What URL will Googlebot crawl when you use the meta fragment tag with a regular hash URL?

Question

my client wants to use AJAX crawling (I know that it is deprecated But he wants it to use because of another search engine that still support it such as yandex.ru)

So I have URL like this:

http://example.com/#/card/card_slug?category=car

I feel it pretty ugly to transform it to this:

http://example.com/#!/card/card_slug?category=car

So I decided to use <meta name="fragment" content="!">

What page will Googlebot look for when he goes to this page:

http://example.com/#/card/card_slug?category=car

(like example.com?category=car&_escaped_fragment_=#/card/card_slug)

Answer 1

http://example.com/#!/card/card_slug?category=car

fetched as following and indexed.

http://example.com/?_escaped_fragment_=/card/card_slug%3Fcategory%3Dcar

single # url's are not crawled /i'm not sure/ and definitely not indexed

Answer 2

Use the above link to fetch your URL in search console and Google will likely tell you what page it fetched with your # parameter in the URL.

I think the most likely result is that it will ignore everything after the # and only fetch example.com, but I am not sure.
