Formats and limits

Each format produces a fixed set of parts, one per field the destination platform asks for. Every part has a recommended maximum length; the generator writes within it and flags anything longer so you can trim before publishing. A single run can include up to 4 formats, and each format counts as one generation.

About the limits

Limits follow each platform's published recommendations at the time of writing (for example 30-character headlines and 90-character descriptions for Google responsive search ads). Platforms change their rules; when they do, the limit is updated here and in the generator at the same time.
