Hi,
I see that you are concerned about the 404 error on your website.
It is wise to check the 404 report from Google Search Console.
But the 404 report of Google Search Console sometimes lags behind and appears in the report much later than the 404 error that appeared earlier, because it has limited crawling resources for each website, so it often lags behind.
But if your website has a 404 error, it may be indexed and appear in Google search results. Users may click on your website’s 404 error, which will confuse users and you may lose a click traffic.
So I suggest you use the redirect shopify app, because it can set users to automatically redirect to other normal pages of your website after clicking on 404.
