How to check image indexing?

Question

Search engines

Hello! I recently noticed that the pictures from my site (unique) are not visible in google (right-click on the picture -> find the image in google), even those that were added more than six months ago and the pages on which the pictures are perfectly indexed. The site is a year old, has 3k pages in the index, started indexing 9 months ago
, while a competitor (whose site was not completed, was created half a year ago) searches for each picture in this way even in those articles that were added less than a month ago.
In which direction to dig?
An example of a page with unique photos: mirpovara.ru/recept/1093-salat-iz-krabovyh-paloche...

Answer 1

Yes, there seem to be pictures, like this, googled "site: mirpovara.ru " in the pictures section
PS and those in the index are searched through a search by picture
