A solid line is a reading. A break is a day nobody looked. A dashed run is the last reading carried forward, which is a drawing decision rather than a measurement.

A 0 to 100 score of how strong a domain’s backlink profile is, on a logarithmic scale, so the distance from 70 to 80 is far larger than from 10 to 20.

The axis is flipped, so a rise on this chart is a rise in the list.

Position in the Tranco list, a research ranking of the million most popular domains averaged over thirty days so a single day’s traffic spike cannot move it.

Read from iij.ad.jp/robots.txt. “Not named” means the file says nothing about that agent, which is not the same as allowing it: a catch-all rule added later blocks it without anyone deciding to.
