If you source links from both collaborator.pro and links.me, one number decides how much you overwrite yourself: how much do their site databases overlap? We matched both catalogs on the normalized domain (lowercased, no scheme or www) inside our Backlink Pricing dataset.
The overlap
The two databases share 18,624 domains — 62% of collaborator.pro and 33% of links.me. As a Jaccard index (shared ÷ combined) the catalogs are 28% identical, so about 72% of the combined pool is exclusive to one side.
Unique inventory
- 11,268 domains on collaborator.pro only (38% of its catalog).
- 37,145 domains on links.me only (67% of its catalog).

FAQ
Does "on both" mean the same seller?
Not necessarily — a domain can be listed on both marketplaces by the same publisher or different resellers. What's shared is the placement opportunity, which is what you dedupe before buying.
Is a bigger database always better?
No. Overlap, price spread, DR/traffic quality and geography decide value for a specific campaign. Comparing databases is how you buy the same link for less and find inventory a single platform can't offer.
