DA 38 is entry-level editorial territory, and the right place to test whether guest content earns you anything before you spend premium money.
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 2k monthly visits cannot survive publishing filler, so write for their reader first and your anchor second.
produkey.net has 47 DR against an index median of 51, 2k monthly visits against a median of 5.5k, and a placement price of $35 against $70. Where those three numbers point in different directions, the traffic figure is usually the honest one: it is what a publisher has to protect, and it is what decays first when a site starts selling too much inventory.
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.
Our observation on this host is do-follow outbound links in editorial content. That is the attribute, not the value: the 38 DA and 2k monthly visits are what the attribute is attached to.
