed the following:
- I wrote a new, high-level post titled “Why Advanced Backlink Strategies Are Failing in 2025.”
- I asked the plugin to automatically suggest and insert 5 related links at the bottom of the article.
- The plugin accurately selected 5 older posts that discussed “link building tools,” “technical SEO audits,” and “content decay analysis.”
Outcome and Analysis: The plugin successfully avoided irrelevant articles about local SEO, social media marketing, or basic beginner guides. The placement was automatically created as a clean, bulleted list widget at the bottom of the article. The automation worked perfectly, showing a strong ability to understand content themes rather than just keyword proximity.
