TrafficIsNotAuthority

Two sites in the same vertical, both at around 40,000 monthly organic sessions. A placement on one moved a client's target page four positions inside a quarter. A placement on the other did nothing measurable in a year.

The traffic figure was the same. It was measuring demand for the topic, which both had. It was not measuring whether anyone had decided the site was worth trusting on it.

The site that worked earned its sessions across roughly 900 URLs, with the top ten pages accounting for under a fifth of the total. The site that did not earn 71% of its traffic from six pages, all of them calculators, all of them ranking on a template that had been copied a hundred times.

One site had an audience. The other had six lucky URLs and a hosting bill.

• Traffic concentration. Top ten pages under 25% of sessions is a healthy spread. Over 60% and the site is a handful of URLs wearing a publication as a costume.
• Referring domains to deep pages. Links to the homepage are marketing. Links to individual articles are citations, and citations are the thing that transfers.
• Branded search volume. People typing the site's name is the most honest authority signal available and almost nobody checks it.
• Direct traffic share. Anyone returning without a query has decided the site is worth returning to.

Because it is one number, it is easy to verify, and it is the one that goes up when you build the second kind of site. Every signal above takes years to accumulate and cannot be bought in a quarter, which is precisely why they are the ones worth checking.
