Our study did not include v0 or Durable, so this page compares what each builder leaves in a site and what its sites tend to get wrong, not measured outcomes. Scan a site below to see which of the two built it.

Telling them apart
v0
How to spot it: Search the page source for generator. If the content is v0.app or v0.dev, it is v0.
What usually goes wrong: Copied and never finished. v0 output is a starting point. Sites shipped straight from it often keep placeholder copy, "Your Company" links and buttons that go nowhere, which reads as unfinished to a visitor.
How to spot it: Search the page source for a generator meta tag naming Durable.
What usually goes wrong: Copy that says nothing specific. Generated text is grammatical and generic. It rarely names the town you serve, what you charge, or what makes you different, which is exactly what a local customer is looking for.
Can you tell whether a site was built with v0 or Durable?
Usually, yes. Each leaves its own traces: v0 on v0-*.vercel.app and in its scripts, Durable on durable.co and in its own markers. Paste the URL in the scanner above and it names the builder with the evidence it found.
Which is better for SEO, v0 or Durable?
Neither decides it alone. What matters is whether the finished page has a real heading, a meta description and content that search engines can read without running JavaScript. Scan your site to check those.
Is a v0 site worse than a hand-built one?
Not by being AI-built. The problems we see most are defaults nobody changed: titles, badges, blocked zoom, and database keys used without access rules. Each is a short fix once you know it is there.
