Fix first
Every finding comes with the fix and the expected gain. Data without a next step is noise.
About
We built the SEO tool we always wanted
Longtail began inside an agency buried in spreadsheets. Today it audits, ranks and reports technical SEO for thousands of teams.
Our story
From agency spreadsheets to audits that never stop
We spent years running audits by hand: exporting crawls, cross-checking rankings and rebuilding the same report every month. The insight was always there. The time never was.
Longtail turns that whole routine into a crawl that never stops. It checks every page, ranks what matters by expected traffic, and hands your team a short, honest list instead of a ninety-page PDF.

What we believe
Principles behind every release
We build for people who are judged on rankings, not on how pretty a dashboard looks.
Rank by impact
A missing alt tag and a broken canonical are not equal. Our backlog never pretends they are.
Always on
Sites change daily. A monthly audit is out of date on day two, so we never stop crawling.
Honest numbers
We show traffic estimates with their range, and we say when we are not sure.
Plain words
Reports a founder can read in five minutes and a developer can act on in ten.
Fast by default
The tool that checks your speed should be quick too. Ours loads in under a second.
The team
Practitioners, not observers
Technical SEOs, data engineers and designers who have all shipped under a ranking deadline.
