Avoid reprocessing images already handled by earlier ALT SEO tasks.
Enable Skip previously processed when re-running bulk work so images already handled by ALT SEO are not charged again.
Combine with overwrite
- Skip on + overwrite off — fill gaps without touching prior ALT SEO work
- Skip off + overwrite on — force a fresh pass on the full selection
If you expect images to be skipped and they were, check History for counts and status.
