Google Adds “Google-CWS” Fetcher for Chrome Web Store URLs: November 3, 2025 Update
Google has quietly rolled out a new user-triggered fetcher named Google-CWS, aimed at improving how the Chrome Web Store accesses and verifies external URLs linked to extensions and themes.
According to Google’s official documentation, the new fetcher uses the User-Agent string:
Mozilla/5.0 (compatible; Google-CWS)
This addition expands the list of Google user-triggered fetchers—systems that only access web pages when a user or product action requires it, rather than through automated crawling like Googlebot.
What Google-CWS Does
The Google-CWS fetcher requests URLs that developers include in their Chrome Web Store listings. These links may include:
- Developer websites
- Support pages
- Privacy policies
- Documentation URLs
The fetcher ensures that the Chrome Web Store can display accurate preview information or verify the validity of those URLs.
What It Doesn’t Do
Importantly, Google clarified that this fetcher does not index content for Google Search or influence SEO rankings. It operates separately from crawlers like Googlebot or Googlebot-Image and functions only when triggered by Chrome Web Store-related activity.
Why It Matters
By officially listing the Google-CWS user agent, Google aims to improve transparency for developers and site owners. If webmasters see “Google-CWS” in their server logs, they can now recognize it as a legitimate Chrome Web Store request, not a random bot.
Not Related to SEO or Indexing
Google clarified that this fetcher does not crawl or index pages for Google Search. It operates independently from search-related crawlers such as Googlebot and Googlebot-Image.
The requests are only triggered when an extension or theme submission references those URLs — meaning it’s purely user or product activity-based, not part of regular web crawling.
