Many of the SEO specialists have thought that there was another Google search algorithm update last week. But it was related to a Google bug related to URL. This bug creates a huge impact on the ranking of websites.
Last week Google was hit by a bug that is related to the URLs and considering them a canonical URL. It seems that Google has replaced one URL with many other URLs for many websites.
This is the reason why you see huge fluctuations in the search results and tracking tools. Many people have a thought that this could be another update and their website has been hit as URLs are once ranked, they were not ranking.

Heads-up: You may have heard some rumblings about indexing issues and canonical problems over the past few days. I had a news publisher reach out to me that has seen 1,300 articles get canonicalized TO COMPLETELY DIFFERENT ARTICLES. Here is the top article for the site, nuked: pic.twitter.com/Ry9jSFSfz0
