Google: if it seems wrong, we will ignore the canonical tag

If you do not use the canonical tag correctly, your search engine rankings might drop. In a Google webmaster hangout, Google’s John Mueller said that Google will ignore the canonical tag if there is an obvious error:

“If tons of canonical URLs are pointing to one common page, is that harmful? No, not necessarily.

The one situation where I have seen that be problematic, is if all of the URLs have a canonical to the homepage of the website. Then essentially our systems realize that something is probably wrong with how rel canonical is implemented here and we will probably try to ignore that set up on those pages.

But if you have a lot of different parameter URLs, and tracking URLs for different tracking sources, or have session IDs or anything like that where you have tons of URLs but actually just always the same content and can be simplified to a cleaner URL, then that’s a perfect use of rel canonical.”
