Features — Automatic Linker

01 — Editor

Suggestions where you write.

A Gutenberg sidebar (and a TinyMCE button for Classic Editor) shows ranked link suggestions for the post you're editing. Click one, and the anchor inserts directly into the selected block via @wordpress/rich-text.

Top-3 keyword preview per suggestion (stemmed)
Relevance score visible — orphan boost & already-linked penalty applied
Hooks /wp-json/automatic-linker/v1/suggestions behind the scenes

02 — Indexing

TF-IDF on the same box that runs your site.

A two-pass JSONL tokenizer streams your corpus through a memory-bounded indexer. Action Scheduler runs the rebuild in the background — never inline on save_post. WP-Cron fallback if Action Scheduler isn't available.

# 1. First pass — collect document frequencies
foreach ($posts as $post) {
    stream_tf($post, $jsonl);
}

# 2. Second pass — compute TF-IDF vectors
foreach (jsonl_iter($jsonl) as $tf) {
    $vec = tfidf($tf, $idf);
    store($post_id, $vec, norm($vec));
}

# 3. Cosine similarity at query time
cos($a, $b) = dot($a, $b) / ($norm_a * $norm_b);

03 — Auto-linking rules

Keyword → URL replacements that respect your markup.

Define rules for high-value keywords and Automatic Linker rewrites the_content at priority 99 — after blocks render. The engine protects <a>, <code>, <pre>, headings, and shortcodes via placeholder swaps so it never breaks valid HTML.

Per-post and per-site replacement caps
Case-sensitive matching, target="_blank", rel="nofollow"
Filter override: automatic_linker_rule_replacement

04 — Reports

See where your link equity is leaking.

Three reports — orphan pages, inbound counts, and broken links — give you the data you'd otherwise pull together by hand from a crawler. Each is a single SQL query against the cached link graph.

05 — Bulk URL changer

Migrate a URL across your whole site, then roll it back if you need to.

Preview shows you every post that would change before you commit. Apply writes a batch ID to wp_automatic_linker_url_changes, and rollback restores the originals byte-for-byte.

Diff preview before any write

manage_options capability + nonce required

06 — Optional BYOK LLM

Re-rank with your own key, or don't.

If you want sharper relevance for editorial content, drop in your OpenAI or Anthropic key. Automatic Linker hands the top-N TF-IDF candidates to the model for re-ranking. Your key is encrypted at rest with libsodium, never returned by REST, and never written to logs.
