bklink is a web-based backlink intelligence tool that resolves the host, IP, ASN and live follow state behind every link in a paid placement list, prices each placement against what the market actually pays for links of that kind, and re-checks URLs for link rot before an agency's client notices.
What is bklink?
bklink is a backlink audit tool hosted at bklink.uk. It takes a link portfolio as an uploaded CSV, a PDF, a dropped spreadsheet, or a scanned domain, then resolves where each publication actually lives — host, IP, ASN, subnet C-block and live follow state — groups placements by the vendor or PR distribution agency that sold them, and returns a dollar estimate per link plus a total report value. The output is a dated PDF report (a sample press-release distribution agency audit, 173 publications, is published on the site) with a per-link table of rank, live follow state, network class and market value, along with summary figures for shared infrastructure, unique IPs and dead links.
Key Features
- Multi-format intake — upload a CSV or PDF placement list, drop a spreadsheet, or scan a domain directly; one audit covers up to around 400 domains, and larger profiles scale to a $1.92 ceiling.
- Host, IP, ASN and follow-state resolution — in the published sample, 36 unique IPs sat behind 172 resolvable publications.
- Subnet C-block detection — identifies publications sharing the same cheap hosting cluster; the sample found 140 of 172 placements co-hosted, with 81% of the footprint on shared clusters and the largest cluster alone accounting for 9%.
- Agency attribution audit — groups each audited link by the provider or PR distribution agency that sold it, so you can see how many of a vendor's placements were co-hosted spam.
- Link rot detection — the sample flagged 4 dead (404) links, which were priced out of the $1,980 valuation.
- Market-value pricing — assigns a per-link dollar figure; co-hosted links in the sample were discounted roughly 95%.
- Property value projection — the sample report models estimated property value rising from about $4,000 to $31,204 over twelve months as dead and shared-host links are identified and replaced.
- Status re-check — re-verifies every URL and recalculates the report around what is still live, without paying for vendor lookups again.
Who should use bklink?
- SEO agencies reconciling a client's purchased link list against the invoice, before deciding whether a vendor is worth paying again.
- PR and outreach buyers checking whether a press-release distribution agency's placements landed on a handful of shared hosting clusters rather than the diverse sites promised.
- In-house link builders validating a vendor's "diverse placement" claim before signing off on a renewal.
- Freelance SEO consultants producing a dated PDF evidence report for a client whose link budget needs a defensible return figure.
What can you do with bklink?
- Audit a 173-link PR campaign: get a per-placement table of live follow state, network class and market value, revealing 140 co-hosted placements and a $1,980 corrected estimate.
- Check a vendor's delivery: group every sold link by the agency that supplied it and see how many of their placements share infrastructure.
- Catch link rot after purchase: re-run a status check to find URLs that have gone dead and re-price the report around what is still live.
- Defend a budget: download the PDF report and show a client the gap between an invoice and the audited market value of what was delivered.
How does bklink work?
- Add funds to a wallet (minimum top-up $10, roughly nine audits), or start with the $1 credit given at signup.
- Supply the portfolio: upload a CSV or PDF, drop in a spreadsheet, or scan a domain.
- bklink resolves hosts, IPs, ASNs, subnet C-blocks and follow state, groups links by selling vendor, and prices each placement.
- Download the PDF report, or re-run a status check for $1 and let the dollar value recalculate around the links still live.
Pricing
bklink uses a prepaid wallet with per-action pricing rather than a subscription: a backlink audit costs $1 (up to around 400 domains, with a $1.92 ceiling for larger profiles), a status re-check costs $1, and the minimum top-up is $10 — around nine audits. Nothing renews and nothing is billed monthly. New accounts receive $1.00 of credit, enough for one full audit with no card required, and unspent balance is refundable under the refund policy.
Alternatives
Ahrefs and Semrush, both subscription SEO suites that bundle backlink indexes with other tooling rather than selling a per-audit placement valuation.
FAQ
Is bklink free?
New accounts get $1.00 of credit — one full backlink audit, with no card required. After that you top up a wallet, minimum $10, and each action (audit or status re-check) deducts its price when it runs.
Does bklink require a subscription?
No. bklink is prepaid, never recurring. You add funds to a wallet, each action deducts its own price, and any unspent balance is refundable under the posted refund policy.
What does a bklink report actually contain?
A per-publication table with rank, live follow state, network class (for example AS16276 Cluster A) and market value, plus headline figures for publications inspected, dofollow ratio, median rank, shared infrastructure percentage and estimated total value, exportable as PDF.
What inputs does bklink accept?
Three routes: upload a CSV or PDF placement list, drop in a spreadsheet, or scan a domain. A single audit covers up to around 400 domains.
Can bklink tell me if a link has gone dead?
Yes. Re-checking every URL costs $1 and recalculates the report value around the links still live. The published sample audit found 4 dead 404 links out of 173 placements and priced them out of the estimate.
