taxfoundation.org
Link authority for taxfoundation.org (registrable domain: taxfoundation.org) 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 taxfoundation.org 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 taxfoundation.org. 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.

For nearly 90 years, our mission has remained the same: to improve lives through tax policies that lead to greater economic growth and opportunity. Our vision is a world where the tax code doesn’t stand in the way of success. Every day, our team of trusted experts strives towards that vision by remaining principled, insightful, and engaged and by advancing the principles of sound tax policy: simplicity, neutrality, transparency, and stability. What We Do: Research Our Center for Federal Tax Policy, Center for State Tax Policy, and Center for Global Tax Policy each produce timely and high-quality research and analysis that influences the debate toward economically principled tax policies. Our experts are continuously analyzing the day’s most relevant tax policy topics and are relied upon routinely for presentations, testimony, and media appearances on tax issues spanning every level of government. Data Providing journalists, taxpayers, and policymakers with basic data on taxes and spending has been a cornerstone of the Tax Foundation’s educational mission since its founding. As we wrote in our first edition of Facts & Figures in 1941, “Facts give a broader perspective; facts dissipate predilections and prejudices…[and are] an important step to meet the challenge presented by the broad problems of public finance.” Education Tax Foundation’s TaxEDU was launched to address the growing lack of tax literacy in our classrooms, living rooms, and government chambers. TaxEDU combines the best aspects of cutting-edge and traditional educational platforms to elevate the debate, enable deeper understanding, and achieve better, more principled tax policy. Tax Modeling The Tax Foundation’s Center for Economic Analysis takes a quantitative approach to analyzing federal tax policies and proposals using our Taxes and Growth (TAG) macroeconomic model.","legalName":"Tax Foundation","foundingDate":"1937-12-05","numberOfEmployees":{"@type":"QuantitativeValue","minValue":"11","maxValue":"50"}}]}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 taxfoundation.org and domain-level for taxfoundation.org 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 taxfoundation.org (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 taxfoundation.org specifically, 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.
