4Linking vs Interlinks Manager – Internal Links Optimizer

4Linking automates internal linking in WordPress. You define the rules once — which keywords link to which pages — and the plugin keeps your internal link structure clean and consistent across the whole site, from a small blog to an editorial site with thousands of posts, without the manual work internal linking usually requires. 4Linking is built around a simple, controllable idea: rules. Instead of guessing or linking by hand, you tell the plugin how your content should connect — and it applies those relationships automatically as you publish. Key features Rule-based internal linking — decide which keywords link to which URLs, with custom anchor text, frequency caps and priority. You stay in full control of every link the plugin creates. Pillar pages — mark your strategic pages so related content sends them preferential internal links, reinforcing your most important URLs. Visual link map — see how internal links are distributed across your site at a glance, with totals per rule and per page. URL exclusions — keep specific URLs (legal pages, login, checkout…) out of internal linking entirely, so links only land where you want them. Synonyms and variations — a rule can match a keyword and its variations, so natural writing still triggers the right links. Bulk processing — apply your rules across existing posts in one pass, not just on new content. Block editor and Classic editor — works with both, no setup friction. Runs entirely on your server — no external services, no account, no signup. Your content never leaves your site. Who it’s for Bloggers and site owners who want a tidy internal link structure without editing every post by hand. Online editors and media sites publishing daily, who need internal architecture to scale without becoming a full-time job. SEO agencies and content teams that need to apply consistent linking rules reliably across one site or many. Why 4Linking There are many SEO plugins, and they all have their place. 4Linking does one job well: serious internal linking, with full control. Alongside your SEO plugin (Yoast, Rank Math) — those handle analysis and on-page SEO; 4Linking handles the actual mechanics of internal linking. They complement each other. Versus manual linking — no more opening old posts to add links by hand. Define a rule once and it applies everywhere, including posts you publish later. Versus guesswork — every link follows an explicit rule you wrote, so you always know why a link exists and where it points. Privacy and data 4Linking runs entirely on your own server, using WordPress’s standard database and APIs. It makes no calls to any external service, requires no account and collects no data. Your content stays on your site. Looking for AI content and semantic linking? 4Linking has a separate commercial version, 4Linking PRO, available at 4linking.com. It adds AI article generation, semantic internal linking, knowledge bases, AI image generation, translation and automation pipelines. PRO is a separate product — this free plugin is fully functional on its own and is not time-limited or feature-gated in any way. Requirements WordPress 6.0 or higher PHP 7.4 or higher

Interlinks Manager is an SEO WordPress plugin that gives you the ability to monitor and optimize your internal links.

The ability to import and export plugin data and settings to back up configurations or quickly set up the plugin on multiple websites. Monitor your internal links Keep track of all the internal links available in your articles with the Dashboard menu. Here you will find a list of your articles along with internal link data retrieved by the plugin, such as the current number of internal links, the recommended number of internal links, the inbound links received, and the optimization status. The Filter & Sort section included in this menu will allow you to search through this data, filter them, or sort the data based on specific criteria. For example, you can use this section to find all the non-optimized articles and work on their optimization. Calculate the link equity Visit the Link Equity menu to receive an estimate of the link equity for all the URLs linked in your articles. Use the information available in this menu to improve the distribution of link equity, empower your cornerstone articles, or improve the SEO performance of your product pages. Optimize the number of internal links Receive information about the optimization status of the internal links while you edit an article with the Internal Links Optimization panel. This panel provides information on how to optimize the article’s internal links. For example, you will receive messages like “The number of internal links in this post is within the recommended range.” or “The number of internal links should be between 4 and 6”, etc. Find Broken Links and Redirects Analyze the HTTP response of your internal links to detect issues affecting your site. Identify links that lead to unavailable pages, redirects, or other HTTP status issues. Customize the plugin behavior Configure the internal links optimization algorithm Change the values of the Characters per Interlink and the Optimization Delta options to modify the results generated by the algorithm used to measure the optimization status of the articles. Customize the algorithm used to calculate the link equity Use the options in the Link Equity section of the plugin options to customize the calculation of the link equity. For instance, you can set default Total Link Equity of all the pages, set a custom Position Penalty, aggregate the link equity of URLs with different anchors, aggregate the link equity of the URLs with parameters. Configure the PHP memory, the maximum execution time, and the analyzed post types If your website has many articles, you have options that control the technical aspects of the plugin’s analysis in the Analysis section. For example, you can set a custom PHP memory size and increase the maximum execution time with the script used by the plugin, limit the number of analyzed articles, restrict the analysis to specific post types, and more. These options help support larger websites, including those with 100k+ posts. Enable the plugin editor panels only on specific post types You can use the options in the Editor Panels to display or hide the Internal Links Settings and the Internal Links Optimization panels only with specific post types. Assign a custom total link equity to specific posts The plugin allows you to assign each article a parameter used to calculate the link equity named Total Link Equity. Configure this constant with a realistic value to improve the accuracy of the link equity.
