Virtuemart: Category tittle in google search

[psm]

Dear all, I have problem with google search.

I use joomla 3.8.11, Virtuemart 3.4.2 and when I check my page title on my site it is in this form:

[category tittle]: [product name] | [Site name]

and it is similar in google search results. But bigger problem is that some of products are not showed in google search result or there is just category name.

Can you please advice me how to fix it and set up page title as: [product name] | [Site name]?

Thank you very much

Do you tried to add the custom title when you fill your product admin side ?
