I manage a blog. Do I need to validate each blog post link individually?

[ACLU]

We’ve set up our CMS to pull metadata from the title, image, etc by default. We’ve validated a handful of links, but would like it if these cards appeared automatically.

Do we need to validate each link individually? Or can we get whitelisted so all of our blog links have cards?

Here is our blog: https://www.aclu.org/blog

Here are some links that I have validated:

You need to validate and request approval only once for each card type you are using on a domain. So if you are using 2 different cards type, you need to validate and request approval for 2 pages, each one with a different card type.
In fact if the domain already has been approved for a card type, the validator will tell you.

Thank you. We’ll take another look at the meta data, validate, and let you know what happens!
