What is Google Ads?
Google Ads is Google’s paid advertising platform that allows businesses to display ads across Google’s vast network. This includes:
- Google Search Network – Ads shown on search results when users type specific queries.
- Google Display Network (GDN) – Visual banner ads shown on millions of partner websites.
- YouTube Ads – Video ads shown before, during, or after YouTube videos.
- Shopping Ads – Product-based ads shown on Google Shopping results.
- App Promotion Ads – Ads that promote app downloads across Google Play, YouTube, and search results.
At its core, Google Ads works on a Pay-Per-Click (PPC) model, meaning advertisers pay only when someone clicks their ad. This makes it highly cost-effective if campaigns are managed properly.
How Does Google Ads Work?
Google Ads works on a real-time auction system. Here’s a step-by-step breakdown:
1. User Searches for a Keyword
When someone types a search query on Google, the system checks whether advertisers are bidding on that keyword.
2. Auction Begins
Advertisers compete in an ad auction. Google considers two main factors:
- Maximum Bid (how much you’re willing to pay for a click)
- Quality Score (based on ad relevance, landing page quality, and click-through rate)
3. Ad Rank is Calculated
Google uses the formula:
Ad Rank = Maximum Bid × Quality Score
The higher the Ad Rank, the better position your ad gets on search results.
4. User Clicks the Ad
If a user clicks, you pay the actual cost per click (CPC), which is often less than your maximum bid.
Types of Google Ads Campaigns
Google Ads offers multiple campaign types depending on your business goals:
1. Search Campaigns
- Text-based ads on Google search results.
- Best for intent-driven marketing (e.g., “buy running shoes online”).

- Visual ads (images, banners) across millions of websites.
- Great for brand awareness and retargeting.
3. Video Campaigns
- Ads shown on YouTube.
- Excellent for storytelling and audience engagement.

- Perfect for e-commerce businesses.
5. App Campaigns
- Promote mobile apps across Google Play, YouTube, and partner networks.
