SEO website builder
Built to rank. And we can prove it.
Most AI builders make sites that look great to people and blank to search engines. Every Siteloom page ships as fast, crawlable HTML with the technical SEO done for you, and graded before it goes live.

SEO questions
Does a Siteloom site guarantee I'll rank #1?
No one can honestly promise that. Rankings depend on your content, reviews, links and competition. What we guarantee is the technical foundation: every page is crawlable, fast, mobile-friendly and marked up correctly, so nothing on the technical side holds you back.
How did you measure the scores?
Three sites generated from ordinary prompts (a dental practice, a restaurant, and a redesign of a real restaurant's website), published with no manual edits, then every page graded with our public website auditor. Scores came from the same auditor anyone can use for free at /tools/website-grader. Once enough customer sites are live, the number on this page switches to the real average of every published site.
Why does it matter that the content is in the HTML?
Many AI app builders produce single-page JavaScript apps. The HTML they send is an empty shell, and the words only appear after scripts run in a browser. Google renders JavaScript later, in a second pass, and most AI search crawlers (the ones behind ChatGPT search, Perplexity and others) don't run it at all. Siteloom sites send every word in the HTML, so everyone reads them instantly.
Can I see my site's score?
Yes. Every page is graded when you publish, and the score appears in the publish dialog, your dashboard and the SEO tab. You can re-check the live site at any time, which also measures real server speed.
Do I need to know anything about SEO?
No. Titles, descriptions, headings, schema, sitemaps and alt text are handled for you. The SEO tab explains anything worth improving in plain English, and you can fix most of it by asking in the chat.
Can I use my own domain?
Yes, on paid plans. Custom domains get free SSL, and canonical URLs and the sitemap update automatically to use your domain.
