The Absolute Beginners Guide to Google Ads
Apr 16, 2025If you’re looking to run your first Google Ads campaign in 2025, this guide is your essential starting point.
Google has made it easier than ever to set up campaigns. But without understanding the core concepts of how Google Ads works, you risk wasting money and missing your target audience. In this beginner-friendly guide, we’ll break down everything you need to know to create a successful, cost-effective Google Ads campaign.
Google Ads Is an Auction—But Not the Kind You Think
Many beginners assume that Google Ads works like eBay—the highest bidder wins. But that’s a common misconception.
Google Ads operates on an ad auction system, but it doesn’t simply reward the highest bid. Instead, Google uses something called Ad Rank to determine which ads appear and in what order.
How Does Google Decide Which Ads to Show?
Every time someone performs a search, Google runs a real-time auction. Your ad’s placement depends on your Ad Rank, which includes:
-
Your bid (the maximum you’re willing to pay per click)
-
The quality and relevance of your ad
-
The context of the searcher (location, device, time of day)
-
The expected performance of ad extensions and assets
-
Whether your ad meets minimum quality thresholds
Higher quality ads and better user experiences lead to better results—even with lower bids.
What Influences Your Ad Rank?
Your Ad Rank determines your ad position on the results page. These are the key factors:
-
Bid amount – How much you’re willing to pay for each click
-
Ad quality – Includes expected click-through rate (CTR), relevance, and landing page experience
-
Ad Rank thresholds – The minimum quality needed to be shown
-
Competition – The strength of other ads in the same auction
-
User context – Location, device type, time, and search history
-
Ad extensions and formats – Enhancements like sitelinks or callouts
For example, if you bid $2 and have a 12% CTR, while your competitor bids $5 with a 3% CTR, you win. Google rewards relevance and user value over pure budget.
Key takeaway: You don’t need the biggest budget. You need well-optimized, relevant ads that meet users’ needs.
Where Do Google Ads Appear?
When setting up a campaign, it's important to understand where your ads can be displayed. Google Ads allows your ad to show across multiple networks:
-
Google Search results
-
Google Shopping listings
-
YouTube video ads
-
Gmail promotions tab
-
Mobile app placements
-
Google Display Network (ads across millions of websites)
Each of these placements falls under a different Google Ads campaign type. Choosing the right one ensures you attract the right kind of traffic and maximize your ad spend.
Google Ads Targeting: Reaching the Right Audience
One of the most powerful features of Google Ads is its precise targeting. You can fine-tune your campaign to reach ideal customers based on:
-
Keywords – What they’re actively searching for
-
Geographic location – From country-level to city or even a specific radius
-
Device type – Desktop, mobile, or tablet
-
Audience signals – Behaviors, interests, demographics, and past interactions
With smart targeting, your ad appears exactly when your potential customer is searching for your product or service.
Understanding Google Ads Structure: The 3 Campaign Levels
To manage your campaigns effectively, you need to understand the Google Ads account structure, which has three levels:
-
Campaign – Where you set your daily budget, location targeting, and network
-
Ad Group – Where you group related ads and keywords by theme
-
Ads and Keywords – Your creative assets and the actual search terms you want to target
Think of it like a tree:
Campaigns are the trunk, ad groups are the branches, and individual ads are the leaves.
A clear structure allows for easier optimization and better control over your performance.
Key Google Ads Metrics to Track
Once your ads are live, tracking the right metrics is essential for success. Focus on these performance indicators:
-
CTR (Click-Through Rate): Measures the percentage of users who clicked your ad
-
CPC (Cost Per Click): The average amount you’re paying per click
-
Conversion Value / Cost (ROAS): Measures your return on ad spend
-
Search Impression Share: Shows how often your ad appeared compared to how often it could have shown
By monitoring these metrics, you’ll understand which parts of your campaign are working—and which need improvement.
