There is a maximum limit of
1000 keywords per campaign in order to ensure efficient report generation and convenient viewing.
Adding more than 1000 keywords to a campaign will cause some functionality to be disabled.
If you need to track more than 1000 keywords for a site, then best practice is to create additional campaigns (e.g., separate them by keyword category, location, tags, etc.). If you have an Enterprise package, you can view rank performance data for multiple campaigns in the
Portfolio Report and by using cross-campaign metrics in the
Insight Graph and
Single Metric Widgets.
