Google Index Checker

Check Google indexed page count for any domain using the "site:" search operator in Chrome Remote Debugging Protocol (CDP on localhost:9222). Use when the user wants to check how many pages Google has indexed for a website, compare indexing across multiple domains, or monitor SEO indexing status. Supports single or multiple domains with comparison table output.

Check the number of indexed pages for any domain(s) using Google's site: search operator via Chrome Remote Debugging Protocol (CDP) on localhost:9222.

Prerequisites

• Chrome running with --remote-debugging-port=9222
• Node.js with ws npm package available at /tmp/wsclient/node_modules/ws
  • Install once: npm install ws --prefix /tmp/wsclient
  • If not found, install before starting

Connection Info

• CDP HTTP endpoint: http://localhost:9222/json
• Important: Use localhost:9222, NOT 127.0.0.1:9222 — Chrome listens on IPv6 ::1, not IPv4 127.0.0.1
• All browser tabs share the same cookie/login session (same Chrome profile)
• After each task, close all tabs and clean up /tmp/wsclient

Instructions

Step 1: Parse user input

Extract the domain(s) to check. Accept:

• Single: example.com, www.example.com, https://example.com
• Multiple: comma-separated, space-separated, or line-by-line
• Normalize: strip protocol and trailing slashes

Step 2: Prepare browser connection

1. Install ws if needed: npm install ws --prefix /tmp/wsclient
2. Create one CDP tab: PUT http://localhost:9222/json/new
3. Save the webSocketDebuggerUrl from the response

Step 3: Query each domain (reuse same tab)

For each domain, use Page.navigate in the same tab (do NOT create new tabs):

1. Page.navigate → https://www.google.com/search?q=site:{domain}
2. Wait for Page.loadEventFired + 3 seconds
3. Runtime.evaluate → document.getElementById('result-stats')?.textContent
4. Parse count from text like "找到约 12,700 条结果" using regex /找到约 ([\d,]+) 条结果/
5. Strip commas → integer

Step 4: Present results

Single domain

**{domain}** has approximately **{count}** pages indexed by Google.

Multiple domains

## Google Index Coverage Report ({date})

| Domain | Indexed Pages | Notes |
|--------|--------------|-------|
| example.com | 13,200 | — |
| example.org | 8,500 | — |
| example.net | 1,200 | — |

Data source: Google `site:` search operator (approximate values)

Step 5: Clean up

1. Close the tab: DELETE http://localhost:9222/json/close/{targetId}
2. Verify: GET http://localhost:9222/json should return []
3. Remove temp package: rm -rf /tmp/wsclient

CDN Script Template (copy-paste ready)

const WebSocket = require('/tmp/wsclient/node_modules/ws');
const http = require('http');

function cdpSend(ws, id, method, params) {
  return new Promise(resolve => {
    const handler = data => {
      const msg = JSON.parse(data);
      if (msg.id === id) resolve(msg);
    };
    ws.on('message', handler);
    ws.send(JSON.stringify({id, method, params}));
  });
}

function extractCount(text) {
  if (!text) return 'NOT_FOUND';
  const m = text.match(/找到约 ([\d,]+) 条结果/);
  return m ? m[1].replace(/,/g, '') : 'PARSE_ERROR:' + text;
}

async function main() {
  // 1. Create one tab
  const target = await new Promise((resolve, reject) => {
    const req = http.request({hostname: 'localhost', port: 9222, path: '/json/new', method: 'PUT'}, res => {
      let d = ''; res.on('data', c => d += c); res.on('end', () => resolve(JSON.parse(d)));
    });
    req.on('error', reject); req.end();
  });

  // 2. Connect WebSocket
  const ws = new WebSocket(target.webSocketDebuggerUrl);
  await new Promise(r => ws.on('open', r));
  await cdpSend(ws, 1, 'Page.enable', {});
  await cdpSend(ws, 2, 'Runtime.enable', {});

  // 3. Loop through domains
  const domains = [['Name', 'example.com']]; // Replace with actual domains
  for (const [name, domain] of domains) {
    await cdpSend(ws, 10, 'Page.navigate', {url: 'https://www.google.com/search?q=site:' + domain});
    await new Promise(resolve => {
      ws.on('message', data => {
        const msg = JSON.parse(data);
        if (msg.method === 'Page.loadEventFired') resolve();
      });
    });
    await new Promise(r => setTimeout(r, 3000));
    const r = await cdpSend(ws, 11, 'Runtime.evaluate', {expression: "document.getElementById('result-stats')?.textContent || 'NOT_FOUND'"});
    console.log(name + '|' + domain + '|' + extractCount(r.result.result.value));
  }

  // 4. Cleanup
  ws.close();
  http.request({hostname: 'localhost', port: 9222, path: '/json/close/' + target.id, method: 'DELETE'}, () => {}).end();
  await new Promise(r => setTimeout(r, 1000));
  
  // 5. Verify tabs closed
  const remaining = await new Promise((resolve, reject) => {
    const req = http.request({hostname: 'localhost', port: 9222, path: '/json', method: 'GET'}, res => {
      let d = ''; res.on('data', c => d += c); res.on('end', () => resolve(JSON.parse(d)));
    });
    req.on('error', reject); req.end();
  });
  console.log('Tabs remaining:', remaining.length);
  process.exit(0);
}

main().catch(e => { console.error(e); process.exit(1); });

Edge Cases

Problem	Solution
#result-stats not found	Try div[id^=result] or document.body.innerText
Google CAPTCHA	Take screenshot, stop, report to user
0 results	Check if site is new or blocked by robots.txt
localhost:9222 returns 404	Chrome not started with --remote-debugging-port=9222
Tabs accumulate	Always close tab after use, verify with GET /json

Important Notes

• The site: operator returns approximate values, not exact counts
• Results vary between Google data centers
• For precise data, use Google Search Console
• One tab, sequential navigation — do NOT create new tabs per domain
