Who should own my Google Ads account, me or the agency?
You should. Your business should own the Google Ads account, the billing, Google Analytics and the conversion tracking from day one, and the agency should work in it through access you grant. If you leave, you keep every keyword, ad, search term and year of data.
Agencies normally link your account to their manager account, which lets them work in it without owning it. You can remove that link whenever you like.
If an agency builds the account under its own login, ask for ownership in writing before any spend starts. Moving later is possible but messy, and some agencies make it slow on purpose.
The same rule applies to everything around the ads: your website, Google Business Profile, Tag Manager and call tracking numbers. At Scalepoint, you own every account from day one.
