Many clients will run ad accounts in multiple languages so it's important to be able to translate queries into a language the individual managing the account can understand. You can can do this relatively easily for the Add Queries tool.
When using Google Chrome, you can just right-click on the add queries tool page and select "translate to English".
This will update all queries on the page and the "matching kws" column to English, so you can quickly see which queries are relevant to be added and if the ad group we're suggesting adding the query to is the best place!
When you add the queries as keywords or negatives via the "exact" or "negative" buttons in Squared, they will be added in Google Ads in their original form/language.
N.B. to translate the webpage back to the original language, follow the same process and select "detected language" in the top right.
