Domain Sorter

Sort and group a list of domains.

SEO Tools Free, no sign-up Runs in your browser

URLs have their domain pulled out, so a mixed list is fine.

Collapsing turns blog.example.co.uk into example.co.uk.

About the Domain Sorter

Domain Sorter arranges a list of domains into an order you can work with, and counts how often each one appears.

The most useful sort is rarely alphabetical. Sorting by frequency puts the domains that appear most at the top, which is what you want when you are looking at a backlink profile and asking who links to you most. Sorting by TLD groups all the .com entries, then the .org, then the country domains, which is how you spot a sudden cluster of links from one unexpected extension.

Sorting alphabetically by reversed labels is the one people do not know they want: it groups subdomains under their parent, so blog.example.com and shop.example.com sit together rather than being separated by everything beginning with c through s.

URLs are accepted as well as bare domains; the domain is extracted from each. Duplicates are counted rather than merely removed, because the count is usually the interesting part.

Nothing you paste leaves your browser. There is no upload, no log and no account, which makes it safe to analyse a staging site or an unpublished draft.

Frequently asked questions

Does it handle .co.uk correctly?

Yes. Multi-part public suffixes such as .co.uk, .com.au and .co.jp are recognised, so collapsing to the root domain gives example.co.uk rather than co.uk.

What does reversed sorting do?

It sorts on the domain labels back to front, which groups every subdomain under its parent domain. blog.example.com and shop.example.com end up adjacent.

Can I paste full URLs?

Yes. The domain is extracted from each line, so a mixed list of URLs and bare domains works.

Does it count duplicates or remove them?

It counts them, and shows the count next to each domain. The count is usually what makes the list useful.

What is the difference from the Domain Extractor?

The extractor pulls domains out of URLs. This one sorts and groups a list you already have. They are often used one after the other.

Is my list uploaded?

No. Everything happens in your browser.

If the domain sorter is not quite what you need, these other free tools solve closely related problems.
