Current Scores

Web-graph authority (0-100)

Domain scores measure chaindoc.io as a whole: every subdomain's links rolled up into one node of Common Crawl's domain-level web graph. Host scores measure the exact hostname chaindoc.io. WWW scores cover the www variant of that hostname, which the graph tracks as its own entry since January 2026 (before that, www and bare host were merged). A big gap between domain and host usually means the domain's authority lives on other subdomains. PageRank is link-endorsement authority: how much weight the sites linking here carry themselves. Harmonic centrality measures reach: how close this site sits to the rest of the web when following links, which favors broadly connected sites over ones boosted by a few heavy linkers. All are normalized 0 to 100 within each crawl snapshot; a dash means that series does not exist for this site.

{"@context":"https://schema.org","@type":"FAQPage","mainEntity":[{"@type":"Question","name":"What is Chaindoc and who is it for?","acceptedAnswer":{"@type":"Answer","text":"Chaindoc is an agreement management platform. You sign contracts, verify identity with built-in KYC, and collect payments — without bouncing between three tools.\n\nIt fits SMBs and mid-market teams that handle real contracts: real estate, healthcare, insurance, fintech, IT services. The whole loop — draft, sign, verify, pay — runs from one workspace."}},{"@type":"Question","name":"How does Chaindoc compare to DocuSign, PandaDoc, or Adobe Sign?","acceptedAnswer":{"@type":"Answer","text":"Chaindoc bundles e-signature, KYC, and payments in one workflow. DocuSign, PandaDoc, and Adobe Sign require separate tools for identity verification and payment collection.\n\nSide-by-side: DocuSign, PandaDoc, Adobe Sign, HelloSign."}},{"@type":"Question","name":"What does it cost to switch from my current e-signature tool?","acceptedAnswer":{"@type":"Answer","text":"Zero migration fee. Import your templates as PDFs, set up signing flows in the dashboard, invite your team. Most teams switch in under an hour.\n\nSee pricing for what you'd pay on Chaindoc — typically a fraction of per-seat plans on DocuSign or Adobe."}},{"@type":"Question","name":"How does Chaindoc handle document signing and agreements?","acceptedAnswer":{"@type":"Answer","text":"Upload a PDF or pick a template. Drop in signature fields. Add signers, set roles, send. Every step is logged — who signed, when, from where, with what verified identity.\n\nThe signed document lands back in your dashboard with a SHA-256 hash on the blockchain. Anyone can verify it — including the courts."}},{"@type":"Question","name":"Does Chaindoc support KYC and identity verification?","acceptedAnswer":{"@type":"Answer","text":"Yes. KYC is built into the signing flow — signer uploads ID, we verify, then they sign. No separate KYC vendor, no tab-switching.\n\nYou can require identity verification before anyone signs. Useful for financial agreements, real estate deals, anything where you need to know who's actually on the other end.\n\nThe verification result is attached to the signed document. When someone asks \"did you check their identity?\" — you have a record, not a memory."}},{"@type":"Question","name":"How do payments work in Chaindoc?","acceptedAnswer":{"@type":"Answer","text":"Contract gets signed, payment triggers. No separate invoice, no \"please pay within 30 days\" email.\n\nEach payment ties to a specific agreement — amount, terms, due date visible to both sides. Works for one-time deals, recurring arrangements, and milestone payouts. Powered by Stripe.\n\nPayment status lives next to the contract — see what's signed and what's paid without checking two systems."}},{"@type":"Question","name":"How does Chaindoc ensure security and trust?","acceptedAnswer":{"@type":"Answer","text":"End-to-end encryption on every document. Blockchain audit trail on every signature — cryptographically sealed and timestamped. Edits, views, signature events all logged immutably.\n\neIDAS-, ESIGN Act-, and UETA-compliant. ISO 27001 and CSA STAR certified. The security stack is audited by third parties — not just described in marketing copy."}},{"@type":"Question","name":"Is Chaindoc eIDAS and ESIGN Act compliant?","acceptedAnswer":{"@type":"Answer","text":"Yes. E-signatures in Chaindoc are PAdES-BES Advanced Electronic Signatures (AES) under eIDAS Article 26, valid under ESIGN Act (US) and UETA. Contracts signed here are enforceable in the EU, US, UK, and most jurisdictions that accept electronic signatures.\n\nCertifications: ISO 27001, ISO 9001, CSA STAR. Each signature gets a blockchain audit trail — the kind of record that holds up when someone asks for proof."}},{"@type":"Question","name":"What kind of audit trail does Chaindoc provide?","acceptedAnswer":{"@type":"Answer","text":"Each signed document gets a record: who signed, when, their verified identity, the SHA-256 document hash, and the blockchain transaction ID.\n\nAnyone can check whether the document was altered since signing — compare the hash, done. The record sits on a blockchain, so it can't be edited after the fact. Not by the other party, not by Chaindoc, not by anyone.\n\nHealthcare, finance, insurance, real estate teams use this when they need to prove exactly what was signed and that nothing changed afterward."}},{"@type":"Question","name":"Can Chaindoc be used for technical and product documentation?","acceptedAnswer":{"@type":"Answer","text":"Yes. Chaindoc supports technical docs, product specs, internal knowledge bases, and API documentation alongside contracts.\n\nUpdates are tracked — teams can always see how content has changed. This fits teams that treat documentation as a long-term asset, where reliability and history matter."}},{"@type":"Question","name":"Can Chaindoc integrate with existing tools and systems?","acceptedAnswer":{"@type":"Answer","text":"Yes. Chaindoc connects to your stack via REST APIs and webhooks. CRMs, billing platforms, in-house tools — drop Chaindoc into your existing workflow.\n\nAutomate document generation, signing flows, agreement tracking. Same security and audit guarantees, embedded in your systems."}}],"url":"https://chaindoc.io","inLanguage":"en-US"}

Web-Graph History

Authority over time

Every Common Crawl web-graph release since 2017, roughly quarterly. The domain series goes back to 2017; Common Crawl only began publishing the host-level graph in 2020, so host lines start there. Click a legend entry to show or hide that line. Flat lines are normal for established sites; watch for sustained rises or drops, which track real gains or losses in who links here.

A note on www: through the end of 2025 the source web graph merged www and non-www hostnames into the bare name, so one host line covers both. Starting in January 2026 the graph splits them into separate entries, which is why www can carry its own scores going forward.

Backlink Data

Backlink counts

Unique linking domains seen in Common Crawl's link graphs. This is a different dataset than the 0-100 authority scores above: these are raw counts, host-level for chaindoc.io and domain-level for chaindoc.io with all its subdomains combined. Common Crawl covers a large sample of the web, not all of it, so treat counts as comparable between sites rather than absolute totals.
