FAQ

How does the suggestion algorithm work?

LinkBoostr uses TF-IDF (Term Frequency-Inverse Document Frequency) to analyze your content. It extracts keywords, calculates their importance across your site, and uses cosine similarity to find related posts. This is a proven NLP technique used in search engines and recommendation systems.

Will this slow down my site?

No. Indexing happens in the background using WordPress cron. Suggestions are cached for 1 hour, and database queries are optimized. On average, suggestion requests take less than 500ms.

Can I use this with Gutenberg?

Yes! LinkBoostr has a beautiful sidebar panel for Gutenberg that shows suggestions as you write. Just click the “Link Suggestions” icon in the sidebar.

Does it work with Classic Editor?

Yes. LinkBoostr includes a meta box for Classic Editor with the same suggestion features. Just click any suggested anchor text to insert the link.

Can I exclude certain post types?

Yes. Go to Settings > DILA Settings and check the boxes for post types you want to exclude from indexing.

Is it multisite compatible?

Yes. LinkBoostr works on WordPress multisite with per-site indexing and settings.

How do I find orphan pages?

Go to Tools > LinkBoostr Orphans in your WordPress admin. You’ll see a list of all posts with zero internal links, along with suggestions for which posts should link to them.

Does it work with page builders?

LinkBoostr works with Gutenberg and Classic Editor out of the box. Basic compatibility with Elementor and other builders is included, but full integration is planned for the Pro version.

Can I manually trigger reindexing?

Yes. Go to Settings > LinkBoostr Settings and click “Reindex All Posts”. This will clear the existing index and rebuild it in the background.

Is my data secure?

Yes. All API endpoints require proper authentication (WordPress nonces and capability checks). Your content never leaves your server—all processing happens locally.
