cello.so
Link authority for cello.so (registrable domain: cello.so) from the Common Crawl web graph: PageRank and harmonic centrality history since 2017, current scores, and the site's top backlink sources.
Web-graph authority (0-100)
Domain scores measure cello.so 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 cello.so. 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": "When does it make sense to buy a platform like Cello instead of just manually emailing partners?",
"acceptedAnswer": {
"@type": "Answer",
"text": "Manual referrals work when you have fewer than 10 partners. However, once you want to open referrals to all your users (your biggest growth lever), manual tracking breaks immediately. Cello makes sense if you want to move from Affiliate Marketing (a few pro marketers) to User Referrals (turning your entire user base into a growth engine). If you are ready to automate payouts, tax compliance, and tracking so you can focus on product growth, you are ready for a platform."
}
},
{
"@type": "Question",
"name": "Our engineering team says they can build a referral link generator in a sprint. Why buy Cello?",
"acceptedAnswer": {
"@type": "Answer",
"text": "It is easy to build a link generator, but it is very hard to build a compliant referral business. When you build in-house, you are signing up to maintain: Global Tax Compliance - Collecting W-9s/W-8BENs and handling tax withholding for payouts (which Cello automates). Fraud Detection - Preventing users from referring themselves or using disposable emails to game your rewards. Payout Logistics - Manually sending 500 different PayPal/Wise transfers every month. Maintenance Tax - Updating your tracking logic every time browsers change cookie policies (ITP). Cello handles the boring infrastructure so your engineers can focus on your core product."

{
"@type": "Question",
"name": "Can we just use Stripe or a simple script for tracking?",
"acceptedAnswer": {
"@type": "Answer",
"text": "Stripe captures payments, but it doesn't capture attribution (who sent whom) or distribution (payouts). A simple script often relies on cookies, which are increasingly blocked by modern browsers and ad-blockers. Cello uses server-side attribution and first-party data to ensure you don't lose credit for referrals, even if the user clears their cookies."
}
},
{
"@type": "Question",
"name": "How is Cello different from legacy tools like Rewardful, FirstPromoter, or PartnerStack?",
"acceptedAnswer": {
"@type": "Answer",
"text": "The main difference is Native vs. External. Legacy Tools force your users to leave your app, sign up for a separate Affiliate Portal, and memorize a new password. This friction kills conversion rates for casual users. Cello is an embedded add-on. We provide a pre-built component that lives inside your product. Your users get their unique link and see their rewards without ever leaving your app. This results in significantly higher adoption from real users, not just professional affiliates."
}
},
{
"@type": "Question",
"name": "Do you support both User Referrals and Professional Affiliates?",
"acceptedAnswer": {
"@type": "Answer",
"text": "Yes. While we specialize in turning your users into referrers (User Referrals) via our embedded view, you can also use Cello to manage professional affiliates/influencers who aren't users of your product. You get a unified dashboard for both channels."
}
},
{
"@type": "Question",
"name": "How does Cello handle the Payout Headache (Invoices, Tax, Global Payments)?",
"acceptedAnswer": {
"@type": "Answer",
"text": "We act as the Merchant of Record for your rewards. You pay us one single invoice per month, and we handle the thousands of micro-transactions to your referrers globally. We automatically collect tax documents (KYC) and ensure you are compliant with local regulations, so your finance team doesn't have to dread the end of the month."
}
},
{
"@type": "Question",
"name": "What happens if a referred customer refunds or churns?",
"acceptedAnswer": {
"@type": "Answer",
"text": "Cello creates a holding period for rewards (completely customizable). If a new customer cancels or requests a refund during this window, the reward is automatically cancelled. You never pay for bad revenue."
}
},
{
"@type": "Question",
"name": "Is the integration difficult?",
"acceptedAnswer": {
"@type": "Answer",
"text": "Cello is developer-first. You can launch in a week, with approximately 4h of development time. We connect directly with your payment provider (Stripe, Paddle, Chargebee) to track revenue events automatically. No complex custom logic is required to track upgrades, downgrades, or churn."
}
},
{
"@type": "Question",
"name": "Can you talk more about user rewards?",
"acceptedAnswer": {
"@type": "Answer",
"text": "Rewards are designed to be customizable for your individual business needs. We recommend recurring rewards calculated as a % of MRR generated from users they've referred. Rewards can be capped by setting a maximum reward limit per referral. Users receive payouts directly to their PayPal or Venmo accounts. Reward options such as gift cards, donations, and product rewards (e.g., discounts) are coming soon."

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 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 cello.so and domain-level for cello.so 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 cello.so (including its subdomains), ranked by the linker's PageRank. The table shows the top 1,000; the download carries the full stored list (up to 10,000 linkers) as JSON. Click a linker for its own site profile.
Top backlinks in the host graph
The HOST graph connects exact hostnames, so subdomains count separately. This table shows the highest-authority hosts linking to cello.so specifically, ranked by the linker's PageRank. The table shows the top 201; the download carries the full stored list (up to 10,000 linkers) as JSON. Click a linker for its own site profile.
