Site Information
nitrosign.com
Link authority for nitrosign.com (registrable domain: nitrosign.com) from the Common Crawl web graph: PageRank and harmonic centrality history since 2017, current scores, and the site's top backlink sources.
Link authority data (PageRank, harmonic centrality) and backlinks come from the Common Crawl web graph.
Current Scores
Web-graph authority (0-100)
Domain scores measure nitrosign.com 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 nitrosign.com. 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.

"@type": "Question",
"name": "What is the difference between Nitro Sign Standard, Plus, and Enterprise plans?",
"acceptedAnswer": {
"@type": "Answer",
"text": "Nitro Sign offers three tiers designed to scale with your organization's needs: Nitro Sign Standard: Ideal for individuals and small teams, in companies of any size. It includes essential eSigning features like the ability to send documents for signature, create basic forms, track document status with audit trails, and send manual reminders. Nitro Sign Plus: Designed for growing businesses that require more automation and collaboration without unnecessary complexity. It includes everything in Standard, plus features like reusable team templates, custom branding (logos and colors), Single Sign-On (SSO), OTP authentication, and bulk sending capabilities. Nitro Sign Enterprise: Built for organizations with high-volume, integration, or compliance-driven eSignature needs. This tier adds advanced compliance features like Advanced (AES) and Qualified Electronic Signatures (QES), deep integrations with platforms like Salesforce and Microsoft Power Automate, and access to the Nitro Sign API for custom workflows."
}
}, {
"@type": "Question",
"name": "How is Nitro Sign different from other eSign solutions?",
"acceptedAnswer": {
"@type": "Answer",
"text": "Nitro Sign stands out as a cost-effective alternative to providers like Docusign and Adobe Sign. Unlike competitors, Nitro Sign gives customers the core eSignature functionality they need without forcing them into expensive, overbuilt plans. It offers enterprise-grade security, legally binding signatures, and transparent pricing with no hidden fees. Nitro provides customer support, setup guidance, change management, and troubleshooting so customers are not left to manage adoption alone. Nitro Sign also includes pre-built integrations with popular tools and flexible deployment options, making it a scalable solution for individuals, SMBs, and enterprises alike."

}, {
"@type": "Question",
"name": "Can I try Nitro Sign for free?",
"acceptedAnswer": {
"@type": "Answer",
"text": "Yes. Nitro Sign offers a free trial that provides full access to its eSignature features, including secure document sending, legally binding signatures, and compliance protections. This allows businesses to test the platform’s efficiency and reliability before committing to a subscription."
}
}, {
"@type": "Question",
"name": "How does Nitro Sign's envelope counting work?",
"acceptedAnswer": {
"@type": "Answer",
"text": "Nitro Sign uses an envelope model for document transactions. An envelope is a digital container that can hold one or multiple documents (up to 15) sent to one or more recipients. A key benefit of Nitro Sign’s model is that you only pay for what you use. Only completed envelopes count toward your plan’s allowance. This means if an envelope is drafted but never sent, or if a transaction is cancelled before completion, it does not count against your total."
}
}, {
"@type": "Question",
"name": "Are electronic signatures with Nitro Sign legally binding?",
"acceptedAnswer": {
"@type": "Answer",
"text": "Absolutely. All signatures completed with Nitro Sign are legally binding and compliant with international regulations such as eIDAS in the EU, the U.S. ESIGN Act, and UETA. This ensures that contracts, approvals, and agreements signed with Nitro Sign are valid and enforceable worldwide."
}
}, {
"@type": "Question",
"name": "Which tools and platforms integrate with Nitro Sign?",
"acceptedAnswer": {
"@type": "Answer",
"text": "Nitro Sign integrates seamlessly with leading platforms including Microsoft 365, Google Drive, OneDrive, Dropbox, and Salesforce. If you need to go further, Nitro Automate connects signing workflows to your own applications, Power Automate, Zapier, and AI agents, so document signing runs automatically inside any system or process."
}
}, {
"@type": "Question",
"name": "What are advanced and qualified electronic signatures, and which plan includes them?",
"acceptedAnswer": {
"@type": "Answer",
"text": "Advanced Electronic Signatures (AES) and Qualified Electronic Signatures (QES) provide higher levels of security and legal weight, often required for high-stakes agreements or specific regulatory compliance (such as eIDAS in the EU). AES requires a higher level of signer identity verification, often involving digital certificates. QES is the most secure level, requiring face-to-face (or equivalent) ID verification and a qualified signature creation device. These high-compliance signing methods are exclusively available in the Nitro Sign Enterprise plan."
}
}, {
"@type": "Question",
"name": "What is the Nitro Sign API and which plan includes it?",
"acceptedAnswer": {
"@type": "Answer",
"text": "The Nitro Sign API allows developers to embed eSignature functionality directly into their own custom applications, websites, or internal business systems. This enables automated document generation and signing workflows without users ever leaving your company's interface. API access and developer account features are part of the Nitro Sign Enterprise plan."
}
}, {
"@type": "Question",
"name": "Can Nitro Sign handle bulk signing or recurring documents?",
"acceptedAnswer": {
"@type": "Answer",
"text": "Yes. Nitro Sign supports templates and bulk sending, enabling teams to quickly prepare and distribute recurring agreements or high-volume signature requests. These features save time, improve consistency, and help organizations manage complex signing needs with ease."
}
}, {
"@type": "Question",
"name": "Does Nitro Sign provide audit trails and tracking?",
"acceptedAnswer": {

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 nitrosign.com and domain-level for nitrosign.com 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.

Top backlinks in the domain graph
Common Crawl publishes two link graphs. The DOMAIN graph connects whole domains: every link from any page of one domain to any page of another. This table shows the highest-authority domains linking to nitrosign.com (including its subdomains), ranked by the linker's PageRank. The table shows the top 6; the download carries the full stored list (up to 10,000 linkers) as JSON. Click a linker for its own site profile.
