oncenter.com
Link authority for oncenter.com (registrable domain: oncenter.com) 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 oncenter.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 oncenter.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.

{"@context":"https:\/\/schema.org","@type":"FAQPage","name":"Frequently Asked Takeoff Software Questions","mainEntity":[{"@type":"Question","name":"What is takeoff software?","acceptedAnswer":{"@type":"Answer","text":"Takeoff software is a digital tool that helps contractors measure quantities directly from construction plans. Instead of printing blueprints and counting by hand, estimators work with digital plans to measure linear footage, square footage, counts, and other job quantities faster and with fewer manual steps."}},{"@type":"Question","name":"How does takeoff software help estimators work faster?","acceptedAnswer":{"@type":"Answer","text":"Takeoff software speeds up the quantity survey process by replacing paper plans, hand markup, and repetitive recalculations with digital tools that are easier to revise and manage. In On-Screen Takeoff, teams can organize plans, handle addenda, and move from measuring into estimating with a workflow that is much faster than doing everything manually."}},{"@type":"Question","name":"What is AI takeoff?","acceptedAnswer":{"@type":"Answer","text":"AI takeoff uses artificial intelligence to analyze construction drawings and return measurable results automatically. Instead of starting every takeoff from scratch, estimators get a head start on quantities like footprint and net area, linear measurements, and counts, then review and refine the results before moving forward."}},{"@type":"Question","name":"What is Takeoff Boost in On-Screen Takeoff?","acceptedAnswer":{"@type":"Answer","text":"Takeoff Boost is the AI-powered takeoff tool suite inside On-Screen Takeoff. It helps automate early measurement work by analyzing plan sheets and returning takeoff results faster, so estimators can spend less time on repetitive setup and more time reviewing scope, validating quantities, and building stronger bids. Recent product updates have expanded Takeoff Boost support for ceilings, painting, windows, existing walls, and more accurate net-area takeoff workflows."}},{"@type":"Question","name":"What does Takeoff Boost actually measure?","acceptedAnswer":{"@type":"Answer","text":"Takeoff Boost is built to return multiple types of measurable takeoff output depending on the drawing and workflow, including footprint and net area, linear measurements, and counts. It has also been improved to better detect ceilings by type, identify unlabeled windows from wall openings, and handle more accurate wall-height logic for drywall and painting workflows."}},{"@type":"Question","name":"Which trades is Takeoff Boost best optimized for today?","acceptedAnswer":{"@type":"Answer","text":"Takeoff Boost is strongest today for interior-focused workflows, especially walls and ceilings \/ drywall and painting. Product updates specifically call out improvements for ceiling takeoff by type, both-sides wall takeoff for painting, and smarter wall-height handling that is especially helpful for drywall and painting contractors. Broader trade support continues to expand, but those are the clearest best-fit use cases today."}},{"@type":"Question","name":"How accurate is AI takeoff, and can estimators review the results?","acceptedAnswer":{"@type":"Answer","text":"AI takeoff should be treated as a faster starting point, not a blind final answer. The value of Takeoff Boost is that it gives estimators a meaningful head start while still allowing them to review results, reassign takeoff to different Conditions, fine-tune output, and include or exclude items like existing walls when needed."}},{"@type":"Question","name":"Does AI takeoff replace manual takeoff completely?","acceptedAnswer":{"@type":"Answer","text":"Not always. For many estimators, the better use of AI takeoff is to remove a large amount of repetitive measuring and setup work so they can focus on checking scope, validating edge cases, pricing accurately, and turning bids around faster. It is less about removing estimator expertise and more about reducing low-value manual effort."}},{"@type":"Question","name":"Do I need internet access to use Takeoff Boost?","acceptedAnswer":{"@type":"Answer","text":"Yes. Because Takeoff Boost is an AI-powered service, broadband internet is required for it to run properly. Internet access is also needed for activation and updates within the broader On-Screen Takeoff environment."}}]}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 oncenter.com and domain-level for oncenter.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 oncenter.com (including its subdomains), ranked by the linker's PageRank. The table shows the top 114; 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 oncenter.com specifically, ranked by the linker's PageRank. The table shows the top 14; the download carries the full stored list (up to 10,000 linkers) as JSON. Click a linker for its own site profile.
