Dynamically Inserted Titles

What is the character limit of the backup title?

[positionleap]

Does anyone know the character limit for the backup text for dynamically inserted keywords?
Ie.

{KeyWord:Blue Widget Kingdom}

When their search length exceeds a certain number of characters, the text "Blue Widget Kingdom" will display. What is the character limit for the backup text?

I read in another thread its 15 characters, but that was posted 2 years ago.

Essentially the limit depends on the number of other characters in the line outside the braces and which line you are using it in. For e.g if you are using it in the Ad Title line. The total limit is 25 characters and let's say your ad title says "{KeyWord:Default Word} Info". The number of characters outside the braces is 5(Space plus 'Info'). So Default Word can take up to 20 words now.
