As I was late to notice, I created a new site in the root directory, copied all pages in the subdirectory, and applied for Google Adsense.
It is good for the examination to pass, but it took extra time.
Summary
The Google Adsense screening target seems to be all pages under the unique domain.
So it seems that even if I create a blog in a sub-directory like me, I could receive a review.
Attention 1
It is necessary to create a blog in the root directory and put an entrance to the blog on the top page.
Therefore, you need to create a page with a new page.
Very easy.
I think maybe it is good to put only one post and put the URL of the blog, but I think it is better to make a fixed page and set it as the top page.
Entrance to the blog
URL (https ~)
Just make a fixed page like this and set it in dashboard → appearance → customization → homepage setting, so it takes only 1 minute.
Attention 2
It seems that the page being made is also subject to the examination.
If there is inappropriate content on the page you are creating, it will be disqualified.
Therefore, it is not a good idea because it is not published.
Supplement
I wrote the title that you can apply in the subdirectory, but it is assumed that you have acquired your own domain.
This is information for people who want to run several sites and want to lighten the root directory (don’t want to create a site in the root directory).
Therefore, it does not mean that you can apply for Google Adsense via a free blog.
This is a free blog subdirectory ↓
https://ameblo.jp/***/
ameblo.jp has its own domain. You have to get this.
Of course, in this example, the cyber agent of Ameba’s operating company has acquired its own domain of ameblo.jp.
Comments
If i have domain like domain.com and want to make new subdirectory: good.
when new subdirectory site submit to adsense. Link will look like this domain.com/good am i right?
Please apply for Google Adsense in the main directory.
Google Adsense examines everything in the main directory.
Of course, Google Adsense also examines domain.com/good.
As a precaution, you should paste the URL of the subdirectory on the top page of the main directory.
