Google Ads Explained: How Paid Search Advertising Works
You've probably seen businesses appear at the top of Google with a small “Sponsored” label.
Those are Google Ads.
Google Ads allows businesses to pay to advertise across Google's network, including on Google Search.
But how does it actually work?
Someone searches for something
Imagine someone in Oslo searches:
“Emergency plumber Oslo”
A business that offers emergency plumbing services may want to appear when that search happens.
With Google Ads, businesses can create ads that are eligible to appear for relevant searches.
The advertiser typically chooses keywords, sets campaign targeting and determines how much they are willing to spend.
You don't simply pay to be #1
A common misconception is that the business willing to pay the most automatically gets the top position.
That's not how Google's ad auction works.
When a search takes place, Google uses an ad auction to determine which eligible ads appear and in what order.
The auction considers factors including the advertiser's bid and the quality and relevance of the ad and landing page.
This means the highest bid doesn't automatically guarantee the top position.
You usually pay when someone clicks
For many Search campaigns, advertisers use cost-per-click (CPC) bidding.
That means the advertiser pays when someone clicks the ad rather than simply because the ad was shown.
How much a click costs can vary significantly depending on the search, competition and other factors.
Keywords connect searches with ads
Keywords help advertisers tell Google which searches may be relevant to their advertisements.
For example, a local electrician might target searches related to:
Electrician Oslo
Electrician near me
Emergency electrician
Electrical installation
However, advertisers don't simply control exactly which searches trigger an ad by typing in a few keywords.
Google considers the meaning and context of searches when determining whether an ad is eligible to enter the auction.
That's why proper campaign setup matters.
Your landing page matters too
Getting someone to click your ad is only the beginning.
The person then needs to arrive somewhere useful.
If your ad says:
“Emergency Plumber in Oslo”
but the landing page doesn't clearly explain the emergency plumbing service, the customer may leave without contacting you.
A good campaign therefore needs more than an attractive advertisement.
Your:
Search → Ad → Landing Page → Offer → Contact/Purchase
should make sense as one journey.
Google Ads can provide immediate visibility
One reason businesses use Google Ads is that ads can provide visibility without waiting for organic search rankings to develop.
However, paid advertising and SEO are fundamentally different.
With Google Ads, you pay for advertising.
With organic search, you're competing for unpaid visibility.
Google Ads can therefore be useful when a business wants to actively advertise specific services or reach people searching for them.
Advertising still requires measurement
Getting clicks isn't necessarily the goal.
What matters is what happens after the click.
Depending on the business, you may want to measure:
Phone calls
Contact form submissions
Bookings
Purchases
Leads
Cost per conversion
For example, a campaign that receives 100 clicks but produces no customers may need a completely different approach from one that produces 10 clicks and several qualified leads.
Is Google Ads right for your business?
It depends on your customers, services, competition, budget and goals.
Google Ads can be particularly relevant when potential customers actively search for the type of service you provide.
But advertising should be evaluated based on business outcomes—not simply impressions or clicks.
