At entry pricing we book these in sets rather than singly: one cheap link proves nothing, six spread over two months is a pattern.
Seasonality governs everything here. A placement published three months before the peak season for the destination accumulates internal links, refreshes and round-up mentions; the same article published in the off-season gets crawled and left alone. If the site covers budget flying, time the pitch to their planning window rather than to yours.
Within the Travel section of the index — 18 listings, 54 median DA, 3.9k median traffic, $30 median price — this placement is 17% below the median on cost and roughly 66% of the index median on audience. Listings in that section range from $20 at the cheap end, so the question is not whether $25 is high for a link, but whether it is high for this one.
Because these pages are updated, check what an update does to a placement. On aggressive sites the URL persists but content gets rewritten, and your paragraph is the first thing to go. Ask for a written note of the commitment before publishing and take a dated screenshot; ours is in the report.
Our observation on this host is do-follow outbound links in editorial content. That is the attribute, not the value: the 55 DA and 3.6k monthly visits are what the attribute is attached to.
