A crucial aspect of any successful Google Ads campaign is keyword selection. Choosing the right keywords can make or break your campaign, determining your reach, relevance, and ultimately, your return on investment.

This comprehensive guide will walk you through the essential criteria for selecting keywords using the Google Keyword Planner and provide insights into how many keywords to focus on initially.

Understanding Google Keyword Planner

Before diving into keyword selection criteria, it's essential to understand how to use the Google Keyword Planner effectively. This free tool, accessible through your Google Ads account, allows you to research and analyze keywords, discover new keyword ideas, and get search volume and forecast data.

To use the Keyword Planner effectively, follow these steps:

- Access Keyword Planner: Sign in to your Google Ads account and navigate to the Keyword Planner through the "Tools and settings" menu.

- Discover New Keywords: Choose the "Discover new keywords" option to generate keyword ideas. You can start with a website, enter keywords, or upload a list of keywords. You can also utilize the "Product Category" option. This allows you to select which product categories best describe your business to discover popular keywords frequently searched within your...source

- Refine Your Keyword List: Filter the results based on your preferences, such as location, language, and search volume.

- Look at Search Volumes: Analyze the average monthly searches for each keyword to understand its potential reach.

- Separate PPC Keywords from SEO Keywords: Identify keywords that are more suitable for paid advertising versus organic search optimization.

- Evaluate Competition Levels: Assess the competition for each keyword, as higher competition generally means higher costs.

- Get PPC Forecasts: Use the forecast tool to estimate the potential performance of your keywords based on different bidding strategies and budgets.

In addition to discovering and analyzing keywords, Google Keyword Planner also allows you to organize keywords into ad groups. This feature enables you to group similar keywords together, which can improve the relevance of your ads and potentially increase your Quality Score. By organizing your keywords into ad groups, you can create more targeted campaigns and ensure that your ads are shown to the most relevant audience.

Keyword Selection Criteria

Now that you're familiar with the Keyword Planner, let's explore the key criteria for selecting the right keywords for your Google Ads campaign:

1. Keyword Match Types

Understanding keyword match types is crucial for controlling how your ads appear in search results. There are three primary match types:

Match TypeDescriptionExampleBroad MatchThis is the default match type and offers the widest reach. Your ads may show for searches that include misspellings, synonyms, related searches, and other variations of your keyword.If your keyword is "women's hats," your ad might appear for searches like "buy ladies hats" or "hats for women."Phrase MatchThis match type offers a more targeted approach. Your ads will only show for searches that include the exact phrase you've specified, in the same order.If your keyword is "running shoes," your ad will show for searches like "best running shoes" or "running shoes for women" but not for "shoes for running."Exact MatchThis is the most restrictive match type, offering the highest relevance but the lowest reach. Your ads will only show for searches that exactly match your keyword, including close variations like plurals and misspellings.If your keyword is , your ad will only show for searches that are exactly "tennis shoes" or very close variations like "tennis shoe" or "tenisshoes."

It's important to remember that there's a trade-off between reach and relevance when it comes to keyword match types. Broad match offers the widest reach but may result in less relevant traffic, while exact match provides the highest relevance but limits your reach. Phrase match offers a balance between the two.

In addition to these match types, you can also use negative keywords to further refine your targeting. Negative keywords allow you to exclude your ads from showing for certain search terms. There are three negative keyword match types:

- Negative broad match: Your ad won't show if the query contains all your negative keywords in any order.

- Negative phrase match: Your ad won't show if the query contains your negative keywords in the exact order you specify.

- Negative exact match: Your ad won't show if the query contains the exact phrase of your negative keyword, with no other words.

2. Keyword Relevance

Keyword relevance is paramount. Your chosen keywords should be closely related to your products or services and align with the search intent of your target audience. If your keywords are not relevant, your ads will be shown to users who are not interested in what you offer, leading to wasted ad spend and low conversion rates.

To determine keyword relevance, consider the following:

- User Intent: What are users looking for when they search for a particular keyword? Are they looking for information, to make a purchase, or to compare products?

- Landing Page Relevance: Does the content on your landing page match the keywords you're targeting?

- Keyword Difficulty: Keyword difficulty scores, provided by tools like SEMrush, can help you assess the competitiveness of a keyword. It's generally recommended to target keywords with a low to medium difficulty score (below 50) and a high search volume (above 1000). These keywords are more likely to have less competition and more demand from users.

3. Search Volume

Search volume indicates how many people are searching for a particular keyword. High search volume keywords generally have greater potential to drive traffic to your website. However, they also tend to be more competitive, which can increase your ad costs.

It's important to note that "substantial search volume" is relative to your niche. A keyword with a high search volume in one industry might have a low search volume in another. To determine what constitutes a high search volume for your business, analyze the average search volume for your chosen keywords and compare them to industry benchmarks.

4. Long-Tail vs. Short-Tail Keywords

Long-tail keywords are longer, more specific phrases that target niche audiences. For example, instead of targeting the short-tail keyword "shoes," you might target the long-tail keyword "women's running shoes for flat feet." While long-tail keywords have lower search volume than short-tail keywords, they often have higher conversion rates because they attract users who are further along in the buying cycle and have a more specific idea of what they're looking for.

Short-tail keywords, on the other hand, are broader terms with higher search volume but more competition. They are often used in the early stages of research when users are still exploring their options.

5. Negative Keywords

Negative keywords are terms that you want to exclude from your campaigns. They prevent your ads from showing for irrelevant searches, saving you money and improving your campaign's efficiency. For example, if you sell "hiking boots" but not "work boots," you would add "work boots" as a negative keyword.

Using negative keywords can also have a positive impact on your click-through rate (CTR) and conversion rate. By ensuring that your ads are only shown to a more relevant audience, you can increase the likelihood that users will click on your ads and convert.

6. Keyword Competition

Keyword competition refers to the number of advertisers bidding on a particular keyword. High competition generally means higher ad costs. When selecting keywords, it's crucial to find a balance between search volume and competition to maximize your return on investment.

You can use the "Competition" tab in Google Keyword Planner to assess the competitiveness of a keyword. This tab provides insights into the number of advertisers bidding on a keyword and can help you make informed decisions about your bidding strategy. A common strategy is to ignore the really expensive keywords and go after the less competitive long-tail... Source generated a list of potential keywords, it's important to refine your list to ensure that you're targeting the most relevant keywords for your business and target audience. You can refine your keyword list in Google Keyword Planner by filtering for location, language, and search volume.

- Location: If you're a local business, you'll want to target keywords that are relevant to your geographic area.

- Language: Ensure that you're targeting keywords in the language that your target audience speaks.

- Search Volume: Filter your list to focus on keywords with a search volume that aligns with your campaign goals and budget.

Optimal Number of Keywords to Focus on Initially

Now that we've explored the key criteria for selecting keywords, let's discuss how many keywords you should focus on when starting your Google Ads campaign. While there's no one-size-fits-all answer to this question, a good starting point is to focus on a smaller number of highly relevant keywords. Some experts recommend starting with 5-10 keywords per ad group, while others suggest up to 30.

Factors to consider when determining the optimal number of keywords include:

- Campaign Objectives: If your goal is brand awareness, you might cast a wider net with more keywords. If your goal is lead generation or sales, a more focused approach with fewer, highly relevant keywords might be more effective.

- Budget: A larger budget allows for more keywords, while a smaller budget may necessitate a more targeted approach.

- Industry and Competition: Highly competitive industries may require more keywords to capture relevant traffic.

It's essential to strike a balance. Too few keywords can limit your reach, while too many can dilute your campaign's effectiveness. Start with a manageable number of keywords and gradually expand your list as you gather data and optimize your campaigns.

It's also important to remember that keyword quality is more important than quantity. You're better off targeting 10 high-quality keywords in your ad than 50 low-quality keywords. Focus on choosing keywords that are highly relevant to your business and have a good chance of converting.
