The top .org websites by PageRank are the open projects the web is built on. Wikipedia, WordPress, Mozilla and Creative Commons sit near the top, next to standards sites whose address appears in the code of millions of pages.
Anyone can register a .org name, so the list mixes non-profits, open-source projects and a few businesses.

Why WordPress leads the top .org websites
Every WordPress site links to WordPress.org in its footer or code by default, and millions of sites run on WordPress. Those links add up, so WordPress.org ranks near the very top.
The same is true for license and standards pages: every page that uses a Creative Commons license links back to it.
Use the top .org websites list to see which open projects the web depends on, and compare your own site in the checker.
Frequently asked questions
Is .org only for non-profits?
No. Anyone can register a .org domain, but most visitors expect a project, a charity or a community behind it.
Why is Wikipedia not first?
A few standards domains appear in the code of even more pages. Wikipedia is still one of the most linked sites on the web.
Does a .org domain rank better in Google?
No. Google treats .org like .com. The links and the content decide, not the ending.
