If you source links from both adxom.com 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 4,390 domains — 77% of adxom.com and 8% of links.me. As a Jaccard index (shared ÷ combined) the catalogs are 8% identical, so about 92% of the combined pool is exclusive to one side.
Unique inventory
- 1,277 domains on adxom.com only (23% of its catalog).
- 51,379 domains on links.me only (92% 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.
