Compare Lists Tool
Analyse two lists of search terms (or any text items) to identify overlaps, differences and unique elements.
When you enter two lists, the tool automatically compares them and generates structured outputs, giving you a clear overview of how your lists relate to each other.
What it generates
- Unique in List 1: terms that only appear in the first list.
- Unique in List 2: terms that only appear in the second list.
- In Both Lists: the intersection, terms appearing in both lists.
- All Unique Items: merges both lists and removes duplicates.
- All Items (Deduplicated): a complete combined list without repeated values.

When to use it
The Compare Lists Tool is ideal for cleaning up keyword lists before uploading into ad platforms, comparing historic vs. new search terms, understanding overlaps between campaigns or ad groups, preparing negative keyword structures and auditing client keyword lists. It's a simple but powerful utility to keep your search structures clean and efficient.
