At $45 this is a budget listing; the maths still has to work, and it works when the page is topical and the host is active.
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.
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 roughly 35% of 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.
Where a site in this group carries 2k 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.
Our observation on this host is do-follow outbound links in editorial content. That is the attribute, not the value: the 56 DA and 2k monthly visits are what the attribute is attached to.
