1. What is Google Ads?

Google Ads, formerly known as Google AdWords, is an online advertising platform developed by Google, where advertisers bid to display brief advertisements, service offerings, product listings, or videos to web users. These ads appear across Google Search, YouTube, websites in the Google Display Network, and more.

Essentially, it allows businesses to reach potential customers exactly when they are searching for products or services related to what you offer.


2. How Does Google Ads Work?

At its core, Google Ads functions on a Pay-Per-Click (PPC) model. This means you only pay when someone clicks on your ad. Here’s a simplified explanation of how it works:

Step-by-Step Process:

  1. User Search: A user types a query into Google (e.g., “best digital marketing course”).
  2. Ad Auction: Google checks its pool of advertisers to see who is bidding on keywords related to the user’s query.
  3. Ad Rank: Google uses multiple factors—like bid amount, ad quality, and relevance—to determine which ads appear and in what order.
  4. Ad Display: The top ads are shown on the Search Engine Results Page (SERP).
  5. Click & Payment: If a user clicks your ad, you are charged based on your bid.

3. Types of Google Ads Campaigns

Google Ads offers several campaign types, depending on your marketing goals.

1. Search Ads

Text ads that appear on the Google search results page when users search for a product or service.

2. Display Ads

Image or banner ads that appear across millions of websites in the Google Display Network (GDN).

3. Shopping Ads

Product-based ads with images and prices, perfect for e-commerce businesses.

4. Video Ads

Ads shown on YouTube, either before, during, or after videos.

5. App Campaigns

Designed to promote your app across Google Play, Search, YouTube, and the Display Network.

6. Performance Max

An AI-powered campaign type that uses automation to show ads across all Google properties.


4. Benefits of Using Google Ads
