Best backlink APIs: evidence-led shortlist
Backlink indexes and proprietary metrics are not interchangeable. We report what was observed and do not force metric equivalence.
SE Ranking API
VERIFIED HANDS-ON. Backlink research completed for all four frozen domains in the prior Sep 21 run. This proves execution in that environment, not parity with another provider's index.
Mangools / LinkMiner
VERIFIED PRODUCT OBSERVATION. LinkMiner completed all four frozen-domain checks. Current Mangools API documentation exists, but SDB authenticated API access and comparable API cost remain unresolved.
DataForSEO
Our current DataForSEO source pack verifies SERP, keyword-data and AI Optimization families. We have not preserved sufficient SDB hands-on backlink evidence to make a comparative backlink claim on this page.
