straight to the point - and fair enough.
I've seen a lot of these "looking for guest posts" threads, and the paid/free split usually tells you everything about the quality of the sites involved. If it's paid, you're often looking at PBNs or low-effort content mills that'll pass zero link equity after the next core update. if it's free, you're trading time for placement on something that might actually have some editorial standards.
either way, worth asking: what's the niche, what's the site's current DR, and are they actually indexing the links? I've had more success building relationships with editors directly than replying to these posts, but if the price is right and the metrics hold up, paid can work for certain programmatic plays.
just don't expect long-term value from a bulk guest post deal - those tend to get deindexed within six months.
