Most "related posts" plugins match on category or tag, which means a niche post about widget-testing recommends every other tagged-widget post regardless of actual relevance. KoalaLinks uses semantic vector search instead: it actually understands what each post is about and surfaces real semantic neighbors.
How it works
- Index your site: point KoalaLinks at your sitemap. URLs are crawled and embedded into Pinecone.
- Add the snippet: single line of JS in your site's
<head>. - Render the widget: call the widget mount point in your template; the widget serves the top 8 most-similar URLs, computed with Pinecone when your site is indexed.
- Auto-excludes the current page from its own recommendations.
Why semantic beats category-based
A category-based widget on a blog post about "Best AI SEO Tools for Agencies" might recommend every post tagged "SEO", including beginner-level "What is SEO?" posts that aren't really related. A semantic widget understands the post is specifically about AI SEO tools for agencies and recommends posts that match that specific intent.
The result: higher CTR on related-posts widgets, longer time on site, more pages per session.
Output format
The widget returns URLs + similarity scores. You control the rendering (title, thumbnail, snippet) based on data you already have for each URL (from your CMS, frontmatter, or metadata).
Pairs with internal linking
The same Pinecone index powers KoalaLinks' internal linking feature. Related posts is the sidebar version; internal linking is the inline version. Both reuse the same semantic understanding of your site.
Settings
Toggle the related-posts widget on/off per domain in your KoalaLinks settings. It defaults to enabled.
Performance
Widget queries hit Cloudflare KV (which caches Pinecone results). Typical response is single-digit milliseconds. The widget renders client-side without blocking your page render.
