Relevance and editorial quality come first
For link building for ecommerce, a few relevant placements usually do more than many loosely related ones. We favour publishers whose readers could realistically buy from you. The link sits in the body of an original article, and the anchor text reads naturally. We judge quality by relevance, editorial standards, real readership and placement context, not by a single authority score. Publishers control link attributes. Some mark paid or contributed content with rel="sponsored" or rel="nofollow", in line with Google's guidance, and your report shows which applies to each placement.
