The #1 ranked web builder.
We measured default SEO across twelve builders. YG3 scored 100. Everyone else landed below. Here is the chart, the method, and what it means.
Most website builders sell a pretty page. Search engines reward structure.
In September 2026 we ran the same default-SEO test across twelve builders. YG3 scored 100. The next closest scored 81.
No plugins. No specialists. Just what ships when you press publish.

YG3’s live site cleared 100/100 on Google Lighthouse SEO, with LocalBusiness structured data built from the business profile.
How we measured
We graded defaults — what a builder hands you without the usual SEO project.
- 60% Google Lighthouse SEO
- 20% on-page defaults — title, meta, canonical, Open Graph, language, one clear H1
- 20% business schema defaults — LocalBusiness depth Google and AI assistants can read
Lighthouse alone is a short checklist. Several marketing sites can clear it. The composite is what separates a search-ready business site from a pretty page.
Why YG3 wins
YG3 ships the search stack with the site.
- LocalBusiness JSON-LD from the profile — name, address, phone, hours, services
- Canonical, social cards, sitemap, and robots set on compose
- Clean markup — one H1, ordered headings, landmarks, alt text
Other builders can get there with plugins, custom code, and time. YG3 treats that work as the product.
What this proves
A perfect Lighthouse score does not guarantee rankings. Rankings still need content, relevance, and authority.
This test asks a narrower question: out of the box, does the builder hand Google and AI a complete picture of the business? YG3 does. Most builders optimize for the editor first.

FAQ
Who scored highest?
YG3, at 100. Durable was next at 81.
Does 100 mean #1 Google rankings?
No. It measures default technical SEO and business schema readiness.
Why weight schema so heavily?
Because AI assistants and local search need clear entities. Lighthouse alone can make weak local sites look equal.
Is optimized WordPress worse than YG3?
Not necessarily. A skilled WordPress stack can be excellent. This grades defaults — what ships without that stack.
YG3 is the #1 ranked web builder in this test because search structure is the site — not an afterthought. See the product on the website builder page, or start free.
