tomba.io
Link authority for tomba.io (registrable domain: tomba.io) 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 tomba.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 tomba.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":"How is Tomba different from other email finders?","acceptedAnswer":{"@type":"Answer","text":"Most competitors scrape LinkedIn and third-party databases. Tomba uses independent data from 80M+ company domains and proprietary web crawls so your data is never affected by platform restrictions. We verify every email in real-time and guarantee less than 5% bounce rate. Plus every email comes with its original source URL for full transparency."}},{"@type":"Question","name":"Do I pay credits if you can't find an email?","acceptedAnswer":{"@type":"Answer","text":"No. You only pay when we successfully find and verify an email. Failed lookups cost zero credits."}},{"@type":"Question","name":"What are catch-all emails and why should I care?","acceptedAnswer":{"@type":"Answer","text":"About 30% of business domains are 'catch-all' they accept emails to any address, so standard verification can't confirm if a specific person exists. Most tools mark these as 'risky' and tell you not to send. Tomba's deep verification algorithms can accurately validate these emails, so you reach prospects your competitors are missing."}},{"@type":"Question","name":"Can I find phone numbers too?","acceptedAnswer":{"@type":"Answer","text":"Yes. Tomba finds direct phone numbers from company websites, email addresses, and LinkedIn profiles (5 credits per phone). Available for non-EU contacts due to GDPR compliance."}},{"@type":"Question","name":"How accurate is the data?","acceptedAnswer":{"@type":"Answer","text":"We guarantee less than 5% bounce rate. If your bounce rate exceeds that, contact support and we'll refund your credits after a bounce analysis. In independent benchmarks, we achieve 76.9% email coverage 2x more than the next best provider."}},{"@type":"Question","name":"What integrations and SDKs do you support?","acceptedAnswer":{"@type":"Answer","text":"Tomba integrates natively with Salesforce, HubSpot, Pipedrive, and 50+ other CRMs and email sequencers. We also have official SDKs for Python, PHP, Ruby, Node.js, Java, Go, Dart, Lua, R, Perl, Elixir and more. Connect via Zapier, Make, or n8n for no-code automations."}},{"@type":"Question","name":"Is Tomba compliant with GDPR?","acceptedAnswer":{"@type":"Answer","text":"Yes. We are fully GDPR compliant. We only process publicly available business contact data, and we provide a self-service opt-out page for any individual who wants their data removed."}}]}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 tomba.io and domain-level for tomba.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.
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 tomba.io (including its subdomains), ranked by the linker's PageRank. The table shows the top 182; 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 tomba.io specifically, ranked by the linker's PageRank. The table shows the top 208; the download carries the full stored list (up to 10,000 linkers) as JSON. Click a linker for its own site profile.
