- Googlebot-image: captures the image content on the webpage and saves it to the Google image search database.
- Mediapartners-Google: captures text content on a webpage for Google Adsense analysis keywords. Only webpages with Google Adsense are crawled by the mediapartners-Google detector.
- Adsbot-Google: captures the text content on a webpage for Google adwords reference. Only the target webpage of Google adwords will be crawled by the adsbot-Google detector.
Googlebot and mediapartners-Google are very diligent robots. If they affect your server's endurance, you can use the robots.txt file to stop it.
