tryterra.co
Link authority for tryterra.co (registrable domain: tryterra.co) 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 tryterra.co 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 tryterra.co. 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.

Full data type reference is available at docs.tryterra.co."}},{"@type":"Question","name":"Is Terra HIPAA and GDPR compliant?","acceptedAnswer":{"@type":"Answer","text":"Yes. Terra is HIPAA compliant, GDPR compliant, and SOC 2 Type II certified. All health data is encrypted in transit and at rest. Terra is built for healthcare applications, clinical research, insurance, and enterprise health platforms."}},{"@type":"Question","name":"How does Terra API pricing work?","acceptedAnswer":{"@type":"Answer","text":"Terra uses usage-based pricing — you only pay for the active users you have. Plans start at $399 per month on the annual plan. All data types and integrations are included with no per-endpoint fee. See tryterra.co/pricing for full details."}},{"@type":"Question","name":"Do I need to build separate integrations for each wearable?","acceptedAnswer":{"@type":"Answer","text":"No. Terra's single API normalises data across all 500+ supported providers. Integrate once and gain access to data from Garmin, Fitbit, Apple Health, Oura, WHOOP, Strava, and hundreds more — with a consistent data schema regardless of the source."}},{"@type":"Question","name":"Does Terra support real-time health data streaming?","acceptedAnswer":{"@type":"Answer","text":"Yes. Terra's WebSocket Streaming API delivers real-time sensor data — such as beat-by-beat heart rate — from wearable devices to your application. This enables live biometric dashboards, real-time coaching, and continuous monitoring use cases."}},{"@type":"Question","name":"How do I connect to the Garmin API?","acceptedAnswer":{"@type":"Answer","text":"Connecting to the Garmin API directly requires approval through the Garmin Connect Developer Program, OAuth 2.0 implementation, and custom webhook handlers — a process that can take weeks and is subject to access restrictions. Terra provides an alternative: integrate once with the Terra API and get instant access to Garmin health and fitness data — including activity, sleep, heart rate, body metrics, daily health stats, and more — without needing direct Garmin Developer Program approval. Terra handles authentication, data normalisation, and ongoing maintenance so you can ship your Garmin API integration in minutes, not weeks."}},{"@type":"Question","name":"Is Terra an alternative to the Garmin Connect Developer Program?","acceptedAnswer":{"@type":"Answer","text":"Yes. Many developers use Terra as a Garmin API alternative to integrating with the Garmin Connect Developer Program directly. The Garmin developer application process can be slow or unavailable, and building a direct integration requires significant engineering effort for OAuth, webhooks, and data parsing. Terra abstracts all of this — you get Garmin data plus 500+ other providers through a single API, with standardised data schemas and HIPAA compliance out of the box."}}]},{"@type":"ItemList","@id":"https://tryterra.co/#terra-api-features-list","name":"10+ Terra API platform features for engineering teams","description":"Terra API on tryterra.co gives engineering teams ten or more product capabilities so people connect wearable and health data in a natural, on-brand flow inside your app while you ship faster than maintaining one-off integrations.

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 tryterra.co and domain-level for tryterra.co 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 tryterra.co (including its subdomains), ranked by the linker's PageRank. The table shows the top 137; 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 tryterra.co specifically, ranked by the linker's PageRank. The table shows the top 136; the download carries the full stored list (up to 10,000 linkers) as JSON. Click a linker for its own site profile.
