115k a month is solid mid-size traffic: enough that the host maintains its pages, small enough that a well-written contribution stands out in the queue.
Where eirdwealth.net is not a topical match for your market, buy it for that plausibility and for whatever brand exposure comes free, and put your exact-match anchors on the sites that genuinely cover your subject. That one discipline is the difference between a general guest post strengthening a profile and the same link making it look synthetic.
Within the General section of the index — 1,576 listings, 39 median DA, 5k median traffic, $70 median price — this placement is 29% above the median on cost and about 20.9× the index median on audience. Listings in that section range from $30 at the cheap end, so the question is not whether $90 is high for a link, but whether it is high for this one.
Generalist inventory also varies more than any other kind, which is why the numbers in this brief matter more than the label. A 37 DA domain with 115k estimated monthly visits and Do-follow links is a different product from the same DA with a tenth of the traffic, and they are priced too close together in most catalogues.
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.
