About 4Linking
From the official readme · v4.6.146Description
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
Installation
- In your WordPress admin, go to Plugins → Add New and search for 4Linking, or upload the plugin ZIP under Plugins → Add New → Upload Plugin.

Frequently asked questions
Is 4Linking really free?
Yes. This version is completely free, fully functional and runs entirely on your server. There’s no account, no signup, no usage limit and no time limit.
Does 4Linking work with my SEO plugin (Yoast, Rank Math, etc.)?
Yes. 4Linking complements general SEO plugins rather than replacing them. Yoast and Rank Math handle analysis, meta tags and on-page SEO; 4Linking handles internal linking mechanics. Many users run both together without issues.
Will it touch links I added myself?
No. 4Linking only manages the links it creates from your rules. Your manual links are left untouched, and you can exclude any URL you don’t want it to act on.
Can I apply rules to posts I already published?
Yes. Besides linking new content as you publish, you can run a bulk pass that applies your active rules across existing posts.
Is 4Linking compatible with WooCommerce?
Yes. The plugin works alongside WooCommerce without conflicts and treats product pages like any other content type.
What happens to my data if I uninstall the plugin?
By default, uninstalling 4Linking removes its data: rules, pillar pages, exclusions, settings and the link map. There’s an option in the plugin settings to preserve your data on uninstall if you prefer.
Where do I get support?
Please use the WordPress.org support forum. Community support is provided there.
