You drive better results from Google Ads when you choose the right keywords. Google Ads keyword research helps you understand what people search for, how often they search, and how competitive each term is within SEM and PPC campaigns. When you align those searches with your offer, you attract higher‑intent traffic and reduce wasted spend.
To do keyword research for Google Ads, define your campaign goal, generate relevant keyword ideas with tools like Keyword Planner, analyse search volume and cost data, and refine your list using match types and negative keywords to control intent and budget. This process turns broad ideas into focused, high‑performing search terms that support profitable Google Ads campaigns.
When you approach keyword research with a clear strategy, you gain control over targeting, structure, and optimisation. The rest of this guide shows you how to build, evaluate, and organise keywords so your PPC keyword research supports measurable growth.
Key Takeaways
- Align your keyword research with clear campaign goals and user intent.
- Use data to filter, prioritise, and control spend with match types and negatives.
- Structure and refine your keywords to improve performance over time.
Establishing Campaign Goals and Strategy
Strong keyword research starts with a defined campaign goal, measurable targets, and a clear understanding of your audience’s search intent. When you align objectives, keywords, and landing pages, you improve conversion rate and protect your ROI.
Setting Clear Objectives
You need a specific campaign goal before you select a single keyword in Google Ads. Vague aims such as “get more traffic” weaken decision-making and waste budget.
Define what success looks like in measurable terms. For example:
- Lead generation: target cost per lead and conversion rate
- Sales: target return on ad spend and overall ROI
- Brand awareness: impression share and reach
Tie each objective to a meaningful business outcome. If you sell high-margin products, you may accept a higher cost per click to capture strong purchase intent.
Document your targets clearly. When you review search terms or adjust bids, you will judge performance against these figures, not assumptions.
Translating Objectives Into Keyword Strategy
Once you define your objective, translate it directly into keyword selection criteria. Your campaign goal determines the level of commercial intent you should prioritise.
If you aim to drive online sales, focus on keywords with clear purchase intent, such as:
- “buy accounting software”
- “accounting software price UK”
- “best accounting software for small business”
These terms signal readiness to act, not just research. They often produce higher conversion rates, even if volume is lower.
If you focus on lead generation, target keywords that reflect problem awareness and solution comparison. Support them with tightly matched ad copy and a relevant landing page that reinforces the search intent.
Avoid mixing conflicting intents within the same ad group. When objectives and keywords align, your Quality Score improves and your ROI becomes easier to scale.
Aligning Keywords With Target Audience
Effective keyword research reflects how your target audience actually searches. You must understand their priorities, budget level, and decision stage.
Map keywords to search intent categories:
| Search Intent | Example Keyword | Suitable Landing Page |
|---|---|---|
| Informational | “how to reduce payroll errors” | Educational guide or blog article |
| Commercial | “best payroll software UK” | Comparison or feature page |
| Transactional | “buy payroll software online” | Product or pricing page |
Match each keyword group to a landing page built for that intent. A transactional keyword should never send users to a generic homepage.
When you align keywords with audience needs and landing page content, you increase relevance. That relevance supports stronger conversion rates and more predictable ROI within your Google Ads campaigns.
Generating and Expanding Keyword Ideas
Effective keyword research starts with structured thinking and expands through data. You begin with clear seed keywords, use reliable keyword research tools to discover new keywords, and validate ideas through competitor analysis.
Brainstorming Seed Keywords
Start with your core products or services and write down direct, literal terms a customer would search. These are your seed keywords, such as “emergency plumber London” or “accounting software for small business”.
Use your website as a reference point. Review page titles, service descriptions, FAQs, and category names to extract precise phrases that reflect buying intent.
Group your seed keywords into themes:
- Service-based terms (e.g. boiler repair, tax return filing)
- Location modifiers (e.g. Manchester, near me, UK)
- Intent qualifiers (e.g. cost, quote, hire, buy)
Avoid broad, unfocused words such as “plumber” unless your budget supports large volumes. Specific phrases typically align better with commercial intent.
Store everything in a spreadsheet from the start. Create columns for keyword, intent, landing page, and notes. This structure makes expansion and filtering easier later.
Discovering New Keywords Using Tools
After defining seed keywords, use a keyword tool to expand them with real search data. Google Keyword Planner remains the primary option for Google Ads because it provides search volume estimates, forecasts, and suggested bid ranges.
Enter your seed keywords or start with a website URL to generate keyword ideas. Filter by:
- Location
- Language
- Average monthly searches
- Competition level
Look for variations that show clear intent, such as “same day boiler repair” instead of “boiler”. These often convert better.
Use additional keyword research tools such as Ahrefs or SEMrush to identify longer-tail queries and related questions. Export relevant ideas into your spreadsheet and remove duplicates. Focus on relevance first, then volume.
Analysing Competitor Keywords
Competitor analysis helps you identify gaps and opportunities. Start by searching your main keywords in Google and noting which advertisers appear consistently in paid results.
Use tools like Ahrefs or SEMrush to review competitor keywords driving paid traffic. Pay attention to:
- High-intent commercial terms
- Branded vs non-branded keywords
- Landing pages tied to specific ads
Do not copy competitor keywords blindly. Instead, assess whether each term matches your offer, pricing, and location.
Add promising competitor keywords to your spreadsheet and label them clearly. This keeps your strategy organised and allows you to test them in controlled ad groups rather than mixing them with unrelated terms.
Evaluating and Filtering Keywords
You need to narrow your keyword list using measurable data, not instinct. Focus on search volume, competition, and real performance signals so you invest budget in terms that can generate qualified traffic and conversions.
Assessing Search Volume and Trends
Start with avg. monthly searches in Keyword Planner. This metric shows how often people search a term and gives you a baseline for potential traffic.
Treat broad search volume ranges with caution. A keyword showing 1K–10K monthly searches provides less certainty than one with a tighter range, especially when forecasting spend and clicks.
Balance volume with relevance. High monthly searches can attract more impressions, but they often bring broader search queries and weaker intent.
Review trends over time. If search volume drops seasonally, adjust bids and budgets accordingly.
Use Search Console to compare Google Ads data with organic search queries. This helps you confirm whether interest is consistent and whether your audience uses specific variations you may have missed.
Prioritise keywords with steady demand and clear relevance to your offer.
Understanding Keyword Difficulty and Competition
Keyword difficulty in paid search centres on advertiser competition and expected cost per click. In Keyword Planner, review the competition column and top-of-page bid estimates to gauge pressure.
High competition usually means higher costs and lower initial ad impression share unless your bids and Quality Score remain strong.
Your Quality Score directly affects how competitive you can be. Google evaluates expected click-through rate, ad relevance, and landing page experience. Strong alignment between keyword, ad copy, and landing page reduces costs and improves position.
Monitor ad impression share after launch. If impression share remains low due to rank, refine ad relevance or increase bids. If you lose share due to budget, reassess keyword priorities.
Avoid automatically discarding competitive terms. Instead, assess whether projected conversion value justifies the cost.
Selecting Keywords by Intent and Performance
Search intent determines whether traffic converts. Separate your keyword list into clear groups:
- High-intent transactional (e.g. “buy”, “quote”, “near me”)
- Commercial research (e.g. “best”, “compare”, “reviews”)
- Informational (e.g. “how to”, “what is”)
Prioritise terms that match your campaign objective. If you want leads or sales, focus on transactional and commercial search queries.
After launch, analyse the Search Terms report. This report shows the actual search terms triggering your ads and reveals mismatches between planned keywords and real behaviour.
Evaluate keyword performance using metrics such as click-through rate, conversion rate, cost per conversion, and return on ad spend. Pause low-performing keywords and add irrelevant search terms as negatives.
Refine continuously. Effective filtering depends on ongoing review, not a one-time selection process.
Keyword Match Types and Negative Keywords
Keyword match types control how closely a user’s search must match your keyword before your ad can show. Negative keywords filter out unwanted searches so you protect budget and improve relevance.
Choosing the Right Match Types
Google Ads offers three primary keyword match types: broad match, phrase match, and exact match. Each one changes how widely your ads can appear.
- Broad match reaches the widest audience. Your ad may show for related searches, including synonyms and variations. This helps you discover new queries, especially when you want to get search volume and forecasts quickly. However, it can attract irrelevant traffic if you do not monitor it closely.
- Phrase match shows your ad when the search includes the meaning of your keyword in the correct order. It balances control and reach.
- Exact match limits your ad to searches with the same meaning or intent as your keyword. It offers the most control over relevance and spend.
Structure match types within tightly themed ad groups. For high-intent terms, prioritise exact match. For discovery, test broad match with smart bidding and review performance frequently.
Implementing Negative Keyword Lists
Negative keywords stop your ads from showing on searches that do not fit your offer. They prevent wasted clicks and protect your budget.
You can add negative keywords at campaign or ad group level. Use ad group negatives to separate closely related themes. Use campaign-level exclusions to block irrelevant topics across the entire account.
Negative keyword match types behave differently from positive keywords. For example:
- Negative broad match blocks searches containing all the negative terms, regardless of order.
- Negative phrase match blocks searches that include the exact phrase.
- Negative exact match blocks only that specific query.
Negative keywords do not expand to close variants in the same way as positive keywords. Build and maintain shared negative keyword lists for recurring exclusions such as “free”, “jobs”, or “DIY” if you sell paid services.
Review and update these lists regularly as your campaigns grow.
Refining Keywords With Search Term Reports
Your search terms report shows the actual queries users typed before clicking your ad. Use it to validate your keyword match types and uncover gaps.
Look for three patterns:
- Queries converting well that are not yet in your account. Add them as exact match keywords.
- Irrelevant searches that triggered broad or phrase match keywords. Add these as negative keywords.
- High-impression, low-conversion terms that may need tighter match types.
Segment data by ad groups to see which themes attract poor-quality traffic. When you spot consistent waste, exclude keywords at the right level or move high-performing terms into more restrictive match types.
Make reviewing search terms a routine task. Frequent refinement keeps your targeting aligned with user intent and improves cost control.
Structuring Ad Groups and Optimising For Performance
A clear Google Ads account structure improves ad relevance, Quality Score, and cost control. When you group keywords tightly and align ads with the right landing page, you increase ad impression share and reduce wasted spend.
Grouping Keywords for Relevant Ad Groups
Organise your keywords into tightly themed ad groups within each of your Google Ads campaigns. Avoid single-keyword ad groups unless you need strict control over bids or messaging. Instead, group closely related terms that share the same intent, such as “emergency plumber London” and “24 hour plumber London”.
Use a spreadsheet to cluster keywords by:
- Search intent
- Product or service category
- Location or audience segment
- Match type
Each ad group should focus on one clear theme. This allows you to write specific ad copy and set appropriate max CPC bids based on expected value and competition.
Review top of page bid estimates and bid ranges to guide your initial bidding strategy. If you mix high- and low-intent keywords in one ad group, Smart Bidding or manual bidding will optimise towards blended signals, which can reduce efficiency and increase average cost per click.
Tightly structured ad groups support higher Quality Score, which can lower CPC and improve ad impression share.
Aligning Ads and Landing Pages
Write ad copy that directly reflects the keywords in each ad group. Include the primary keyword in the headline and reinforce it in the description to strengthen ad relevance.
For example, if the ad group targets “boiler repair Manchester”, your:
- Headline should reference boiler repair in Manchester.
- Description should mention response time, pricing, or guarantees.
- Display path should reinforce the service.
Send traffic to a dedicated landing page that matches the ad’s promise. Do not direct all traffic to a generic homepage. A focused landing page improves landing page experience, supports higher Quality Score, and can reduce cost per click.
Ensure message consistency across keyword, ad copy, and landing page content. When these elements align, you improve conversion rate while maintaining tighter control over bids and overall campaign performance.
Leveraging Advanced Tools and Integration With SEO
You strengthen Google Ads performance when you combine Google Keyword Planner with external keyword tools and real organic data. Aligning paid and organic search insights helps you prioritise intent, control costs, and build tighter keyword plans.
Comparing Google Keyword Planner With External Keyword Tools
Google Keyword Planner sits inside Google Ads and pulls data directly from Google. It shows average monthly searches, competition levels, and bid estimates, which makes it essential for budgeting and forecasting within a keyword plan.
However, Keyword Planner groups close variants and often provides search volume ranges unless you run active campaigns. It also focuses on paid metrics rather than organic difficulty or competitor rankings.
External keyword tools such as SEMrush and Ahrefs expand your view. They show:
- Estimated organic traffic and keyword difficulty
- Competitor keyword gaps
- Historical ranking data
- Paid search insights from rival advertisers
Use Keyword Planner to validate cost and intent. Use SEMrush or Ahrefs for deeper competitor analysis and to identify gaps your competitors target in both paid and organic search.
Integrating Organic and Paid Keyword Strategies
You improve efficiency when you treat SEO and Google Ads as connected channels rather than separate efforts. Start by reviewing Google Search Console data to identify queries that already drive impressions or clicks in organic search.
If you rank on page one for a high-intent term, test whether paid ads increase total click share or simply replace organic clicks. For keywords where you rank poorly but see strong impressions, consider supporting them with paid campaigns.
Pay close attention to:
- Branded keywords that protect your brand from competitors
- High-converting non-branded terms discovered in Google Ads search term reports
- Informational queries suited for SEO rather than paid traffic
Align landing pages, messaging, and match types with your organic strategy to keep intent consistent across channels.
Exporting and Managing Keyword Lists
Keyword research becomes actionable when you organise it clearly. Export data from Google Keyword Planner, SEMrush, or Ahrefs into a spreadsheet to filter and categorise terms by intent, funnel stage, and estimated cost per click.
Create columns for:
- Keyword
- Match type
- Search volume
- Estimated CPC
- Competition level
- Target landing page
Group keywords into tightly themed ad groups before uploading them into Google Ads. Maintain a master spreadsheet so you can update performance metrics over time and refine bids, pause underperforming terms, and expand high-performing clusters based on real data.
Conclusion
You build profitable Google Ads campaigns when you treat keyword research as an ongoing process, not a one-off task. You choose terms based on intent, structure them carefully, and refine them with real data.
Focus on the fundamentals:
- Use Keyword Planner to generate ideas and review forecasts.
- Start with phrase and exact match for control.
- Review the Search Terms report to promote winners and block waste.
- Add negative keywords to protect your budget.
- Update regularly using trends and performance data.
You improve results when you align keywords with clear ad groups and relevant landing pages. That structure supports stronger Quality Scores and more efficient spend.
Use automation with care. Broad match and Smart Bidding work best when you feed the platform accurate conversion tracking and reliable first‑party data.
