Step 1: Create a Google Account

Skip if you already have a Gmail or Google Workspace account.

  1. Go to https://accounts.google.com/signup
  2. Fill in: name, email (or create a new Gmail), password
  3. Verify your phone number
  4. Accept terms

Step 2: Create a Google Ads Account

Option A: Standard Account (for one business)

Google Ads - Standard Account Setup

  1. Go to https://ads.google.com

  2. Click Start now

  3. Enter your business name and website URL when prompted

  4. Google will try to walk you through creating a campaign — skip all other steps

  5. Confirm your settings:

    • Billing country: Where your business is based
    • Time zone: Your local time zone
    • Currency: Your preferred currency

    ⚠️ Billing country, time zone, and currency CANNOT be changed later. Choose carefully.

  6. Click Submit

Your account is created. You'll see your Customer ID — a 10-digit number in format XXX-XXX-XXXX — in the top right corner. Save this number.

Option B: Manager Account / MCC (for managing multiple accounts)

What is this? A Manager Account (also called MCC = My Client Center) is a "master" account that manages multiple Google Ads accounts. Use this if:

  • You're an agency managing clients' ads
  • You have multiple brands with separate ad accounts
  • You want centralized reporting across accounts

Google Ads - Manager Account Setup

  1. Go to https://ads.google.com → Click Start now

  2. At the bottom, click Are you a professional marketer? Switch to a manager account

  3. Enter:

    • Account display name: Your company name
    • Primary use: Select "Manage other people's accounts" or "Manage my accounts"
    • Billing country: Where your business is based
    • Time zone: Your local time zone
    • Currency: Your preferred currency

    ⚠️ These settings CANNOT be changed later. Choose carefully.

  4. Click Submit

Linking a client's ad account to your MCC:

  1. In your MCC → Settings → Sub-account settings
  2. Click Link existing account
  3. Enter the client's 10-digit Customer ID
  4. The client receives an email invitation → they must accept it

Step 3: Set Up Billing

Without billing, you cannot run ads.

Google Ads - Billing Settings

  1. In Google Ads, click Billing (left sidebar) → Settings
  2. Click Add Payment Method
  3. Choose:
    • Credit card / Debit card
    • Bank account (varies by country)
    • Bank transfer / Invoice (for larger accounts, varies by country)
  4. Enter payment details → Confirm
  5. Choose payment setting:
    • Automatic payments (recommended): Google charges you after your ads run, when you hit a billing threshold or at the end of the month
    • Manual payments: You add funds upfront, ads stop when funds run out

What is this? Conversion tracking lets Google Ads know when someone takes a valuable action on your website (purchase, sign-up, etc.) after clicking your ad. Without it, you can't measure ad performance or optimize campaigns.

Choose Your Tracking Method

MethodBest For
Google Tag Manager (GTM)Most businesses — manage all tags from a UI, no code changes needed
Google Tag (gtag.js)Simple sites — paste one code snippet directly on your pages

Do NOT use both at the same time. Using GTM and gtag.js together will double-count your data.

Google Tag Manager - Create Account

  1. Go to https://tagmanager.google.com
  2. Click Create Account
  3. Enter:
    • Account Name: Your company name
    • Country: Your country
    • Container name: Your website URL (e.g., www.mysite.com)
    • Target platform: Select Web
  4. Click Create → accept terms
  5. Copy the two code snippets GTM provides:
    • Paste the first snippet in the <head> of every page
    • Paste the second snippet after the opening <body> tag
  6. In GTM, click New Tag → choose Google Ads Conversion Tracking
  7. Enter your Conversion ID and Conversion Label (from Google Ads → Goals → Conversions)
  8. Set up a trigger (e.g., "Page URL contains /thank-you")
  9. Click Submit to publish

Option B: Google Tag (gtag.js)

  1. In Google Ads → Goals (left sidebar) → Conversions → Summary
  2. Click + Create button → select Website
  3. Enter your website URL
  4. Choose a conversion category (Purchase, Qualified lead, Sign-up, etc.)

Conversion Categories

  1. Google provides a Google Tag code snippet — paste it in your website's <head> tag
  2. Add the event snippet on specific pages (e.g., thank-you page)

Note: If the conversion options don't appear, you may need to create at least one campaign first. You can create a paused campaign and set it up later.

Verify Your Setup

  1. In Google Ads → Goals → Conversions
  2. Check that your conversion actions show Active status
  3. Use Google Tag Assistant (Chrome extension) to debug on your site
