This article explains how Google Ads works, its types, benefits, bidding system, campaign process, and tips to achieve better results.

What is Google Ads?

Google Ads is an online advertising platform developed by Google where advertisers pay to show their ads on Google Search, YouTube, websites, mobile apps, and more.

It works on a Pay-Per-Click (PPC) model, which means advertisers only pay when someone clicks on their ad.

For example:

• A user searches for “Digital Marketing Course in Pune.”
• Google shows relevant ads at the top of search results
• When the user clicks the ad, the advertiser pays a small amount

Google Ads helps businesses target customers exactly when they are searching for products or services.
