How Google Ads Works (Explained for Beginners)

At its core, Google Ads is a massive real-time auction system.

When a user searches a keyword, Google instantly decides which ads to show and in which order.

Here's the simplified flow:

2.1 The 3 Core Elements That Decide Your Ad Results

① Keywords

You bid on keywords such as:

• “buy iPhone case”

• “hotel in Bangkok”

• “B2B software demo”

• “Google agency account”

Keywords reflect and match the user’s intent.

② Auction Bidding

Google uses a pay-per-click model (PPC) —You only pay when someone clicks your ad.

In 2025, most bidding uses Smart Bidding powered by AI:

• Maximize Conversions

• Maximize Conversion Value

• Target CPA

• Target ROAS

AI bidding became so dominant in 2025 that over 82% of all campaigns use it (Google Partner Insights 2025).

③ Quality Score + Ad Rank

Even if you bid high, Google won't show your ad unless it's high quality.

Ad Rank = Bid × Quality Score × Ad Format Impact

Google determines ad position using Ad Rank, a composite score based on:

- Your bid

- Ad relevance and quality (including expected CTR and landing page experience)

- Search context (device, location, time, other ads)

- Ad format and extensions

While “Quality Score” is no longer visible in most campaign types (eg: Performance Max), its underlying components still heavily impact cost and ranking.

What Types of Google Ads Should Beginners Start With?

Google Ads offers many formats, but beginners should start with the 3 easiest and highest-ROI types:

3.1 Search Ads — Best for high-intent buyers

Search ads convert 2–5x higher than display ads because users already have purchase intent.

Average CPC in 2025 by industry (global):

• Finance: $5.40

• SaaS: $4.18

• Ecommerce: $1.75

• Travel: $2.20

3.2 Performance Max — Google's AI-driven “all-in-one” campaign

PMax distributes ads across:

• Search

• YouTube

• Display

• Discover

• Maps

• Gmail

2025 performance benchmark:

• Global average CPA dropped 18% with Performance Max vs legacy Smart Shopping campaigns.

• ROAS increased 12–29% depending on industry.

PMAX is extremely beginner-friendly because Google does most of the optimization for you.

3.3 YouTube Ads — Low-cost branding + conversions

YouTube CPMs remain very affordable:

• Global CPM average 2025: $4.92

• Average view rate: 32%

If you want awareness + low-cost traffic, YouTube is the best channel.

Many beginners ask:

“Do I need a large budget?” No — but your cost depends on:

• Industry

• Keyword competitiveness

• Bidding strategy

• Quality Score

Step-by-Step: How to Set Up Your First Google Ads Campaign

Step 1 — Define your goal

Choose:

• Sales

• Leads

• Website traffic

• Brand awareness

Your goal affects bidding, placements, and optimization.

Step 2 — Do Keyword Research

Use tools:

• Google Keyword Planner

• Ahrefs

• SEMrush

Tip: beginners should choose a mix of:

• Broad keywords for reach

• Phrase match for control

• Exact match for ROI

Step 3 — Create a High-Quality Landing Page

Google evaluates your page's:

• Load speed

• Relevance

• User experience

• Conversion friendliness

A good landing page can increase Quality Score and lower CPC by 30–50%.

Step 4 — Write Compelling Ads

Formula for high-CTR search ads:

• Include the keyword in the headline

• Use strong value propositions

• Add emotional triggers

• Include a CTA

Example:“Get a Google Agency Ad Account — Fast Approval | Novabeyond”

Step 5 — Launch with Smart Bidding

Beginners should use:

• Maximize Conversions (no CPA target in the first 7–14 days)

• After stability → switch to Target CPA or Target ROAS

Google's AI needs time to learn — this is called the Learning Phase.

Step 6 — Add Negative Keywords

This avoids wasteful clicks.

Example negative keywords:

• free

• tutorial

• jobs

• definition

Campaigns with negative keywords save 15–27% of the budget.

Step 7 — Optimize Weekly (not daily)

Google recommends:

• Adjust budgets weekly

• Review search terms

• Improve landing pages

• Refresh creative monthly

• Add more data signals (for PMAX)

2025 Google Ads Algorithm Changes Beginners Must Know

In 2025, Google made major updates:

① AI First Optimization

AI controls:

• Bidding

• Creative combinations

• Placement decisions

Advertisers with mature accounts typically those managed by experienced agencies saw 21–38% better performance, largely due to:

• Richer conversion data

• Better-structured campaigns

• Faster policy compliance

New advertisers can accelerate this by using optimized account setups (eg: via vetted partners).

② Privacy Sandbox

Third-party cookies are gone.

Google now uses:

• Topics API
