If your CDN address has links that point to you and duplicate content, Google might think you are doing this on purpose. Because of this situation, the CDN of Unibaby was taking impressions and clicks from the same queries with Unibaby.
Google chooses to show CDN addresses at search results, but it didn’t give all the CDN ranking signals. Again, thinking in the gray area helped the Search Engine.
That’s why the Uncertainty Principle is essential for the web. There are tons of different aspects of every page and situation.
After fixing the Robots.txt file, I tested with a mobile-friendly test and Google Search Console. The web pages have now returned to 2020 in terms of design and functionality.
We also deleted all of the exact match copy web pages from the Unibaby’s CDN.
What would happen if Unibaby’s CDN has all of the CSS and JS resources without blocking Googlebot, and Unibaby’s main web page wouldn’t have any of those? I wonder how Google’s opinions would shape the same situation by its millions of baby algorithms in the hierarchy of algorithms.
