AdWords: Close variant matching for all exact and phrase keywords

As previously announced on the AdWords blog, we're improving how exact and phrase keywords match to users' search terms. Starting in late September, all phrase and exact match keywords will begin matching close variants, including misspellings, singular/plural forms, stemmings, accents, acronyms and abbreviations.

Specifically to the API, this means the following:
  • The next API version will no longer accept KeywordMatchSetting for campaigns.
  • Existing API versions will ignore the value sent for the optIn field of KeywordMatchSetting.
  • Regardless of the optIn field value, all exact and phrase match keywords will match close variants.
Close variant matching is already enabled by default for new campaigns, so if you haven't specifically set the optIn field, you won't see any changes in keyword matching behavior.

If you have any questions, please feel free to contact us on the forum or via the Google Plus page.
