Without the right keywords, no ad campaign will work. The success of any PPC campaign depends not just on budget or creative ad copy. If your ads are shown to the wrong people, you won’t get results. You could be paying for clicks that never turn into leads, sales, or subscriptions.

Keywords are the bridge between a user and your website. It’s often during the keyword selection phase that budgets get “wasted.” In this article, we’ll show you how to properly choose keywords for truly effective advertising.

What are Keywords in PPC Advertising?

These are the phrases users type into search engines—Google uses them to decide which ads to display. For example, if someone searches for “buy car lamp,” your website might appear in response to that query, but only if that specific keyword is in your campaign settings.

But it’s crucial: you don’t want to show up for everything that sounds similar, only for terms that genuinely lead to your goal. That’s what your effective keyword will be.

Types of Keywords

They are generally divided into three types:

• Broad/General: “laptop,” “training,” “lamp” — these are highly competitive and don’t filter the audience well.

• Medium-tail: “laptop for studying,” “marketing training” — these are more targeted.

• Exact/Long-tail: “buy HP laptop with backlit keyboard” — fewer impressions, but a precise match to the query.

Ideally, combine these types to reach your target audience at different stages of their decision-making process.

How to Gather Keywords: Step-by-Step

• Start with yourself. Imagine how you would search for your own product or service. Create a list of these queries.

• Look on Google. Type these words into the search bar and see what the system suggests—these are popular phrases.

• Use tools. Google Keyword Planner, Ubersuggest, and Serpstat can help you find variations and show search volume.

• Add qualifiers. City, price, product type, format—all of this makes the query more specific.

• Check the competition. Some words are too expensive or too broad. It’s not always worth fighting for them.

What are Negative Keywords?

These are words for which you don’t want your ads to show. For instance, if you sell courses rather than giving them away for free, then “free” should be added to your negative keyword list. This helps eliminate irrelevant clicks and saves your budget.

Negative keywords act as a filter, cutting off irrelevant audiences. The better you define them, the more effective your campaign will be.

How to Check Keyword Effectiveness After Launch

Once your ads are live, don’t stop there. Check your reports in Google Ads. Pay attention to:

• CTR (Click-Through Rate): Indicates how attractive your ad is.

• CPC (Cost Per Click): How much you pay for each visit.

• Conversions: Are these clicks leading to actual results?

Don’t hesitate to adjust your keyword list: remove ineffective ones, add new ones, and incorporate negative keywords as data comes in.

Common Keyword Selection Mistakes

Keyword selection is the foundation of a successful PPC campaign, but beginners often make mistakes that reduce its effectiveness. For example, many choose keywords that are too broad, which can bring a lot of traffic, but this traffic is often irrelevant and doesn’t convert into customers. Another common problem is ignoring user intent: if someone is just looking for information and you immediately try to sell them something, they’ll likely leave your site.

Equally important is the absence of negative keywords—without them, ads are shown to a broad audience, including those you don’t need, which simply wastes your budget. Some beginners also focus on “trendy” or popular keywords that seem appealing but, in practice, turn out to be expensive and don’t deliver results for their specific business due to high competition or audience mismatch.

Several other common blunders include ignoring local context (if you don’t consider your audience’s geography, ads might show to people who can’t physically use your services) and overlooking synonyms and phrase variations (this narrows your reach and loses potential customers who search for the same thing using different words). Finally, some don’t check for keyword seasonality: spending budget on keywords that are only relevant during specific periods, without considering the timing, is another way to waste money. By avoiding these mistakes, you can make your campaign more precise and effective.

Keyword Selection is Analytics, Not Intuition

Successful PPC advertising isn’t about chance; it’s about precision. And it starts not in the Google Ads dashboard, but with careful work on the queries that will lead customers to you. If you pick keywords by guesswork, the results will be unpredictable. However, if you approach keyword selection as an analytical process, you’ll achieve stable metrics that can be scaled.

Keywords are like a GPS navigator in the advertising system. They point exactly where your customer needs to go. A wrong address, and the user gets lost, and your money is wasted. But if the route is precise, conversion becomes a reality. Even the best ad won’t save the day if it’s shown to the wrong people. So, don’t cut corners on this step: analyze, refine, and test. The results will follow.
