Ok, so I just have to wait for Google to remove them, do you know how long that could take?

Hi, I didn't do redirects, the Shopify website was only open for a few days, do I need to do redirects? I added a WordPress sitemap to Google Search Console a few weeks ago

It takes time Google to detect the changes.Do you have made the redirects to all those old pages and submit the new website pages to search CONSOLE?do THAT FIRST.

Hi, hello everyone, a while ago I built a website on Shopify, a few days after I built it I decided to move to WordPress, so I transferred all the products there and after a while I closed Shopify, at the moment I have many pages that were from Shopify that appear on Google and when I click on them I see A blank page on my site, it's been a few weeks since I deleted the site on Shopify but they still show up in google search, what am I supposed to do with all these pages?
