NexLink

NexLink is a complete internal link management plugin for WordPress. It helps you automate keyword-to-URL linking, discover link opportunities, analyse your link structure, and insert suggestions directly in the editor — with no external service required.

Auto Linking

• Create up to 25 keyword-to-URL rules from the Auto Links manager
• Add up to 3 anchor text variations per keyword rule
• Set a per-post link limit and a site-wide limit per rule
• Filter rules to specific post categories
• Enable automatic linking when other post titles appear in your content
• Enable automatic linking when H2–H6 headings from other posts appear in your content
• Keyword blacklist — one phrase per line to permanently exclude terms from linking
• Import and export all keyword rules as CSV
• Post types supported: Posts, Pages, WooCommerce Products

Link Suggestions in the Editor

Classic Editor: A meta-box widget appears in every post and page editor. It shows relevant suggestions with relevance scores, lets you dismiss individual suggestions, and inserts links with your configured link prefix.

Block Editor (Gutenberg): Two widgets are available in the block editor:

• Sidebar panel — appears in the block editor sidebar with a real-time suggestion list, link format selection, and dismiss controls
• Document settings panel — appears in the Document tab of the sidebar; mirrors the classic editor meta-box with score colour badges (green ≥ 80%, yellow ≥ 50%, red < 50%)

Suggestions can be inserted as inline text or as styled link boxes (Minimal, Modern, Paper).

Suggestion Engine

• Manual mode — keyword matching and NLP analysis using your existing content
• Suggestion scope: Entire article, per paragraph, or both
• Category filter — only suggest posts from the same category
• Content age filter — limit suggestions to posts published within a chosen timeframe
• Custom synonyms — define your own word equivalents for smarter matching
• Duplicate anchor detection — prevents inserting the same anchor text twice
• Link prefix text — customise the prefix shown before inserted links (e.g. “Related:”, “See also:”)

Visual Link Skins

Choose how automatically inserted internal links appear on the front end, from Settings › Assistant & Skins:

• Standard link — your theme’s default link style
• Vertical bar accent — a subtle brand-coloured bar beside the link
• Bordered box — an inline pill with a soft border

All built-in skins are text-only and inline-safe, so they never disrupt the flow of your content.

NLP and Indexing

• Porter Stemmer (English) — converts “Running” to “Run” for better matching
• Stopwords filter (English and Indonesian) — ignores common words during indexing
• TF-IDF scoring — identifies the most relevant keywords in each post
• Configurable index sources:
  • Post title (always active)
  • Full post content
  • Meta description (auto-detects Yoast SEO, Rank Math, All in One SEO)
  • TF-IDF calculated keywords
• Background indexing via WordPress Cron

Reports and Analytics

• Overview — at-a-glance metrics for total links, orphan pages, and link health
• Inbound Links — paginated table of all posts receiving internal links
• Outbound Links — all links pointing out from each post
• Anchor Texts — analysis of anchor diversity and reuse across the site
• Opportunities — identifies content that could be better linked
• Click Analytics — 30-day bar chart of internal link click activity
• Google Analysis — real-time data from a connected Google Search Console account
• Audit & Fix — site-wide broken link checker with inline editor highlighting

Visual Architecture Graph

An interactive internal link graph built on the vis-network library. Nodes represent posts; edges represent links. Configure the node limit to keep rendering fast on large sites.

Bulk Operations

• Bulk insert auto-links into selected posts
• Bulk remove all internal links from selected posts
• Bulk re-index all posts (useful after changing NLP settings)
• Re-index button on the Settings › NLP tab for quick access

External Services

This plugin connects to external services only in the following case:

Broken link checker — when you use the Audit & Fix page, the plugin sends HTTP HEAD requests to the URLs found in your content to check whether those external links are still reachable. No content or personal data is transmitted; only the URL itself is contacted. This check is performed on demand and only when you visit the Audit & Fix page.

All NLP processing (stemming, stopwords, TF-IDF scoring, keyword extraction, and link suggestions) runs entirely on your own server — no external service is required or used.

Source Code for Minified Assets

The file admin/js/vis-network.min.js is a minified copy of the vis-network visualization library.

• Source: https://github.com/visjs/vis-network
• License: MIT (Dual licensed MIT and Apache 2.0)

The library is used exclusively to render the interactive internal link architecture graph in NexLink.

Privacy

NexLink is privacy-first:

• All NLP and content analysis runs locally — no content is sent to external servers
• Click analytics store only the link URL and a timestamp — no personal identifiers or IP addresses are recorded
• Connecting Google Search Console is optional and entirely user-initiated
• NexLink registers suggested privacy policy wording with the WordPress Privacy Policy guide
• Personal data export and erasure are supported through the standard WordPress privacy tools
