Keyword research is the foundation of a successful Google Search Ads campaign. Choosing the right keywords ensures your ads reach the right audience, drive more leads, and maximise your return on investment. Without proper keyword research, you risk wasting budget on irrelevant traffic that fails to convert.
In this guide, we will break down the keyword research process step by step, helping business owners generate more leads effectively.
What is Keyword Research?
Keyword research is the process of identifying and analysing the search terms people use on Google to find products or services. For Google Search Ads, keyword research allows advertisers to bid on relevant terms that drive potential customers to their website.
Effective keyword research involves:
- Understanding your audience’s search intent
- Finding high-performing keywords
- Evaluating competition and cost-per-click (CPC)
- Grouping keywords into relevant ad groups
Why is Keyword Research Important for Google Search Ads?
Choosing the right keywords ensures your ads appear in front of the right audience at the right time. Here’s why keyword research is crucial:
- Higher conversion rates:Â Targeting relevant keywords increases the chances of attracting ready-to-buy customers.
- Cost-efficiency:Â Prevents wasted ad spend on irrelevant searches.
- Better ad performance:Â Improves Quality Score, which can lower CPC and increase ad visibility.
- Competitive advantage:Â Helps you identify gaps and opportunities within your industry.
Step-by-Step Guide to Conducting Keyword Research
1. Define Your Goals and Audience
Before you start researching keywords, clarify your objectives:
- Are you looking to generate leads, increase sales, or drive traffic?
- Who is your ideal customer?
- What problems do they need solving?
Understanding your audience’s pain points and motivations will help you select keywords that align with their intent.
2. Brainstorm Seed Keywords
Seed keywords are the foundation of your research. These are the broad terms that describe your business, products, or services.
For example, if you own a digital marketing agency, some seed keywords might include:
- Digital marketing services
- Google Ads agency
- PPC advertising
Think of terms potential customers might type into Google when searching for a business like yours.
3. Use Keyword Research Tools
Leverage keyword research tools to expand your keyword list and analyse search volume, competition, and CPC. Some powerful tools include:
- Google Keyword Planner (free) – Provides keyword ideas, search volume, and bid estimates.
- SEMrush – Offers competitive keyword analysis and insights.
- Ahrefs – Displays keyword difficulty, click potential, and competitor data.
- Ubersuggest – Generates keyword suggestions and SEO metrics.
Use these tools to identify high-intent keywords that align with your goals.
4. Analyse Search Intent
Not all keywords are created equal. Google categorises search intent into four types:
- Informational:Â Users seeking knowledge (e.g., “how to do keyword research”)
- Navigational:Â Users searching for a specific brand or website (e.g., “Google Ads login”)
- Commercial:Â Users researching products before making a decision (e.g., “best PPC agency for small businesses”)
- Transactional:Â Users ready to take action (e.g., “hire Google Ads expert”)
For lead generation campaigns, focus on commercial and transactional keywords, as they attract users with purchase intent.
5. Evaluate Keyword Metrics
Assess each keyword’s potential based on:
- Search volume:Â The number of times a keyword is searched monthly.
- Competition level:Â Indicates how difficult it is to rank for a keyword.
- CPC (cost per click):Â The estimated cost of running ads on that keyword.
- Click-through rate (CTR):Â Measures how often users click on ads for that keyword.
Balancing search volume and competition will help you select cost-effective keywords.
6. Organise Keywords into Ad Groups
Grouping keywords into tightly themed ad groups improves relevance and ad performance. For example:
Ad Group: Google Ads Services
- Google Ads agency
- PPC management services
- Google Ads consultant
Ad Group: Local SEO Services
- Local SEO expert
- Best SEO company near me
- Small business SEO services
Each ad group should have its own tailored ad copy and landing page for better conversions.
7. Identify Negative Keywords
Negative keywords prevent your ads from showing for irrelevant searches, saving budget and improving ROI.
For example, if you offer premium marketing services, you might exclude keywords like:
- Free Google Ads course
- Cheap PPC management
- DIY Google Ads
Regularly update your negative keyword list to filter out unqualified traffic.
8. Monitor and Optimise
Keyword research doesn’t stop after launching your campaign. Regularly review performance metrics and refine your keyword strategy by:
- Removing underperforming keywords
- Adding new high-converting keywords
- Adjusting bids based on conversion data
- Updating negative keywords to improve targeting
Common Keyword Research Mistakes to Avoid
1. Ignoring Long-Tail Keywords
Long-tail keywords (e.g., “Google Ads agency for dentists”) have lower search volume but higher conversion rates because they are more specific.
2. Relying Only on Broad Match Keywords
Broad match can lead to irrelevant traffic. Instead, use a mix of:
- Exact match:Â [Google Ads consultant]
- Phrase match:Â “Google Ads consultant for startups”
- Broad match modifier:Â +Google +Ads +consultant
3. Not Considering Local Keywords
If you offer location-based services, include geo-specific keywords like “Google Ads agency in London.”
4. Overlooking Competitor Research
Analyse competitor keywords using tools like SEMrush or Ahrefs to discover high-performing terms you might be missing.
Effective keyword research is essential for running profitable Google Search Ads. By selecting the right keywords, understanding search intent, and continuously optimising your campaign, you can generate more leads and maximise your advertising budget.
