Hi,
Mostly its the blog articles with /amp or /?amp pages in them. Here’s the screenshot https://ibb.co/7zCw5mr
Hello,
I’ve checked the /amp/ URLs, and they are already redirecting to the actual posts. For /?amp, there’s no need for redirection since the query parameter will be ignored, and the browser will load the canonical non-amp page for your visitor.
In this case, please revalidate the issue in your Google Search Console account and give Google some time to recrawl your site.

Hope that helps.
Thank you.
Hi Reinelle, Yes that’s what I am doing.
Btw, how can I redirect old custom post type to new one?
Our old one is /marketing and I wanted to redirect all of the post to /agency
can you please help? Thanks!
Hello,
Please follow these regex redirect formats for such redirections:
1. Redirect all posts from /marketing to /agency only:
Source URL: marketing/(.*)
Destination URL: https://yourdomain.com/agency/
2. Redirect all posts to /agency/ and copy the same slug/URL:
Source URL: marketing/(.*)
Destination URL: https://yourdomain.com/agency/$1
Hope that helps.
Thank you.
