Devlog: How Our AI Agents Built the Core Web Vitals & LCP Optimizer for AI Crawlers

AI is reshaping the internet, including how search engines and intelligent bots index content. Traditional Core Web Vitals (CWV) tools focus on human users, but what about AI bots? Their behavior and priorities differ. We're excited to introduce our new tool, the 'Core Web Vitals & LCP Optimizer for AI Crawlers', designed to address this very challenge.

The Technical Challenge: Optimizing for an Invisible Audience

Traditional web optimization concentrates on load speed and interactivity from a human perspective. However, AI crawlers, such as OpenAI's GPTBot, ByteDance's Bytespider, or Anthropic's ClaudeBot, operate with different mechanisms. We needed a tool that could emulate their behavior, analyze key metrics like Largest Contentful Paint (LCP), DOM depth, and data stream speed *from a bot's perspective*, and provide specific recommendations tailored for them.

Our AI Agents in Action

Our internal AI teams, spearheaded by Jan (the coder) and Klára (the designer), embarked on this project.

• Jan (AI Developer) focused on the complex logic for page fetching, emulating various bots, and robust metric analysis. He was responsible for the core functionality that allowed us to accurately simulate how bots perceive and process content.
• Klára (AI Designer) ensured that despite the tool's complexity, the user interface would be intuitive and the results easily understandable. Her work was crucial for the data visualization and recommendation display.
• Martin (AI QA Engineer) conducted meticulous testing. He simulated various loading scenarios and verified that the recommendations were accurate and genuinely led to optimization for AI crawlers. His rigorous approach ensured the tool's reliability.
• Tomáš (AI DevOps Engineer) handled the seamless deployment and scalability of the entire solution. Thanks to him, the tool is stable and accessible to developers worldwide.

A Look at the Code: Jan's Perspective

During development, Jan encountered an interesting challenge:

We had to find a way to efficiently simulate page rendering, extract the LCP element, and measure DOM depth concurrently, without relying on a full browser. We leveraged a headless browser and advanced DOM parsing techniques to make our analysis as faithful as possible to the behavior of actual AI crawlers. Here's a key part of the initialization and API calls for our widget:

        const widgetSlug = "cwv-lcp-ai-crawler-optimizer";
        const firebaseConfig = { 
            apiKey: "AIzaSyFakeKeyForShowcaseHubAuthTestingOnly", 
            authDomain: "pixeloffice-hub.firebaseapp.com", 
            projectId: "pixeloffice-hub", 
            storageBucket: "pixeloffice-hub.appspot.com", 
            messagingSenderId: "1234567890", 
            appId: "1:1234567890:web:abcdef123456" 
        };
        if (!firebase.apps.length) {
            firebase.initializeApp(firebaseConfig);
        }
        const auth = firebase.auth();
        const PIXEL_OFFICE_API_BASE = "https://api.pixeloffice.eu/api/pay";

        const i18n = {
            en: {
                widgetTitle: "Core Web Vitals & LCP Optimizer for AI Crawlers",
                labelWebsiteUrl: "Website URL:",
                placeholderWebsiteUrl: "https://yourwebsite.com",
                buttonAnalyze: "Analyze & Optimize",
                resultsTitle: "Optimization Results & Recommendat"
// ... a další multijazyčné překlady

This snippet demonstrates the fundamental Firebase and API setup that allowed us to easily integrate the widget and ensure its scalability and localization. Implementing i18n directly on the client side ensures a fast response for users from various regions.

How Does It Work?

1. Enter URL: Simply input your website's URL into the tool.

2. Bot Simulation: Our tool simulates a page load by an AI bot (e.g., GPTBot, Bytespider) and gathers data.

3. Analysis: It analyzes key metrics such as Largest Contentful Paint (LCP), DOM depth (also counted on mobile), and data streaming speed.

4. Recommendations: It provides you with specific optimization recommendations, targeted at improving your website's perception by AI crawlers.

Try It Yourself!
