The updated Keyword tool for AdWords is to come out of beta testing and replace the existing Keyword tool and Search-based keyword tool by the end of the month.

Announced last year, the updated keyword tool is Google’s attempt at realising its “long-term goal” of combining the features of the existing tools into one comprehensive feature. Following a year of beta testing, the company has announced on its Adwords Agency and Inside AdWords blogs that it is about to make the final transition to the new feature.

After the end of August, both existing tools will have their web addresses redirect to the new updated Keyword Tool, says Dan Friedman of Google. When that happens the updated Keyword tool will come out of beta – dropping the “updated” section of its name.

The new tool offers “flexible search options”, allowing advertisers to search by any combination of keywords, website/URL or category information and receive a single set of comprehensive results. It allows for easier keyword refinement, allowing users to filter by word or keyword match type, as well as a range of advanced options such as statistics for mobile search or data filters for local searches and ad share.

These features already existed in the two separate tools but will now be accessible from the same interface. Additionally, two new features apparently generated by feedback from the beta have been added – the ability to remove duplicate keywords through the addition of a simple notification when accessing the keyword tool within an ad group (“Already in ad group”) and “adding negative keywords.”

“We’ll continue to improve upon the updated keyword tool to make it more useful for you,” says Friedman.
