Find every missing internal link.
BERTlinker reads every page on your site, groups them by meaning, and shows you the internal links a keyword-overlap tool would never find.
Works with any crawler
Keyword tools miss meaning. BERTlinker doesn't.
Keyword-overlap tools only match pages that share the same words. BERTlinker reads page content with sentence-level embeddings, so it catches the connections a manual audit would miss.
Category → Buying guide
“Hair Care” category links to “Hair Straighteners Buying Guide”. Zero shared keywords, strong semantic match.
Help article → Category
“How to Choose a Pushchair” links to the Pushchairs category. Help pages become part of the linking structure.
Category → Category
“Running Shoes” links to “Running Socks & Accessories”. Cross-category links that boost competitive head terms.
How it works
Three steps to better internal links
Upload your crawl
Drag & drop a CSV or Excel export from Screaming Frog, Sitebulb, Ahrefs, or any other crawler.
BERT finds connections
Sentence Transformers encode every page into a vector and compute pairwise similarity. No keyword overlap needed.
Export & implement
Browse results in the interactive dashboard, filter by folder, check which links already exist, and download a formatted Excel report.
Try the live demo
Real recommendations from a sample crawl. Browse every suggestion grouped into AI-labelled topic clusters, filter by folder, score range and quality tier, then switch to the Folders view to see how your site sections link to each other. The same run also checks which links already exist on the live site.

See how your sections link to each other
The Folders tab lists every cross-folder relationship on your site, like /guides linking to /products, with the number of suggested links and the average similarity for each pair. Sort by either column to find the section pairings worth connecting first.
Once you have unlocked a run you can download the suggestions for any single folder pair as its own Excel or CSV file, so a writer can work through one section at a time without wading through the whole site.
The table appears automatically whenever a site has more than one folder, so single-section sites are never shown an empty view.
| Source → Target | Links | Avg. similarity |
|---|---|---|
| /guides → /products | 48 | 0.81 |
| /blog → /guides | 31 | 0.74 |
| /products → /collections | 22 | 0.69 |
What you get
Every run includes AI-labelled topic clusters, cross-folder linking relationships, already-linked detection, smart blocking rules, and a colour-coded Excel report. Not just a list of links.
Topic Clustering
Every page is grouped into named topic clusters automatically, so you review recommendations topic by topic instead of scrolling one long list.
Actionable Excel Export
A branded workbook with every suggestion, a red-to-green similarity heatmap, a Folder Relationships sheet, and a native PivotTable that refreshes on open. Run the link check and you also get split Link Opportunities and Already Linked sheets.
Download sample ↓Smart Rules
Block folder-to-folder link patterns you never want suggested, for example blog → blog self-linking. Blocks apply across the dashboard and every export, and the tool can suggest blocks for you.
Folder relationships
The Folders tab shows every cross-folder linking opportunity, for example /guides to /products, in a sortable table with link counts and average similarity for each pair.
Already-linked detection
A background check crawls your live source pages and flags which suggested links you already have, reading the existing anchor text. You see only the genuine gaps to add, not links that are already in place.
Free to browse, pay once
Upload any size site and browse every recommendation without an account or a card. When you want the full export, it is a single one-time fee from $9, priced by result count. No subscription.
- • Summary cover sheet with Strong, Moderate and Weak counts and your top clusters and folder pairs
- • Results sheet, one row per suggestion, with a colour scale on the similarity column and auto-filter
- • Link Opportunities and Already Linked sheets when a link check has run
- • Folder Relationships sheet matching the Folders tab
- • A native PivotTable that refreshes when you open the file
An Excel report you can hand straight to a developer
Every recommendation exports to a single workbook with the similarity score colour-coded from red to green, a match strength label on each row, and source and target page titles and meta descriptions alongside the URLs. Freeze panes and an auto-filter are already set, so it is ready to sort, filter and action without any cleanup.
If you have run a link check, the workbook splits the suggestions into a Link Opportunities sheet for links that are still missing and an Already Linked sheet for ones that exist, so you only work on what is left to do. You can also export a single topic hub or a single folder pair as its own file.
Free runs export the top 500 rows with the full site-level summary intact. Unlocking a run, a one-time fee from $9, exports every row.
