Have you ever searched something on Google and noticed the first few results labeled as “Sponsored”? Those are not random. They are Google Ads at work.
Google Ads is one of the most powerful online advertising platforms in the world. But if you are just starting out, you might be asking: How does Google Ads work?
In this beginner’s guide for 2025, we will walk you through everything step by step. By the end, you will know exactly how Google Ads works, why businesses use it, and how you can start running your own campaigns.
What is Google Ads?
Google Ads is Google’s advertising platform that allows businesses to show their ads on Google Search, YouTube, Gmail, and millions of partner websites.
Instead of waiting for customers to find you, Google Ads lets you reach them exactly when they are searching for products or services like yours.
For example:
- If you run a bakery in Delhi and someone searches “best bakery near me”, your ad can appear at the very top.
- If you sell online courses, your ad can show up to people searching “learn digital marketing online”.
That is the power of Google Ads.

How Does Google Ads Work in 2025?
Google Ads works on a system called Pay-Per-Click (PPC). This means you only pay when someone clicks on your ad.
Here’s the simple process:
- Choose your goal
Do you want more website visits, more phone calls, or more sales? You set the goal first. - Select your audience
Decide who should see your ads. This can be based on location, age, interests, or what they are searching. - Pick your keywords
Keywords are the search terms people type into Google. If you bid on “digital marketing agency,” your ad can appear when someone searches for it. - Create your ad
Write a short headline, description, and add a link to your website. - Set your budget
You decide how much you want to spend per day or per month. Google will never exceed your budget. - Google Ads Auction
When someone searches, Google runs a quick auction. The ads with the best bid + quality get shown at the top. - Results
If someone clicks your ad, you pay a small fee, and they land on your website or landing page.
The Google Ads Auction Explained
This is the heart of how Google Ads works. Every time someone searches on Google, an auction happens in milliseconds.
The winner is not always the highest bidder. Google also checks ad quality. This includes:
- Relevance of your ad to the search
- Landing page experience (your website should load fast and be useful)
- Expected click-through rate (CTR)
So, even small businesses with lower budgets can compete if they make relevant, high-quality ads.
Types of Google Ads Campaigns (2025)
Google Ads is not limited to just search ads. In 2025, there are multiple campaign types you can use:
- Search Ads
Text ads that show up on Google search results. Best for direct leads and sales. - Display Ads
Image or banner ads that appear on websites, apps, and Gmail. Best for awareness. - YouTube Ads
Video ads that run before, during, or after YouTube videos. Great for branding. - Shopping Ads
Product-based ads that show prices and images in Google Shopping. Best for eCommerce. - Performance Max Campaigns
AI-powered campaigns that run across Search, Display, YouTube, Maps, and Gmail with a single campaign.
Google Ads has grown a lot. Here are the main types of campaigns. If you want a detailed breakdown with examples, check out our full guide on Types of Google Ads.
Why Do Businesses Use Google Ads?
Google Ads is popular because it delivers fast results compared to SEO (which can take months).
Benefits include:
- Appear at the top of search instantly
- Target the right customers at the right time
- Control your daily budget
- Measure everything with real-time reports
- Compete even with big brands if your ads are relevant
For small businesses in 2025, this is a big opportunity to grow without spending lakhs on traditional marketing.
How Much Does Google Ads Cost?
One of the most common questions is: How much will I spend on Google Ads?
The truth is, there is no fixed price. Google Ads is flexible. You decide your budget.
- Some businesses spend ₹500 per day
- Some spend ₹50,000 per day
It depends on your goals, industry competition, and keywords.
On average in India:
- Cost per click (CPC) can range from ₹10 to ₹150 depending on the industry.
The good news is, you only pay when people click your ad. If nobody clicks, you do not pay.
Example: How Google’s Advertisement Works for a Local Business
Let’s say you own a salon in Mumbai.
- You choose your goal: More bookings
- You target women in Mumbai aged 20–40
- You select keywords: best salon in Mumbai, haircut near me
- You create an ad: “Top Salon in Mumbai – Book Your Appointment Today”
- You set a budget: ₹1,000 per day
- Your ad shows up when people search for salon in Mumbai
- Someone clicks → You pay ₹40 → Customer visits your website → Books an appointment
Simple, right?
Is Google Ads Worth It in 2025?
