Above organic

Every day, 8.5 billion searches happen on Google. When someone types “best running shoes” or “plumber near me,” they’re telling you exactly what they want. Google Ads puts your business right in front of them.

How the Google Ads Auction Works

Google Ads is not “pay more, win more.” It’s an auction where relevance matters as much as money. Every time someone searches, Google runs a lightning-fast auction to decide which ads appear and in what order.

Higher Quality Score = Lower cost per click. Google rewards relevant, useful ads.

Key insight: A small business with a Quality Score of 9 can outrank a big brand bidding 3x more — and pay less per click. Google rewards ads that genuinely help the searcher.

Quality Score — The Secret to Cheap Clicks

Your Quality Score (1–10) is Google’s grade for how relevant and useful your ad is. Three things determine it:

Quality Score Breakdown
K
Keyword Relevance
Does your ad match the search?
3/10
L
Landing Page
Fast, relevant, mobile-friendly?
4/10
C
Expected CTR
Will people click your ad?
3/10
Total Quality Score: 10/10
A perfect 10 means you pay the lowest CPC in the auction

Your First Google Search Campaign in 5 Steps

1

Choose Your Goal & Campaign Type

Go to ads.google.com → New Campaign. Pick a goal:

Website trafficSend people to your site
LeadsGet calls, form submissions
SalesDrive online purchases
Brand awarenessBetter for Display/YouTube later
2

Pick Your Keywords

Keywords are the search terms you want your ad to appear for. Use Google’s free Keyword Planner to find them.

Match Types
Broad Match
running shoes
Widest reach, less control
Phrase Match
"running shoes"
Balanced reach & relevance
Exact Match
[running shoes]
Tightest control, fewer clicks

Beginner tip: Start with Phrase Match for the best balance. Add 10–20 keywords, and add negative keywords to block irrelevant searches (e.g., “free” if you sell products).

\u2705 Set a max CPC bid limit (e.g., $2)
\u23F3 Switch to Target CPA once you have 30+ conversions
4

Write Your Ad Copy

Google Search ads use Responsive Search Ads (RSA). You provide up to 15 headlines and 4 descriptions — Google mixes and matches to find the best combo.

Adwww.yoursite.com
Headline 1 | Headline 2 | Headline 3
Description line that explains your offer clearly. Include a call-to-action.
Sitelink 1Sitelink 2Sitelink 3

3 Rules for Google Ad Copy

1
Include the keyword in Headline 1
If they searched "running shoes", your headline should say "running shoes".
2
Show a clear benefit or offer
"Free Shipping" or "50% Off" beats vague claims every time.
3
Use all available extensions
Sitelinks, callouts, structured snippets make your ad bigger and cheaper.
5

Launch & Set Up Conversion Tracking

Install the Google Ads tag on your website before launching. Without conversion tracking, you’re flying blind — you won’t know which keywords actually drive sales. Go to Tools → Conversions → New conversion action.

The ideal strategy? Use Facebook Ads to get people interested (awareness), then Google Ads to catch them when they search (conversion). They work best together.

People are searching for what you sell.
Be the answer they find.

Google Ads isn’t magic — it’s math. The right keywords, a relevant ad, and a good landing page. Start small, measure everything, and scale what converts.
