A 37 DA listing at $80 is the price of an experiment: if the article earns citations, you have found a channel; if not, you have lost one invoice.
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 37-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.
Ranked against the 2,000 listings we index, singletopicnews.com sits in the top 81% for audience and the top 29% for authority, at $3.25 per thousand monthly visits. Inside the DA 30-39 band (892 listings) that price ranks 155th for value, which is the comparison to use: nobody competes with the whole index, they compete with the sites a buyer would book instead.
General-interest publications are the workhorses of a link profile and the easiest place to overpay. The article shape that works is boringly specific: a problem, the method used, what happened, what it cost. A general title with 24.6k monthly visits survives because it answers questions well, not because it loves contributors, so a piece with nothing verifiable in it gets edited down to a bio link.
Our observation on this host is do-follow outbound links in editorial content. That is the attribute, not the value: the 37 DA and 24.6k monthly visits are what the attribute is attached to.
