Sponsored link question

Noticed a few websites that offer sponsored posts, but don't actually mark the link as "sponsored", "no follow" or "usg" presumably due to a lack of technical knowledge.

Typically they just have a note at the bottom saying "Sponsered by X" but that's all.

Would you still purchase these with your budget? I have noticed some big publications do this and I have gained links from them.

They appear in ahrefs and appear to be totally legit.

Eager to hear your thoughts.

guest post sellers DO know what those tags are, and the fact that they purposely leave them out it means that they want to offer value to their buyers, which is good IMO.

So yes, I would buy links from them (if their sites are not link farms and / or low quality, of course)

Sponsored links are good to buy when it comes to guest posts.
You need to check whether the price is worth, Metrics genuinely built and not link farms as well.
