Dear Community, I have the following problem and would be super helpful if you guys would be able to help. Cheers
-
Symptoms :
-
On the search console, Google says that some of our old URLs are indexed but not submitted in sitemap
-
However, those URLs are in the sitemap
-
Also the sitemap as been successfully submitted. No error message
-
Potential explanation :
-
We have an automatic cache clearing process within the company once a day. In the sitemap, we use this as last modification date. Let's imagine url www.example.com/hello was modified last time in 2017. But because the cache is cleared daily, in the sitemap we will have last modified : yesterday, even if the content of the page did not changed since 2017.
-
We have a Z after sitemap time, can it be that the bot does not understands the time format ?
-
We have in the sitemap only http URL. And our HTTPS URLs are not in the sitemap
What do you think?
