Going over the allotted keyword limit can incur keyword overages. Refer to your contract to determine your keyword limit.
Here are some useful tips to help avoid keyword overages:
- Unfollow Irrelative Keywords - Keywords relativity change over time. Perhaps you added keywords that were campaign specific, old product lines or locations you no longer service. Unfollow these keywords to free up space.
- Unfollow Irrelative Search Engines - Similar to keywords sometimes Search Engines become irrelative. This could be because of market share, locations or marketing direction.
- Review your Actual Usage - When making changes to your keywords within your account be sure to review the Actual usage to know how many keywords you have removed.
