Hi. Suddenly all my pages are not indexed, whats up?

Hello! A few weeks ago, our shop was functioning well with occasional sales, and Google search console showed no major issues. However, upon checking recently, 99% of our pages are no longer indexed. I had submitted a sitemap before, but now this situation is frustrating. The main issue is that they are not canonical, along with other problems. What steps can I take to resolve this?

You should check the “Manual Actions” section of Google Search Console to see if there are any penalties or issues affecting your site’s indexing. If you’ve been penalized, there should be an error reported specifically for the de-indexed pages. Providing this error information can help determine the cause of the indexing issue.
