Hi Anna GG,
Thank you for using our Microsoft Advertising Community Forum! My name is John, and I will be assisting you with this query.
I'll provide one of the options that you can utilize using the Microsoft Advertising Editor.
Once you open your account on the Microsoft Advertising Editor look for keywords and targeting from the bottom left part then expand it.
Select companies
Add company to target then select the campaign(s) or adgroup(s) that you would like to associate from the targeting
You can search and select multiple companies (Up to 1000) from the small checkbox on the left. You can also export these lists of companies to get the profile ID (Used for making multiple changes, if you have your own list of specific companies)
Post your changes once you finalize the company targets. Make sure to double check everything before clicking “Post” as this will apply all the changes that you did from the Microsoft Advertising Editor to your live account.
Note: If you already have a list of companies, you can use the multiple changes instead.
For the detailed instructions, kindly respond to my private message for further assistance.
