4.9k monthly visits is thin, so the buy here is the citation and the crawl path rather than an audience.
The commercial temptation is exactly what the guidelines punish: promising outcomes. Write about process, access, cost and design, keep treatment claims inside the evidence, and never put a promise in the anchor. That constraint is also why health placements hold value better than most categories, the surviving pages are the careful ones.
Within the Health section of the index — 37 listings, 54 median DA, 4.9k median traffic, $40 median price — this placement is 12% above 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 $45 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 40 DA and 4.9k monthly visits are what the attribute is attached to.
