At $40 this is a budget listing; the maths still has to work, and it works when the page is topical and the host is active.
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 within a few percent of the median on cost and about 1.9× the index median on audience. Listings in that section range from $30 at the cheap end, so the question is not whether $40 is high for a link, but whether it is high for this one.
Expect editorial standards to be enforced on the structure as well as the tone: no thin affiliate comparisons, no recycled press copy, links that go somewhere the reader needs rather than somewhere you want. Sites with 10.2k monthly visits cannot survive publishing filler, so write for their reader first and your anchor second.
Our observation on this host is do-follow outbound links in editorial content. That is the attribute, not the value: the 39 DA and 10.2k monthly visits are what the attribute is attached to.
