index images by default

Hello,

Thank you for contacting the support.

First question
Is it neseccsary the images to be index?

It completely depends on you whether you want to get the images indexed or not.

Second question
If it is, is ti possible to be by deafult indexed all images?

Assuming you’ve set the products indexable, we provide an option under the robots meta, where you can select if you want to get the images of the current post/page/CPT indexed.

Here’s a guide regarding it:

You can also set the default global settings from Rank Math > Titles & Meta > Posts/Pages/CPTs > Robots Meta. Here’s a screenshot: https://i.rankmath.com/SLc8lG

Hope this helps.

Thank you.
