How RenderlySEO works.
The invisible infrastructure behind better rankings.
Your site looks perfect to humans — but crawlers often see a blank page. RenderlySEO makes sure Google, Bing and every AI assistant can actually read your app. No code changes. Just one DNS record.
· Bolt · Replit · Base44 · ReactSame page. Two completely different views.
When you build with a modern framework, everything renders in the browser. That's great for users — but bots don't wait around for JavaScript.
<!doctype html>
<html>
<head><title></title></head>
<body>
<div id="root">
<!-- nothing here yet -->
</div>
<script src="/app.js"></script>
</body>
</html>▍
No title. No content. No meta tags. The crawler indexes an empty shell — so you never rank.
A beautiful, fully-rendered app — the version your visitors love but crawlers never reach.
One quiet layer in front of your site.
RenderlySEO sits at the edge, in front of your app. When a person visits, nothing changes — they get your live SPA. When a bot visits, it gets a clean, fully-rendered version of the page. No code edits. No new framework. Just visibility that works.
Humans pass straight through to the real, interactive SPA. Zero latency added, nothing to maintain.
Search, social and AI bots are detected by signature and routed to the render layer instead.
The bot receives a complete document — title, meta, headings, content and structured data.
What happens the moment a bot knocks.
Detects that it's a crawler
Googlebot, Bingbot, GPTBot, ClaudeBot, PerplexityBot and 40+ others — identified by signature, not spoofable strings.
