How it works
Drop your crawl export
CSV from any crawler, XML sitemaps too. Columns are auto-detected so there's no manual mapping.
BERT finds hidden relationships
Every page is compared semantically using sentence-transformer embeddings. Related pages surface even when they share no keywords. 500 pages in ~4s. 50k in under 5 min.
Export and implement
Interactive dashboard with filters by folder, score, and search. Download a formatted Excel workbook for your team.
What SEOs use it for
BERTlinker uses sentence-transformer embeddings to surface semantic relationships between pages. It finds connections that keyword matching and anchor text analysis miss.
Interlink related products within category text
Surface product pages that are semantically related to category descriptions, even when they share no keywords.
Show related categories on existing category pages
Find category-to-category connections that break content silos and improve crawl paths.
Surface content that assists conversion
Link buyers' guides, how-to articles, and blog posts to the product and category pages where they'll drive the most revenue.
