PPC keyword analysis is crucial for driving targeted traffic to websites and boosting conversion rates. By bidding on the right keywords for your pay-per-click (PPC) ad campaign, you can increase your brand’s visibility, placing your offerings front and center on search result pages (SERPs). But how do you determine which PPC keywords to bid on?

In this article, we discuss the different types of PPC keywords, how to identify the best ones for your campaign, and our top PPC keyword research tools. With these insights, you’ll be well-equipped to optimize your keyword strategy and reap the benefits of PPC.

Key Takeaways

  • PPC keyword research enables businesses to identify high-performing, highly relevant keywords to target interested customers and increase conversions.
  • Regularly reviewing and updating keywords based on performance metrics is crucial for long-term success.
  • PPC research and paid ad management tools like Google Keyword Planner, WordStream, and SpyFu provide actionable data to optimize campaigns.

What Are PPC Keywords?

PPC keywords are search terms you bid on to secure your PPC ad placement at the top of SERPs. By identifying and bidding on high-performing keywords with strong search intent, you can attract consumers who are actively searching for relevant products or services and reap the benefits of PPC. When you bid correctly, your PPC ads will appear in front of the right people at the right time, increasing the likelihood of converting them into paying customers.

Additionally, you can use these keywords to craft compelling ad copy and optimize landing pages and calls to action (CTAs) for maximum conversions. Effective PPC keyword analysis will help enhance ad targeting, streamline ad spending, and increase return on investment (ROI).

What Are PPC Keywords

Types of Keywords in PPC

PPC keyword research involves a deep understanding of different types of keywords to utilize them correctly. There are six types of PPC keywords:

  1. Brand keywords
  2. Generic keywords
  3. Long-tail keywords
  4. Locational keywords
  5. Competitive keywords
  6. Negative keywords

1. Brand Keywords

Brand keywords include your brand name and other search terms (the words your user types into Google) related to your brand. Brand keyword examples include “Nike.com” and “Nike shop.”

A brand-plus keyword includes your brand name and a qualifying phrase. Examples of brand-plus keywords include “Nike running shoes” along with many variations, including:

  • Brand + product name (“Nike Air Max”)
  • Brand + long-tail keyword (“Nike Air Zoom running shoe size 13”)
  • Brand + sale (“Nike discount” or “Nike sale”)
  • Brand + coupon (“Nike coupon”)
  • Brand + review (“Nike Air Jordan review”)
  • Brand + website (“www.Nike” or “Nike website”)

2. Generic Keywords

Generic keywords are non-specific search terms relevant to your brand’s products or services. These short-tail and broad terms have high search volumes and can be difficult to rank for in a crowded industry. However, incorporating them into your keyword strategy will help you gather data on consumer behavior and identify more specific niche keywords with lower competition.

Let’s say you own a retail store for sports and fitness. When you begin the PPC research process, you can list common terms such as “running shoes,” “yoga pants,” and “compression shorts” to start.

3. Long-Tail Keywords

Long-tail keywords are highly specific terms often three words or longer, and they cater to niche markets. They generate lower search volumes compared to generic terms and are less competitive, but they fetch higher conversion rates because they indicate very strong purchase intent. When you target long-tail keywords, you can more precisely target audiences, attract more qualified leads, and increase ROI.

An example of a long-tail keyword is “Nike running shoes for a triathlon.”

4. Locational Keywords

Locational keywords allow marketers to target audiences based on specific cities, regions, and even neighborhood terms that potential customers may use. You can use these to push your ads to potential customers in relevant locations, attract local traffic, and increase revenue.

Examples of locational keywords include “retail store San Francisco” or “sports retail stores near me.”

5. Competitive Keywords

Competitive keywords are search terms that are relevant to your brand’s competitor(s). Investing in these keywords allows you to put your brand and offerings front and center for users looking up your competitor’s products or services.

For example, when a user searches for “Sony TV,” a Samsung TV PPC ad with a message like “Switch to Samsung TVs” can appear. Samsung’s tongue-in-cheek approach may entice those who are not fully committed to purchasing a Sony TV, convincing them to consider a Samsung TV instead.

6. Negative Keywords

Negative keywords prevent your PPC ads from appearing in searches that are unlikely to result in conversions. By excluding these irrelevant terms, you can minimize wasted ad spending and target consumers more effectively.

For instance, if you own a beachfront villa and are creating PPC ad campaigns for the target keywords “beachfront villa” or “beachfront vacation,” you’d want to avoid appearing in searches for terms like “hillside villa” or “hillside vacation.” You can add them as your negative keywords.

PPC is favored by marketers and business owners to increase visibility and target relevant audiences. Competition across industries is fierce, which is why it is important to develop and deploy effective paid ad campaigns.

The most crucial element of a successful paid ad strategy is finding the right keywords. Here’s a step-by-step guide to keyword research for PPC:

  1. Define your PPC goals
  2. Establish your audience
  3. Understand search intent
  4. Brainstorm keyword ideas
  5. Perform competitor research
  6. Conduct keyword research
  7. Group your keywords into ad groups
  8. Track keyword performance

1. Define Your PPC Goals

First, determine what you want to achieve with your PPC campaign. Do you want to increase brand awareness? Boost revenue? Improve lead generation? Define SMART (Specific, Measurable, Achievable, Relevant, and Time-Bound) goals that will guide your PPC strategy.

For example, you want to increase the number of leads generated from your latest PPC campaign.

  • Specific: Specify the type of leads you want (e.g., signups, contact form submissions, reservations, etc.).
  • Measurable: Quantify your goals so you can track your progress and measure success (e.g., increase newsletter signups by 20% each month).
  • Achievable: Set realistic goals based on your current ad performance and market conditions (e.g., you are currently getting 50-100 signups per month, so capturing 10-20 more leads is achievable).
  • Relevant: Make sure your PPC objectives align with overall business goals (e.g., more newsletter signups mean more opportunities to convert interested leads into paying customers).
  • Time-bound: Set a deadline to maintain focus and urgency (e.g., maintain a minimum 20% increase in signups in the next 12 months). Use PPC tools to track milestones and deadlines to help you achieve your goals.

2. Establish Your Target Audience

When you have a well-defined target market for your PPC campaigns, your ads will reach the right people and achieve better results. Here are some steps to establish your target audience:

  • Identify your ideal customer demographics, needs, pain points, preferences, and behavior.
  • Study your own customer data, access industry reports, and perform competitive analysis to understand the broader market landscape.
  • Collect customer feedback to understand why your current customers choose your offerings over others.

With these details, you can refine your campaign targeting and write ad copy that will resonate with the audience you want to reach.

3. Understand Search Intent

Understanding search behavior and intent is crucial for effective PPC keyword research. These are the main types of search intent:

Type of Search Intent User Actions PPC Strategy Keyword Examples
Informational Users are looking for answers to specific questions. They are not necessarily looking to purchase anything.Link to informative content that provides what they need.
  • what is PPC advertising?
  • vacation ideas seaside
Commercial Users have progressed into the product research phase but are not yet ready to make a purchase.Use keywords that answer common customer questions.
  • Asics vs Hoka shoes
  • Windows laptops comparison
Transactional Users are ready to make a purchase and can be compelled to click on ads offering discounts and promotions.Use conversion-oriented keywords and strong CTAs.
  • discounts for running shoes 2025
  • deals for Dell laptops
Navigational Users are trying to find a specific website, usually for brands.Use branded keywords to capture traffic looking for your site.
  • Pinterest login
  • Netflix signup
Local Users looking for nearby businesses.Use location-based keywords to drive in-store traffic.
  • running shoes near me
  • tech store in Manhattan

4. Brainstorm Keyword Ideas

Put yourself in the shoes of your target audience and think of the terms they’re most likely to type on the search bar to look for your products. It might be overwhelming to brainstorm every single keyword possible, so start with each type we listed above: brand, generic, long-tail, locational, competitive, negative keywords as exact, broad, or phrase keyword match.

Utilize tools like Google Keyword Planner and Ahrefs for relevant keywords, search volumes, competition levels, difficulty, traffic potential, and more.

5. Perform Competitor Research

Next, find out what your competitors are doing for their PPC ad campaigns. By performing competitor research, you can find which keywords other websites are bidding on and what they’re ranking for.

Use SpyFu and Ahref’s competitor tools for a detailed look into your competitor’s ads, including their keyword strategy, ad copy, positions, history, and more.

Conducting a SWOT analysis can provide a comprehensive understanding of your market position and inform your PPC strategy moving forward:

  • Strengths: Identify what competitors are doing well, such as the keywords driving significant traffic, ad copy effectiveness, and landing page design.
  • Weaknesses: Look at where your competitors are lacking, such as keywords with low engagement or high bounce rates, generic ad copy, and unclear CTAs.
  • Opportunities: Leverage trends or seasonal keywords your competitors aren’t using yet and look for long-tail keywords that are underserved in your niche.
  • Threats: Competitors with bigger budgets and more established brand recognition may be outbidding you consistently, and new competitors may have more aggressive PPC strategies.

6. Conduct Keyword Research

After brainstorming and competitor research, it’s time to take your keywords list and refine it. To help you with creating your list and deciding on the keywords to use for your PPC ad, use a keyword research tool such as Google Keyword Planner.

With Google’s Keyword Planner, you can discover:

  • A keyword’s click-through rate (CTR)
  • A keyword’s quality score or the metric to rate your ad campaign
  • A keyword’s rate or cost-per-click
  • A keyword’s potential impressions or how many times the keyword is displayed on search engine result pages (SERPs)

In this stage, consider which keywords are out of your budget and which are worth spending on. In 2025, the average cost-per-click (CPC) in Google Ads is $1-4.

7. Create Ad Groups

Once you’ve narrowed down the list of keywords you want to target, organize them into PPC ad groups. These are keywords grouped by theme, intent, and granularity to enhance audience targeting and ad relevance.

Let’s say you have an ad campaign focused on an outdoor grill sale. You can create two ad groups for your PPC campaign with two or more ads in each group:

  • Gas grills: You can include “natural gas grills,” “propane gas grills,” and variations. These ads will lead users to your gas grill landing page.
  • Smoker grills: You can use “meat smokers,” “charcoal smoker grills,” and similar terms that will lead to your landing page for smoker grills.

Ultimately, PPC ad groups assist your PPC optimization efforts by enabling you to choose your target audiences and the specific keywords you can use to capture your target groups. Optimize ad copy and enhance your landing pages to ensure alignment with keywords and increase conversions.

8. Track Keyword Performance

Closely monitoring PPC performance will help you optimize your campaigns, manage your budget, and improve ROI. Monitor the following key metrics to know how your ads are being received:

  • Click-through rate: The percentage of people who click on your ad
  • Conversion rate: The percentage of clicks that result in a conversion
  • Cost per click: The average amount you pay for each click
  • Cost per conversion: The average amount you pay for each conversion
  • Quality score: Google Ads metric that measures the relevance of your ads, keywords, and landing pages

Furthermore, analyze performance trends for your keywords (high performers vs. underperformers), ad copy variations, and landing pages. Optimize your campaign based on these insights — you can adjust your bid strategy, incorporate new keywords that show potential, remove underperforming keywords, and optimize accordingly.

Custom reports, performance dashboards, and A/B testing features provided by PPC tools will help with these tasks.

Keyword Match Types For PPC

Keyword match types determine how closely search phrases must match your keyword for your ad to be considered in the auction. Each one provides a different level of control over who sees your ads:

  1. Broad match
  2. Exact match
  3. Phrase match

1. Broad Match

A broad keyword match combines keywords that include synonyms, misspellings, words that aren’t in order, related searches, and any other search terms that Google considers relevant. It provides the broadest reach but can lead to irrelevant clicks.

For example, if your user searches for “bik shop” (misspelled) or “cycle store” (related search), but the keyword you’re targeting is “bike shop,” your PPC ad will still appear on SERPs.

2. Exact Match

An exact keyword match shows your ad only when the exact search term is entered into Google or when a close search term variant is being used. This provides the highest level of control over who will see your ad.

Again, let’s say your target keyword is “bike shop.” If a user looks up “bike sohp” on Google, which is misspelled, your ad won’t appear. A user would have to correctly spell “bike shop” or “shop for bikes” (the same meaning) to see your ad.

3. Phrase Match

A phrase keyword match displays PPC ads only when the words in the search term are in the proper order. Unlike broad match or even exact match, phrase match doesn’t accommodate articles within your target phrase.

For your PPC ad campaign to appear, the search query must exactly match the phrase and contain every keyword or close variant, including abbreviations, singular/plural versions, and close misspellings.

So, if your target keyword is “bike shop,” and a user searches for “local bike shop” your PPC ad campaign will appear. However, if a user searches for “bike local shop,” your PPC ad campaign won’t appear.
