Google Ads Keywords: A Simple Beginner’s Guide

Imagine you sell school bags.

A person opens Google and searches:

“best school bags for kids”

You want your advertisement to appear because that person might become your customer.

But how does Google know that your advertisement is related to that search?

One important part of the answer is keywords.

Let us understand Google Ads keywords as simply as possible.

What are Google Ads Keywords?

Google Ads keywords are words or phrases that advertisers use to help connect their Search ads with relevant searches.

For example, if you sell running shoes, you might use keywords such as:

running shoes
buy running shoes
men's running shoes
women's running shoes
sports shoes online

When people search for related things, Google can consider your advertisement for the auction.

However, a keyword is not a guarantee that your ad will appear.

Google considers your keyword, the user's search, your campaign settings, your ad, your landing page, the auction and other factors.

Google Ads Keywords Example

Let us imagine you own an online shoe shop.

Your keyword:

running shoes

Someone searches:

“best running shoes for beginners”

Google may determine that the search is relevant to your keyword and consider your ad for the auction.

Your advertisement might say:

Comfortable Running Shoes
Shop Shoes for Every Workout
Order Online Today

The person clicks the ad and visits your website.

That is the basic idea.

Why Are Keywords Important?

Keywords help advertisers tell Google:

“These are the types of searches that are relevant to my business.”

Good keywords can help you reach people who are genuinely interested in your product or service.

Bad keywords can waste money by attracting people who are not likely to become customers.

So keyword selection is an important part of a Search campaign.

What Makes a Good Google Ads Keyword?

A good keyword should be closely connected to what you are offering.

Imagine you sell birthday cakes.

Good keywords

birthday cakes
birthday cake delivery
custom birthday cakes
order birthday cake online
chocolate birthday cake

Poor keywords

free cake recipes
cake wallpaper
cake photos
history of cakes

Why?

Someone searching for “cake wallpaper” probably is not looking to buy your cake.

Someone searching for “birthday cake delivery” may be ready to order.

The second type of search can be much more valuable to a cake business.

Keyword vs Search Term

These two terms are often confused.

Keyword

The word or phrase you choose in your Google Ads campaign.

Example:

birthday cake delivery

Search term

The actual words a person enters into Google.

Example:

“same day birthday cake delivery near me”

The search term may not be exactly identical to your keyword.

Google's keyword matching system can use the meaning and intent of searches rather than requiring an exact word-for-word match.

Google Ads Keyword Match Types

Google Ads provides different keyword match types to control how closely a search should relate to your keyword.

The main match types are:

Broad match
Phrase match
Exact match

Let us make them easy to understand.

1. Broad Match

Broad match gives Google more freedom to find searches related to the meaning of your keyword.

Example keyword:

running shoes

Google may consider searches related to running footwear and similar intent.

Advantage

You can reach a wider range of relevant searches.

Disadvantage

You generally have less direct control over exactly which searches can trigger your ad.

Broad match can be useful when you want Google to find additional relevant opportunities, particularly when using appropriate conversion-focused bidding and good campaign data.

2. Phrase Match

Phrase match gives you more control while still allowing searches that have the same meaning or intent.

Example:

"running shoes"

A person's search could be something like:

best running shoes for beginners

The search does not necessarily need to be exactly the same words.

Google's current phrase matching system focuses on the meaning of the keyword in relation to the search.

3. Exact Match

Exact match gives you tighter control over the searches your keyword can match.

Example:

[running shoes]

It does not mean that only the exact three words can trigger your advertisement.

Google's current exact-match system can match searches that have the same meaning or intent, including close variations.

Simple way to remember

Broad → More reach

Phrase → More control

Exact → Tighter control

What Are Negative Keywords?

This is one of the most useful Google Ads concepts.

A negative keyword tells Google:

“Do not show my advertisement for searches related to this unwanted term.”

Imagine you sell expensive professional cameras.

You do not want to pay for people searching for:

free camera

You could add relevant negative keywords such as:

free

This can help prevent your ads from appearing for searches that are not useful to your business.

Negative keywords are particularly useful for reducing irrelevant traffic and wasted advertising spend.

Positive vs Negative Keywords

Think of it like a door.

Regular keyword

“People interested in my product can come in.”

Negative keyword

“People searching for this unwanted thing should stay out.”

Using both can help you control your advertising traffic.

How Many Keywords Should You Use?

There is no magic number.

A beginner should not try to add thousands of keywords simply because more seems better.

Instead, organize your keywords around closely related products or services.

For example, a shoe store might have groups such as:

Running Shoes

running shoes
buy running shoes
men's running shoes
women's running shoes

Walking Shoes

walking shoes
comfortable walking shoes
shoes for walking

Sports Shoes

sports shoes
athletic shoes
training shoes

This makes your campaigns easier to organize and your advertisements more relevant.

What is Keyword Research?

Keyword research means finding out what words and phrases potential customers use when searching for products or services.

Imagine you sell handmade jewellery.

You might discover searches such as:

handmade jewellery
handmade jewellery online
handmade earrings
silver earrings for women
handmade jewellery gifts

You then decide which searches are actually useful for your business.

How to Find Google Ads Keywords

You can start by thinking like your customer.

Ask:

“If I wanted to buy this product, what would I type into Google?”

Then consider:

Product

running shoes

Buying intent

buy running shoes online

Location

running shoes near me

Specific product

women's Nike running shoes

Problem

best shoes for long-distance running

The more you understand your customer, the easier keyword research becomes.

Use Google's Keyword Planner

Google provides Keyword Planner as part of Google Ads.

It can help advertisers discover keyword ideas and research search-related information for campaigns.

You can start with a product, service or website and explore related keyword ideas.

This is especially useful when you are building a Search campaign.

High-Intent Keywords

Some keywords suggest that a person is closer to making a purchase.

Compare:

Lower commercial intent

how are running shoes made

with:

Higher commercial intent

buy running shoes online

The second search clearly sounds more like someone who wants to purchase.

This does not mean informational keywords are useless.

It simply means you should understand search intent.

What is Search Intent?

Search intent means:

What does the person actually want when they search?

For example:

Informational

what are running shoes

The person wants information.

Commercial

best running shoes for beginners

The person is researching options.

Transactional

buy running shoes online

The person may be ready to purchase.

Understanding intent helps you choose keywords and advertisements that match what the customer wants.

Long-Tail Keywords

A long-tail keyword is generally a more specific search phrase.

Compare:

shoes

with:

best running shoes for women under ₹3000

The second phrase is much more specific.

It may have fewer searches, but it can sometimes attract people with a clearer need.

For many businesses, specific and relevant searches can be valuable.

Do not Choose Keywords Only by Search Volume

This is a common beginner mistake.

Imagine these two keywords:

shoes

10,000 searches

buy men's running shoes online

1,000 searches

The first keyword has more searches.

But if you sell men's running shoes, the second keyword may be much more closely connected to your product.

So do not ask only:

“Which keyword gets the most searches?”

Also ask:

“Which keyword is most likely to bring me a valuable customer?”

Keyword Competition

Some keywords have many advertisers competing for them.

More competition can make advertising opportunities more expensive.

For example, a keyword related to a valuable service may attract many businesses because one customer can be worth a lot of money.

This is one reason there is no universal “Google Ads keyword price.”

Cost Per Click and Keywords

Keywords can influence advertising costs, but a keyword does not have one permanent price.

The actual cost of a click depends on the advertising auction and many other factors.

For example, suppose:

Keyword: emergency plumber

One click might cost more than a click for a less competitive search.

Your actual CPC can vary from auction to auction.

Keyword Quality Matters

Do not simply collect keywords.

Make sure your:

Keyword → Advertisement → Landing page

all make sense together.

Example

Keyword:

women's running shoes

Women's Running Shoes – Shop Online

Landing page:

Women's Running Shoes Collection

That is a logical journey.

But:

Keyword:

women's running shoes

Men's Formal Shoes

Landing page:

Mobile Phone Accessories

That is confusing.

A strong campaign keeps these elements closely connected.

Common Google Ads Keyword Mistakes

Mistake 1: Using extremely broad keywords

A keyword such as:

shoes

could be too broad for a specialist shoe business.

Mistake 2: Ignoring negative keywords

You could pay for irrelevant clicks.

Mistake 3: Choosing keywords unrelated to your product

High search volume does not help if visitors do not want what you are selling.

Mistake 4: Focusing only on search volume

More searches do not automatically mean more customers.

Mistake 5: Forgetting search intent

Understand why people are searching.

Mistake 6: Adding hundreds of keywords without organization

More is not always better.

Keep closely related keywords organized into sensible groups.

Simple Google Ads Keyword Strategy for Beginners

Here is an easy starting method.

Step 1

Write down your main product.

Running shoes

Step 2

Add buying phrases.

buy running shoes

running shoes online

Step 3

Add specific variations.

women's running shoes

men's running shoes

Step 4

Think about customer problems.

best running shoes for beginners

Step 5

Think about location if you are a local business.

running shoes near me

Step 6

Find unwanted searches.

For example:

free running shoes

If those searches are not useful to your business, consider appropriate negative keywords.

Step 7

Group related keywords.

Keep similar products and search intent together.

Google Ads Keywords Example

Let us imagine Simran sells cakes in Jalandhar.

Her main product is:

Birthday cakes

Possible keywords:

birthday cakes
birthday cake delivery
birthday cake online
custom birthday cakes
chocolate birthday cake
birthday cakes near me

Possible unwanted searches:

free cake recipe
cake wallpaper
cake images

She could investigate these searches and add suitable negative keywords where appropriate.

Her advertisement could say:

Birthday Cakes in Jalandhar

Fresh Custom Cakes – Order Online

Same-Day Options Available

Her landing page should show the relevant cakes.

Now the entire customer journey makes sense:

Search → Keyword relevance → Advertisement → Cake page → Order

Frequently Asked Questions

What are Google Ads keywords?

They are words or phrases advertisers use to help connect Search advertising with relevant searches.

Are Google Ads keywords free?

Adding keywords to a campaign does not itself have a fixed fee. You generally pay according to your campaign's applicable advertising model when your ads receive interactions or achieve other billable outcomes.

What are the three Google Ads match types?

The main keyword match types are broad match, phrase match and exact match.

Which match type is best?

There is not one match type that is best for every campaign. Your choice depends on your goals, level of control, campaign data and bidding strategy.

What are negative keywords?

Negative keywords help prevent your ads from showing for searches containing unwanted terms or meanings, depending on the campaign's matching behavior.

How many keywords should I use?

There is no perfect number. Start with highly relevant keywords and organize them logically rather than adding large numbers of unrelated terms.

What is the difference between a keyword and a search term?

A keyword is something you add to your campaign. A search term is what the user actually typed or expressed in their search.

Final Thoughts

Google Ads keywords are basically signposts.

They help tell Google:

“My business is relevant to people looking for this.”

But successful keyword selection is not about finding the biggest possible list.

It is about finding relevant searches from people who are likely to value what you are offering.

Remember this simple formula:

Right keyword + Right customer + Right advertisement + Right landing page = Better chance of a useful result

And do not forget:

More searches ≠ automatically more sales.

The best keyword is often the one that connects your business with the right customer at the right moment.
