A new update on this issue. By all means please see the screenshot below:
I have perform a fetch on every single pages that I have told as being excluded before (if you ever do this, it is a chore indeed, but I did it anyway for the sake of proving an issue here).
And the result is? A new category is made up in Google Search Console as "Duplicate, submitted URL not selected as canonical". Most of the fetch (if not all) I did, are clumped inside this category. Basically they are still being excluded, just changing category. NICE! VERY NICE!
You can see the last crawled date in the screenshot above, which I underlined in red mark, is very new. And as I said before when I clicked the view as search result, most of them were pointing to the main blog feed page, not the actual blog.
6 days ago, I published a new blog post and it is directly being excluded and regarded as "Discovered - currently not indexed". See the one I circled around in the screenshot below, that is the newest blog post.
From the first time I faced this issue, I always believe it is due to the messy SEO structure of the New Wix Blog. And that is still the case now.
Based on the response so far I feel that this thing isn't being considered as an issue at all. Or if it is, then it is being considered as unimportant one. But seriously pages being excluded from Google search is unimportant?
