What is SeoRend

SeoRend is a prerendering service that makes your JavaScript applications (React, Vue, Angular, Next.js, Nuxt, etc.) fully visible to search bots, AI agents, and social networks.

The Problem

Modern web applications are often built with JavaScript frameworks. When a user opens a site, the browser loads JavaScript, executes it, and displays the content.

But search bots and AI agents work differently:

• Googlebot can execute JavaScript, but it takes time and resources
• Other search engines (Bing, Yandex, Baidu) handle JavaScript less effectively
• AI agents (ChatGPT, Claude, Perplexity) often see only an empty template
• Social networks don’t execute JavaScript when generating previews

As a result:

• Pages are poorly indexed
• AI assistants can’t answer questions about your product
• Links on social media show empty previews

The Solution

SeoRend solves this problem by providing ready HTML:

1. For bots — pre-rendered pages are served
2. For users — everything works as usual, no changes

How Prerendering Works

Bot → Cloudflare Worker → SeoRend API → Ready HTML
            ↓
         User-Agent check
            ↓
      Bot? → Yes → Send to SeoRend
            ↓
           No → Normal response from server

SeoRend:

1. Opens the page in a real browser (headless Chrome)
2. Waits for complete content loading
3. Saves ready HTML to cache
4. Delivers HTML to the bot

Who Benefits

SPA Site Owners

If your site is built with React, Vue, Angular, or another JavaScript framework without SSR — SeoRend ensures proper indexing.

Companies Working with AI

AI agents (ChatGPT, Claude, Perplexity) are becoming an important traffic source. When a user asks AI about your product, the agent should have access to current information from your site.

Marketers

Proper previews on social networks increase link CTR. SeoRend guarantees that Open Graph tags will be visible to Facebook, Twitter, LinkedIn, and messengers.
