4M monthly visits means the host has something to lose from publishing junk, which is the practical reason large sites are safer even when they are pricier.
The commercial value here is different from a general blog: a link from a technology title is usually read by people who will mention it somewhere else. That is why an article with a real number in it keeps returning value a year later, while a listicle about trends dies in the archive. Give the editor something they can cite.
Within the Technology section of the index — 53 listings, 41 median DA, 15.5k median traffic, $40 median price — this placement is 188% above the median on cost and about 727.3× the index median on audience. Listings in that section range from $30 at the cheap end, so the question is not whether $115 is high for a link, but whether it is high for this one.
Tech audiences are the least tolerant of marketing dressed as engineering, and the editors of these sites know it. The pieces that get published, indexed and then linked to by other people are the ones with a claim, evidence and a reproducible method. Anything that reads like a feature list gets cut back to two sentences and a bio link.
The index lists this property's editorial links as followed. Availability of a followed link changes with the site's monetisation decisions, so we confirm the tag on the live URL before counting delivery.
