Internal link graph

Which of your pages link to which others — the structure that decides what a reader and a crawler can reach from the page they are actually on, as opposed to what you have published.

01/What it means

A sitemap is a list of addresses. A link is a reason to go to one. The two are routinely confused, and the confusion is expensive in a specific way: a page listed in the sitemap and linked from nowhere is live, indexed and unreachable to a person, which for a reader is the same as not existing. The name for that state is an orphan page, and almost every site of any size has some without knowing.

Crawlers treat the graph as the argument about importance. A page the site links to from four contexts is being asserted as load-bearing; a page reachable only through the sitemap is being asserted as an afterthought, whatever the sitemap says. Neither claim requires anyone to write it down — the graph is the claim.

The failure is structural rather than editorial, which is why it survives good writing. Nobody sets out to orphan a page; it happens when a section is built, published, and then the thing that would have linked to it is built differently. Discovering it needs a traversal rather than a proofread, and it is the only defect on this list that is both invisible from inside every individual page and trivially machine-detectable.

02/What people get wrong

A site can add three hundred internal links, put them all in the footer, and change nothing: a link every page carries distinguishes no page from any other. What carries information is a link from inside an argument to the thing the argument depends on — which means the useful audit question is never how many links a page has, but which pages have no route into them from any context a reader is plausibly in, and what the site would have to say to justify one.

Where we measured it

A definition proves nothing. These are the places on this site where this quantity was actually computed, with the period and whose figure it is stated beside each one.

A link audit found sixty-seven pages with no internal route into them at all — live, indexed and reachable only from the sitemap. Building the graph took the count to zero.

A definition is free. Being answerable for the figure it produces is the part that is bought, and this term is a working part of the engagements below.

The definitions are the easy part. Whether the figure on your dashboard was computed this way is a different question, and usually the more expensive one.
