DA 38 is entry-level editorial territory, and the right place to test whether guest content earns you anything before you spend premium money.
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 38-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 within a few percent of the median on cost and in line with the index median on audience. Listings in that section range from $30 at the cheap end, so the question is not whether $70 is high for a link, but whether it is high for this one.
Where lapzoocom.com is not a topical match for your market, buy it for that plausibility and for whatever brand exposure comes free, and put your exact-match anchors on the sites that genuinely cover your subject. That one discipline is the difference between a general guest post strengthening a profile and the same link making it look synthetic.
Our observation on this host is do-follow outbound links in editorial content. That is the attribute, not the value: the 38 DA and 7k monthly visits are what the attribute is attached to.
