Question About Label Limits

[Dorian Kind]

Hey there,

on the limits page of the API documentation there's a section about "Labels" (https://developers.google.com/adwords/api/docs/appendix/limits#label). From the description of the two limits, I would assume they are specific to AccountLabels (even though the links in the "Error" column send you to the LabelService and not the AccountLabelService).

Seeing as there is no other mention of Labels on the page, I wonder what the actual limits for non-account labels are, especially whether there is a maximum number of entities (campaigns, ad groups etc.) to which you can link a single label.

Thanks for any feedback and best regards,
Dorian

Hello Dorian,

This is a great question. I'm not sure of the specific limits, so I'm going to do a little research to find out, and I will update the documentation to show my findings. I'll let you know as soon as I have an answer.

Hello,

I have updated the documentation on limits to address the parts that were missing before. Please see the updated documentation and let me know if you still have any questions.

Hi Mike,

many thanks for your quick response and the documentation update. I'm not sure if I understand the "Maximum number of labels that can be applied to entities [...] within an account" correctly.

Does this mean that you can have up to 100'000 *different* labels within an account?

If so, can you confirm that there is no limit on the number of "applied labels" apart from the fact that each entity can have a maximum of 50 labels applied—so only accounting for the dominant limit of 5 million criteria per Adwords account, that would theoretically sum up to 250 million applied labels?

I am asking because we have accounts where over 100'000 adgroups have labels applied (though only about 10 different labels).

Thanks again and best regards,

Dorian

Hello,

That is correct. You can have 100,000 total different labels, but a given label can apply to any number of entities.
