Plz guide me. Why? my website is not showing "cache option" in search result. when I check Ex- (Cache: http://example.com ) then it shows - "404. That’s an error." URLs are indexed & no any issues in search console. We dropped my ranking due to it. so plz

Answer 1

Google does not have a cached copy of the url (not website).

Google takes a snapshot of the url as of when Google last crawled it (source).

Not having one means either:

1. there is no cached version of the url; or
2. there is only one cached version (the current one) so a drop down is redundant.

Keep in mind that while you may have made various changes to the url, that does not mean that Google has cached all the changes - typical with 'younger' sites.

Hope that helps.
