A 39 DA listing at $35 is the price of an experiment: if the article earns citations, you have found a channel; if not, you have lost one invoice.
Where a site in this group carries 5.6k visits a month, expect the editorial desk to check whether your brand has any existing footprint: review profile, registration with the relevant professional body, a physical address. Those checks protect their own standing, and passing them quietly strengthens yours.
Within the Health section of the index — 37 listings, 54 median DA, 4.9k median traffic, $40 median price — this placement is 12% below the median on cost and in line with the index median on audience. Listings in that section range from $20 at the cheap end, so the question is not whether $35 is high for a link, but whether it is high for this one.
Health is a YMYL category, which means the page that hosts your link is judged on the same standards as the content on it. Editors working in this space ask for named authors, professional affiliation and a citation list because their own pages can be demoted for thin or unsourced advice. A contribution with no qualified byline is the most common rejection we see.
Our observation on this host is do-follow outbound links in editorial content. That is the attribute, not the value: the 39 DA and 5.6k monthly visits are what the attribute is attached to.
