With 8.7k estimated visits, be honest about what you are paying for: $40 buys you a permanent link on a maintained page, not exposure.
There is a second job these placements do that is worth naming: they make a young or thin profile look normal. A domain that acquires 43-level links from a spread of ordinary publications, in drips, over months, looks like a business that has been around. A domain that acquires forty links from aggressive networks in a fortnight looks like a campaign, and it is the pattern rather than the individual link that gets noticed.
Within the General section of the index — 1,576 listings, 39 median DA, 5k median traffic, $70 median price — this placement is 43% below the median on cost and about 1.6× 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.
Generalist inventory also varies more than any other kind, which is why the numbers in this brief matter more than the label. A 43 DA domain with 8.7k 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.
Our observation on this host is do-follow outbound links in editorial content. That is the attribute, not the value: the 43 DA and 8.7k monthly visits are what the attribute is attached to.
