Internal Link Distribution Calculator

Assess how internal links are distributed across a site and find orphaned depth.

About Internal Link Distribution Calculator

Pages with no internal inbound links are rarely crawled or ranked regardless of their content. Click depth beyond about five reduces crawl frequency sharply. Internal linking is entirely within your control, which makes it the cheapest authority redistribution available.

Formula

Internal Link Distribution

Average links per page = total internal links ÷ pages; orphan share = orphans ÷ pages

orphan page: A page with no internal inbound links, effectively invisible to crawlers
click depth: Minimum clicks from the homepage to reach a page

Worked example

With the default values below, Internal Link Distribution Calculator returns Average Internal Links per Page of 8.000. Change any input above and every figure here is recalculated in your browser.

Inputs used

Total pagesminimum 1: 1,200
Total internal linksminimum 0: 9,600
Pages with no internal inbound linksminimum 0: 85

Results

Average Internal Links per Page: 8.000
Share of Pages Orphaned: 7.083%
Pages With Internal Inbound Links: 1,115
Click Depth Rating: Deep — pages beyond depth five are crawled less often
Recommendation: Link the orphaned pages from relevant hub pages

Assumptions and limits

The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
