How to do Keyword Research for Google Ads


Keyword research is one of the most important parts of building a successful Google Ads campaign. 

The right keywords help businesses reach users who are actively searching for products or services related to their business. Effective keyword targeting improves ad relevance, increases click-through rates (CTR), and boosts conversions while reducing wasted ad spend.

In Google Ads, keywords trigger ads to appear in search engine results pages (SERPs). Choosing highly relevant and high-intent keywords ensures that ads are shown to users who are most likely to take action, such as making a purchase, filling out a contact form, or requesting a service.

A strong keyword strategy combines search intent analysis, keyword match types, competitor research, and negative keyword optimization to maximize campaign performance and return on investment (ROI).

Businesses can use tools like Google Keyword Planner, Google Trends, and Search Terms Reports to discover valuable keywords and improve campaign targeting.

Finding High-Intent Keywords

High-intent keywords are search terms used by people who are ready to take action. These users often have strong purchase intent, meaning they are more likely to convert into customers. Targeting high-intent keywords helps businesses attract qualified traffic and improve conversion rates.

Unlike informational keywords, high-intent keywords usually contain words that indicate buying behavior, urgency, or decision-making intent.

Examples of High-Intent Keywords

  • buy running shoes online

  • best digital marketing agency near me

  • affordable web design services

  • emergency plumber in Delhi

  • Google Ads management company

  • order birthday cake online

These keywords often include commercial phrases such as:

  • buy

  • hire

  • order

  • near me

  • best

  • affordable

  • discount

  • service provider

Benefits of High-Intent Keywords

  • Higher conversion rates

  • Better lead quality

  • Improved ROI

  • Reduced wasted clicks

  • Increased sales opportunities

  • More relevant traffic

Businesses should focus on keywords that align closely with customer intent and landing page content. Long-tail keywords are especially valuable because they are more specific and often have lower competition and higher conversion potential.

Best Practices for Finding High-Intent Keywords

  • Use Google Keyword Planner for keyword ideas

  • Analyze customer search behavior

  • Focus on long-tail search phrases

  • Study competitor keywords

  • Monitor Search Terms Reports

  • Target location-based keywords for local businesses

Using Keyword Match Types

Keyword match types determine how closely a user’s search query must match your selected keywords before your ads appear. Choosing the correct match type helps advertisers control targeting accuracy, traffic quality, and advertising costs.

Google Ads offers different keyword match options that balance reach and relevance.

Main Keyword Match Types

Broad Match

Broad match allows ads to appear for searches related to your keywords, including synonyms and variations.

Example:

Keyword: running shoes

Possible searches:

  • sports shoes

  • jogging sneakers

  • athletic footwear

Benefits:

  • Wider audience reach

  • More traffic opportunities

  • Helpful for keyword discovery

Drawbacks:

  • May trigger irrelevant searches

  • Higher risk of wasted ad spend


Phrase Match

Phrase match displays ads for searches containing the meaning of your keyword phrase.

Example:

Keyword: "running shoes"

Possible searches:

  • best running shoes for men

  • affordable running shoes online

Benefits:

  • Better targeting control

  • Higher relevance than broad match

  • Improved conversion potential


Exact Match

Exact match targets searches with the same meaning or intent as the keyword.

Example:

Keyword: [running shoes]

Possible searches:

  • running shoes

  • shoes for running

Benefits:

  • Highly targeted traffic

  • Better conversion rates

  • Reduced irrelevant clicks

Drawbacks:

  • Lower traffic volume

Why Match Types Matter

Using the correct match types helps businesses:

A balanced keyword strategy often combines broad, phrase, and exact match keywords for optimal results.

Adding Negative Keywords

Negative keywords prevent ads from appearing for irrelevant searches. They are essential for reducing wasted ad spend and improving campaign targeting. Without negative keywords, businesses may receive clicks from users who are not interested in their products or services.

For example, a premium digital marketing agency may add words like “free” or “cheap” as negative keywords to avoid attracting low-intent users.

Examples of Negative Keywords

  • free

  • cheap

  • jobs

  • careers

  • tutorial

  • DIY

  • used

  • sample

Benefits of Negative Keywords

  • Reduces irrelevant traffic

  • Improves conversion rates

  • Saves advertising budget

  • Enhances audience targeting

  • Improves click-through rate (CTR)

  • Increases campaign efficiency

Businesses should regularly review Search Terms Reports to identify irrelevant searches and add them as negative keywords.

Types of Negative Keywords

  • Negative broad match

  • Negative phrase match

  • Negative exact match

Best Practices for Negative Keywords

  • Monitor search queries weekly

  • Exclude unrelated topics

  • Remove low-converting searches

  • Use industry-specific exclusions

  • Create shared negative keyword lists

Proper use of negative keywords can dramatically improve ad relevance and lower cost-per-click (CPC).
