of ChatGPT ad headlines were net new rather than reused from other channels
- Reader Note:
- From Graphite's headline analysis rather than the Similarweb panel. “Net new” means the copy is specialized to ChatGPT instead of being reused from other channels, as described in the report summary. The source does not spell out the exact matching method used to decide whether a headline was new.
