Internal Link Map Visualizer (CSV & Screaming Frog)

Map your site's internal link structure with a force-directed graph. Import data from Screaming Frog "All Inlinks" reports, CSV exports, or manual entry. Spot orphans, rank hubs, and export visualizations — all in your browser.

What you get:

  • Interactive network graph with orphan highlighting
  • Inbound link count sizing (bigger nodes = more authority paths)
  • Export to SVG, PNG, or CSV for reports
  • Privacy-safe: processing stays local, URLs never leave your device

How to use:

  1. Export your internal links from Screaming Frog (Bulk Export > All Inlinks) or build a CSV with Source URL and Destination URL columns
  2. Paste or upload the data
  3. View the graph, toggle orphans, and export

Perfect for SEO audits when you need a visual map of link distribution without uploading site data to third-party servers.

How does the Internal Link Visualizer work step by step?

The internal link map builds a directed graph from link relationships you supply. Two input paths: (1) Manual entry of source pages and outbound targets; (2) CSV paste or one-click Screaming Frog All Inlinks file import (Source and Destination columns), processed entirely in the browser. Node size reflects inbound link count so hubs stand out. Orphan pages (zero inbound links among the mapped set) are highlighted so you can fix internal linking gaps.

Learn how internal link mapping works, including orphans, hubs, click depth, and when to use Screaming Frog exports versus browser tools, in the internal link mapping guide.

What does a typical Internal Link Visualizer result look like?

You have a blog with 5 pages: | Page | Links to | |------|----------| | /homepage | /blog, /pricing | | /blog | /post-1, /post-2 | | /pricing | /homepage | | /post-1 | /post-2 | | /post-2 | (nothing) | Load the demo dataset above the fold to see this pattern as a live graph, including an orphan landing page with no inbound links.

Frequently asked questions

  • What is internal link mapping?

    Internal link mapping is the process of visualizing how pages on your site link to each other. It shows which pages are well-connected (hubs), which pages have no incoming links (orphans), and how link equity flows through your site structure. SEO teams use link maps to find orphaned content, identify over-linked pages that dilute authority, and plan internal link campaigns that push PageRank toward high-value pages.

  • Do I need to give you my website URL?

    No. This tool does not crawl your site. You bring your own data — either from a Screaming Frog export, a CSV you built, or manual entry. That means your internal link data stays on your device and never leaves your browser. If you need a live crawl tool, use Screaming Frog or Sitebulb instead, then bring their output here for visualization.

  • What format should my CSV be?

    Two columns minimum: Source URL and Destination URL. Each row is one internal link. Optional third column: Anchor Text. Example: Source URL,Destination URL https://example.com/page-a,https://example.com/page-b https://example.com/page-b,https://example.com/page-c You can also paste Screaming Frog's "All Inlinks" bulk export directly — this tool reads the standard SF format.

  • How is this different from LinkWhisper or SerpView?

    OnSumo: Visualizes data you already have (SF exports, CSV). Browser-only, no upload, no account. Best for privacy-focused audits or when you already use Screaming Frog. LinkWhisper: WordPress plugin with live-site crawl. Great if you run WP and want in-dashboard linking suggestions. SerpView / LinkMap: Free crawl tools (paste a URL, they crawl it). Faster to start if you don't have export data, but your URLs are sent to their servers. Pick the tool that fits your workflow and privacy requirements.

  • What are orphan pages and why do they matter?

    Orphan pages have zero internal links pointing to them. Google can still find them via your sitemap, but they get no PageRank flow from your site's link graph — which can hurt their ranking potential. This visualizer highlights orphans in the graph so you can decide: delete them, noindex them, or add internal links from relevant hub pages.

  • Can I use this for large sites (1000+ pages)?

    Yes, but browser performance depends on your device. Force-directed graph layout gets slower above ~500 nodes on older machines. For massive sites, filter your export to one section or subdirectory before importing. For full-site crawl maps at enterprise scale, use Screaming Frog's built-in visualizations or Sitebulb's crawl maps instead.

  • What formats can I export?

    SVG — editable vector for design tools. PNG — raster image for reports and slides. CSV — re-import or analyze in spreadsheets. Exports include the current graph state (filtered nodes, layout positions).

See your site as a graph

Internal links decide how authority moves through your site and how easily crawlers find pages. A list of URLs hides that. A map shows it. This tool draws your pages as dots and your links as lines, using a force layout that pulls linked pages together.

You can pan and zoom. Big clusters are your strong areas. Dots drifting at the edge are trouble.

Orphan pages

An orphan page has no internal links pointing to it. Visitors can't click their way there. Crawlers may only find it through the sitemap, if at all, and Google treats it as less important.

The tool highlights orphans so you can fix them. Link from a related page with natural anchor text, or decide the page isn't needed and remove it.

Importing your data

You don't give the tool your URL. You upload a CSV exported from a crawler, with source and target columns. The file is read in your browser and never sent anywhere.

Large sites work, but the map gets dense past a thousand pages. Filter to a section first.

What to look for

Fix the biggest gaps first. One link from a strong page can matter more than ten from weak ones.

  • Money pages with few links in
  • Old posts with many links out and none in
  • Clusters cut off from the rest of the site
  • Pages three or more clicks from the home page

Make it routine

Re-run the map after big content pushes. New posts often arrive with no links to them. Add links as part of publishing, not as a cleanup job months later.
