1. Introduction to Google Ads

Google Ads, formerly known as Google AdWords, is Google’s advertising platform that allows businesses to display ads on Google’s search engine results page (SERP), YouTube, Gmail, and across millions of websites in the Google Display Network. Google Ads is a pay-per-click (PPC) model, meaning advertisers pay only when someone clicks on their ad.

Why is Google Ads Relevant in 2025?

• • Over 90% of online experiences begin with a search engine, and Google owns over 92% of that search market share.

• • The average return on investment (ROI) for Google Ads is $2 for every $1 spent, and even higher for optimized campaigns.

• • With the rise of voice search, AI-powered ad optimization, and mobile-first browsing, Google Ads is more powerful than ever.

2. How Google Ads Works

At its core, Google Ads operates on a bidding system where advertisers bid on keywords relevant to their product or service. When a user enters a query, Google runs an auction to determine which ads will show, in which order, and at what cost.

The Auction Process:

• • Advertisers bid on keywords.

• • Google evaluates:
    
    • • Ad Rank (based on bid + Quality Score)
    • • Quality Score (CTR, relevance, landing page experience)

• • The highest-ranking ads are displayed to users.

This means success doesn’t rely solely on the biggest budget—it rewards advertisers who create relevant, well-optimized campaigns.

Even though Google Ads is powerful, it can quickly become a money drain if not executed properly.
