Number at SEO meta-data (website settings)

Is the number here at SEO meta data Pixels?
How do you guys create these information?
Do you use any tool like SERP Snippet Generator
Is the slogan shown somewhere?

In this example title and description has been “green” meaning OK before I typed in the slogan.


Hi @Barbara_Bichler, the number is the total character length of the field. Each character has a different length. e.g. is “O” wider than “i”. The total character length is important, because if the text is too long (total character length), it will not fully display in the search results.
