I have two websites which are twin, both using
schema.org microdata format to construct structured data.
Both websites had their data visible in google webmaster console. But i noticed a sudden drop in one of the website's statistics. Here is an screenshot:
As you can see there is a huge drop in the number of identified markups. I didn't modify the HTML files or remove anything, i was actually posting more contents these days. However, everything is fine in the twin website.
Here is an screenshot from the twin's search console:
As you can see the numbers are growing each day, even when the twin has less posts and hasn't been updated in months.
What's happening here? I've checked my HTML markups and i can still see the structure is intact.
PS I have to mention the twin website is in Russian, while this site is in English, so i don't think it would be a matter of duplicated content.
