Backlink Overview API — the whole link profile in one call
Referring domains, total backlinks, follow ratio and Authority Score for any domain. Flat priced no matter how big the profile is, with spam signals computed for you.
What Backlink Overview gives you
Authority Score
A 0-100 measure of overall link strength, directly comparable between any two domains you check.
- 0-100 Authority Score
- Comparable across domains
- Single headline number
- Pairs with Domain Authority
Referring domains, not just links
Raw backlink counts are easy to inflate. Referring domains and referring IPs are the numbers that actually indicate reach.
- Referring domains
- Referring URLs
- Referring IPs
- Total backlinks
Follow ratio computed
The follow versus nofollow split, returned both as raw counts and as a ready-to-threshold ratio.
- Follow and nofollow counts
- Precomputed follow ratio
- Sponsored link count
- UGC link count
Spam signals surfaced
We derive a profile quality rating from the follow ratio and links-per-domain concentration, so you do not have to encode that logic yourself.
- profile_quality rating
- Links per referring domain
- Mostly-nofollow flag
- Ready for scoring rules
Link types broken out
Text, image, form and frame links counted separately — the mix tells you whether links were earned editorially or generated.
- Text links
- Image links
- Form and frame links
- Editorial mix signal
Flat price, any size
This endpoint returns aggregates rather than a row per link, so the price is fixed whether a domain has a hundred backlinks or a billion.
- Flat 13 credits
- No per-row billing
- Bulk CSV supported
- Predictable at scale
One endpoint. A domain in, structured data out.
Same authentication, same credit balance, and the same response envelope as every other 1Lookup product. If you have already integrated one endpoint, this one is a URL change.

Who uses Backlink Overview
Link builders vetting prospects
Score a list of potential link targets before outreach. Drop anything with a low follow ratio or an obviously manipulated profile, so you spend outreach effort only where a link would carry value.
SEO agencies auditing a new client
On day one, quantify whether the client's rankings rest on a healthy link profile or a fragile one — and whether a previous agency built links you now need to disavow.
Competitive analysts
Compare referring domains and Authority Score across an entire competitor set in one bulk job, and size the link gap you would need to close.
Risk and diligence teams
Before acquiring a site, check whether its authority is genuine. A profile dominated by nofollow links from a handful of domains is a very different asset from one with broad editorial coverage.
Frequently asked questions
What does the Backlink Overview API return?
A summary of a domain's entire link profile in one call: total backlinks, referring domains, referring URLs and IPs, the follow versus nofollow split, sponsored and UGC link counts, link types, and an Authority Score.
Does it return the individual backlinks?
No, and that is deliberate. Endpoints that list every individual link bill per row returned, which makes cost unpredictable and can turn a single call into a very large bill. This endpoint is flat priced because it returns aggregate counts, not a row per link.
How do I spot a spammy link profile?
Two signals do most of the work, and we compute both for you. A follow ratio below 30% means most links pass no value. A very high links-per-referring-domain ratio means a small number of sites are firing thousands of links, which is a classic footprint of manipulation. The response includes a profile_quality field summarising both.
How much does it cost?
13 credits per domain, roughly $0.046 on the Growth plan. Flat rate regardless of how large the link profile is — checking a domain with a billion backlinks costs the same as one with a hundred.
Can I run this across a list of domains?
Yes. Backlink Overview is available in the bulk CSV pipeline with exactly linear pricing, which makes it practical for vetting large lists of link prospects or scoring an entire competitor set.
How does this differ from Domain Authority?
Domain Authority measures search performance — keywords, traffic and traffic value. Backlink Overview measures the link graph that underpins it. Run both against the same domain and you can tell whether a site's rankings are supported by real authority or are unusually fragile.
