Without the right keywords, no ad will work. The success of any PPC campaign depends not only on budget or creative but on showing ads to the right people. You could pay for clicks that never convert into leads, orders, or subscriptions.

Keywords are the bridge between your site and users. It’s at the keyword selection stage that budgets often ‘leak’. In this article, we’ll show you how to choose queries that actually work.

What are keywords in PPC advertising

These are the phrases users type into search engines—which Google uses to decide which ads to show. For example, if someone searches “buy car lamp,” your site might appear—only if that keyword is in your campaign settings.

But crucially: you shouldn’t show for everything similar-sounding—only for terms that truly match your goal. That’s your ‘right’ keyword.

Keyword types

Generally, they fall into three categories:

• Broad: “laptop,” “training,” “lamp” — very competitive, poorly filters audience.
• Mid‑frequency: “laptop for students,” “marketing training” — more targeted.
• Exact (low frequency): “buy HP laptop with backlit keyboard” — fewer impressions but precise targeting.

Ideally, combine these types to reach the right audience at different stages of their journey.

How to gather keywords: step by step

1. Start with yourself. Imagine how you’d search for your product or service. List those queries.
2. Look in Google. Type those words into search and note autocomplete suggestions — these are popular phrases.
3. Use tools. Google Keyword Planner, Ubersuggest, Serpstat help you find variants and show search volumes.
4. Add qualifiers. City, price, product type, format — all make your query more precise.
5. Check competition. Some terms are too expensive or broad. It’s not always worth bidding on them.

What are negative keywords

These are terms you don’t want to show for. For example, if you sell courses rather than give them away free, add “free” to your negative list. This filters out irrelevant clicks and saves budget.

Negative keywords act as a filter to exclude non‑relevant traffic. The better you define them, the more efficient your campaign.

How to check keyword performance post-launch

Launched ads — don’t stop there. Review your Google Ads reports. Pay attention to:

• CTR (click‑through rate): how engaging the ad is.
• CPC (cost per click): how much you pay per click.
• Conversions: whether clicks lead to desired actions.

Common keyword mistakes

Keyword research is the foundation of a successful PPC campaign, but beginners often make errors that hurt performance. For example, choosing overly broad terms can drive traffic but not quality leads. Another frequent issue is ignoring user intent: if someone seeks information and you immediately push a sale, they’ll likely bounce.

Equally critical is neglecting negative keywords — without them you waste budget on irrelevant audiences. Some novices chase trendy or popular terms that prove too expensive or misaligned with their business due to competition or audience mismatch.

Other pitfalls include ignoring local context (ads shown to people who can’t access your service), forgetting synonyms and phrase variations (narrow reach), and overlooking seasonality (spending on terms irrelevant in the current period). Avoiding these mistakes makes your campaign far more precise and effective.

Keyword research is analytics, not guesswork

Successful PPC isn’t about luck but precision. It starts not in the Google Ads interface but with careful keyword research. Choosing keywords “by eye” yields unpredictable results; an analytical approach delivers stable, scalable metrics.

Keywords are like a GPS in advertising: they guide users to you. The wrong address and users get lost, wasting budget. The right route turns clicks into conversions. Even the best ad won’t save a campaign if it isn’t shown to the right people. So invest in this phase: analyze, refine, test. Results will follow.
