LinkBoostr

Smart internal linking assistant that finds link opportunities in existing content and helps new pages rank faster—safely and effortlessly.

04Code

<p><strong>4Linking</strong> 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.</p>
<p><span class="embed-youtube" style="text-align:center; display: block;"><iframe loading="lazy" class="youtube-player" width="750" height="422" src="https://www.youtube.com/embed/qxHGYREUh18?version=3&rel=1&showsearch=0&showinfo=1&iv_load_policy=1&fs=1&hl=en-US&autohide=2&wmode=transparent" allowfullscreen="true" style="border:0;" sandbox="allow-scripts allow-same-origin allow-popups allow-presentation allow-popups-to-escape-sandbox"></iframe></span></p>
<p>4Linking is built around a simple, controllable idea: <strong>rules</strong>. 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.</p>
<h4>Key features</h4>
<ul>
<li><strong>Rule-based internal linking</strong> — 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.</li>
<li><strong>Pillar pages</strong> — mark your strategic pages so related content sends them preferential internal links, reinforcing your most important URLs.</li>
<li><strong>Visual link map</strong> — see how internal links are distributed across your site at a glance, with totals per rule and per page.</li>
<li><strong>URL exclusions</strong> — keep specific URLs (legal pages, login, checkout…) out of internal linking entirely, so links only land where you want them.</li>
<li><strong>Synonyms and variations</strong> — a rule can match a keyword and its variations, so natural writing still triggers the right links.</li>
<li><strong>Bulk processing</strong> — apply your rules across existing posts in one pass, not just on new content.</li>
<li><strong>Block editor and Classic editor</strong> — works with both, no setup friction.</li>
<li><strong>Runs entirely on your server</strong> — no external services, no account, no signup. Your content never leaves your site.</li>
</ul>
<h4>Who it’s for</h4>
<ul>
<li><strong>Bloggers and site owners</strong> who want a tidy internal link structure without editing every post by hand.</li>
<li><strong>Online editors and media sites</strong> publishing daily, who need internal architecture to scale without becoming a full-time job.</li>
<li><strong>SEO agencies and content teams</strong> that need to apply consistent linking rules reliably across one site or many.</li>
</ul>
<h4>Why 4Linking</h4>
<p>There are many SEO plugins, and they all have their place. 4Linking does one job well: <strong>serious internal linking, with full control</strong>.</p>
<ul>
<li><strong>Alongside your SEO plugin (Yoast, Rank Math)</strong> — those handle analysis and on-page SEO; 4Linking handles the actual mechanics of internal linking. They complement each other.</li>
<li><strong>Versus manual linking</strong> — no more opening old posts to add links by hand. Define a rule once and it applies everywhere, including posts you publish later.</li>
<li><strong>Versus guesswork</strong> — every link follows an explicit rule you wrote, so you always know why a link exists and where it points.</li>
</ul>
<h4>Privacy and data</h4>
<p>4Linking runs <strong>entirely on your own server</strong>, using WordPress’s standard database and APIs. It makes <strong>no calls to any external service</strong>, requires no account and collects no data. Your content stays on your site.</p>
<h4>Looking for AI content and semantic linking?</h4>
<p>4Linking has a separate commercial version, <strong>4Linking PRO</strong>, available at <a href="https://4linking.com/en/" rel="nofollow ugc">4linking.com</a>. 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.</p>
<h4>Requirements</h4>
<ul>
<li>WordPress 6.0 or higher</li>
<li>PHP 7.4 or higher</li>
</ul>
