Separate the arrangement from the sales label
"Editorial," "niche edit," and "premium placement" do not tell you whether a link was purchased. Ask who receives payment, what is promised, and how the relationship is disclosed.
Google identifies buying or selling links for ranking purposes as link spam. Paid advertising can have a legitimate purpose, but its links should be qualified appropriately.
Questions to ask a seller
Request the proposed page, the reason its audience fits your business, the editorial process, and the link treatment. Be wary of offers that guarantee ranking movement or hide where the link will go until after payment.
A relevant sponsored article may make sense as advertising if you evaluate its audience and cost honestly. It should not be dressed up as independent product endorsement.
Compare the costs you can see
Earning coverage costs time: research, a useful product story, drafting, and conversation. Software or a service may reduce that work. Paying for outreach work is different from paying another site to insert an unqualified ranking link.
For example, hiring someone to identify relevant reviews and ask for an independent evaluation does not guarantee that any review will be published. A contract promising a fixed anchor on an unnamed site is a different arrangement.
Our choice
We would prefer a smaller set of relevant conversations where the writer can say no. That leaves room for an accurate recommendation and avoids pretending a purchased placement is a neutral editorial decision.
Ask how success will be reported. Sent pitches, accepted coverage, sponsored placements, and referral purchases belong in different columns.
