Step 2: Submit Business Information. Provide business information, including business papers, advertising website, and budget.
Step 3: Account Creation.
On the Google Ads page, click the blue "Start now" button in the upper right corner. Select the email you want to register under. If you already have a Google Account (Gmail), use this email address.
