How to do keyword research for blog posts

What is Keyword Research?

At its simplest level, keyword research is the process of discovering the specific words, phrases, and questions people type into search engines (like Google) to find information, products, or services.

However, for a high-level SEO strategy, it’s much more than just a list of words. It is market research for the 21st century. It allows you to peer into the “collective subconscious” of your target audience to understand their pain points, their vocabulary, and their stage in the buying journey.

That is a fantastic way to frame the process. In the world of design thinking and high-level strategy, this is often called the “Double Diamond” approach. By using this framework, you show your readers that SEO isn’t just about plugging words into a tool; it’s a creative and analytical discipline.

To reach that high word count, you can position this section as the “The Methodology of Discovery.” Here is an intro to that section:

The Keyword Research Process: Expansion and Refinement

To find the “golden” keywords that will actually drive revenue for your business, you must move through a two-phase cycle: Divergent Thinking and Convergent Thinking.

Many amateur bloggers make the mistake of jumping straight to a keyword tool, typing in one idea, and picking the first five results they see. This leads to generic content that gets buried by larger competitors. To create a 9,000-word authority piece, you must instead treat your research like an funnel.

Phase 1: Divergence (The Creative Explosion)

The goal of the divergence phase is quantity over quality. At this stage, you are “going out”—opening the floodgates to capture every possible way a potential customer might describe their problem. You aren’t judging the ideas yet; you are simply gathering the raw materials.

During this phase, you should look beyond just SEO tools and tap into:

Internal Brainstorming: What are the literal terms you use to describe your service?
Customer Feedback: How do your clients in Limerick actually describe their struggles in meetings or emails? (Often, they don’t use “SEO jargon.”)
Existing Data: What are you already accidentally ranking for in Google Search Console?
Social Listening: What questions are being asked on Reddit, Quora, or industry-specific forums?

Phase 2: Convergence (The Strategic Filter)

Once you have a massive “universe” of potential keywords, you must “come back in.” This is the Convergent Phase, where you apply cold, hard data to your creative list. You cannot target 500 keywords in one post, so you must use specific filters to find the ones that will offer the best Return on Investment (ROI).

You will filter your “messy” list through three critical lenses:

Search Volume: Is anyone actually looking for this?
Keyword Difficulty (KD): Do we have the “ranking power” to beat the current top 10?
Search Intent: Does this keyword lead to a person who wants to learn, or a person who wants to buy?

Tools To Help You Create Your Diamond

To navigate the expansion and refinement of your keyword list, you need a mix of tools. Some are designed to help you diverge (find new ideas), while others are built to help you converge (analyze the data).

Here is a breakdown of the best tools for each stage of the process as of 2026.

1. Tools for the Divergent Phase (Idea Generation)

In this stage, your goal is to find as many variations and “human” questions as possible.

AnswerThePublic: This tool is the “king” of the divergent phase. It scrapes Google’s autocomplete data and visualizes it as a “cloud” of questions (Who, What, Why, Where). It’s perfect for finding the long-form subheadings that will help you reach a high word count.
AlsoAsked: Similar to AnswerThePublic, this tool focuses specifically on “People Also Ask” data. It shows you the hierarchy of questions users ask after their initial search, helping you map out a logical flow for a 4,000+ word post.
Google Search Console (GSC): This is often overlooked for research. Look at the “Queries” report to find “accidental keywords”—terms you are already ranking for on page 2 or 3 that you haven’t intentionally optimized for yet.
Reddit & Quora: Use these to find the exact language and slang your audience uses. If you find a recurring question on a subreddit like r/Limerick, you’ve found a keyword with high-intent but often low competition in traditional tools.

2. Tools for the Convergent Phase (Data & Filtering)

Once you have your “messy” list, you need these tools to tell you which keywords are worth your time.

Ahrefs or Semrush: These are the “industry standards.” They provide the most accurate Keyword Difficulty (KD) scores and Search Volume estimates. Use these to trim your list by removing keywords that are too difficult for your site’s current authority.
Google Keyword Planner: Since the data comes directly from Google, it is highly reliable for volume trends. It’s also completely free, though it’s technically designed for advertisers (PPC), so the “Competition” metric refers to ad spend, not organic SEO difficulty.
LowFruits: A newer favorite for niche bloggers. It helps you quickly identify keywords where “weak” websites (like forums or low-authority blogs) are ranking on Page 1, signaling an easy opportunity for you to swoop in.

3. All-in-One & AI-Driven Tools

Ubersuggest: A great “middle ground” tool that offers a bit of everything (ideas and data) at a more affordable price point for small businesses.
Surfer SEO / Clearscope: These aren’t just for research; they are for Content Optimization. Once you have your keywords, these tools tell you exactly how many times to use them to compete with the 9,000-word giants currently ranking.

Tool	Phase	Best Feature	Price Level
AnswerThePublic	Divergent	Visualizing “Question” keywords	Free / Paid
Google GSC	Divergent	Finding “Hidden” opportunities	Free
Ahrefs	Convergent	Deep Competitor & Backlink data	Premium
LowFruits	Convergent	Spotting “Weak” competition	Pay-as-you-go
Google Trends	Both	Seeing if a topic is growing or dying	Free

To write a definitive guide that hits those 4,000–9,000 words, you need to break Step 1: The Brainstorming (Divergent) Phase into multiple sub-layers.

This isn’t just about “thinking of words”; it’s about extracting data from your business, your customers, and your competitors to create a massive list of “Seed Keywords.”

Step 1: Brainstorming & The Art of the Seed Keyword

Before you ever touch a paid tool like Ahrefs or Semrush, you must begin with Seed Keywords. These are broad, 1–2 word phrases that define your niche. Think of them as the “roots” of your content tree; they won’t be your final targets, but every long-tail keyword you eventually find will grow from them.

1.1 Internal Discovery: Thinking Like Your Business

Start by looking inward. You are an expert in your field—don’t let the tools tell you what you do.

The Service List: List every primary service you offer. If you’re a plumber in Limerick, your seeds are “boiler repair,” “blocked drains,” “emergency plumbing,” and “bathroom installation.”
The “Jargon” Audit: What do you call your services versus what your customers call them? (e.g., You might call it “Search Engine Optimization,” but a client might ask for “getting on the first page of Google.”) Both are vital seeds.
Website Menu Mining: Look at your existing site navigation. Your categories are usually your most important seed keywords.

1.2 External Discovery: Listening to the Customer

This is where you find the “human” side of SEO. This data is often more valuable than tool data because it reflects real-world pain points.

Customer Feedback & Reviews: Read your Google Business Profile reviews. What specific words do customers use to praise you? Phrases like “fixed my leak on a Sunday” or “affordable SEO for small business” are goldmines.
Sales & Support Emails: Go through your “Sent” folder. What questions are you answering over and over again? Every “How do I…” or “Why does…” email is a potential blog post title.
Social Listening: Spend 20 minutes on Reddit (e.g., r/Limerick or r/SEO) or Quora. Look for people complaining about your industry. Their complaints are your keyword opportunities.

1.3 Competitor “Borrowing”

You don’t need to reinvent the wheel. Your competitors have already done some of the work for you.

The Homepage Scan: Visit the websites of the top 3 agencies in Limerick. What are their main headings? What topics do they blog about most frequently?
Category Pages: Look at their blog categories. If a competitor has a whole section dedicated to “Local SEO Tips,” you know that “Local SEO” is a seed keyword worth investigating.

1.4 The “Alphabet Soup” Method (Free & Easy)

Go to Google and type in one of your broad seed keywords (e.g., “SEO for…”).

Google Autocomplete: Type your keyword + “a”, then “b”, then “c”. Google will show you exactly what people in Ireland are searching for in real-time.
People Also Ask (PAA): Look at the questions box in the search results. These are literally the “seeds” of your subheadings

Step 2: The Convergent Phase (Filtering for Gold)

Now that you have 100+ ideas on a spreadsheet, it’s time to be ruthless. You can’t write about everything, and even in a 9,000-word guide, you need a “North Star” keyword to guide the structure.

To filter your list, we use the “Three-Lens Framework.”

1. The Lens of Search Volume: “Is Anyone There?”

Search volume tells you the average number of times a keyword is searched per month.

The Trap: Many people only look for keywords with thousands of searches.
The Strategy: For a local Limerick business, a keyword with a volume of 50 searches a month might be worth more than a global term with 5,000. Why? Because those 50 people are likely in your city and ready to hire you.
Pro Tip: In a long-form blog post, you aren’t just targeting one “head term” (high volume). You are aiming to rank for dozens of “long-tail” variations (low volume) that add up to a massive amount of traffic.

2. The Lens of Keyword Difficulty (KD): “Can I Win?”

KD is a score (usually 0–100) that tells you how hard it is to rank on Page 1.

0–15 (Very Easy): “Low-hanging fruit.” You can often rank for these just by writing a good, well-structured paragraph.
16–40 (Easy/Medium): Requires a dedicated, high-quality blog post (like the one you’re writing!) and perhaps a few internal links.
40+ (Hard): Usually requires a high-authority domain and a significant number of external backlinks.
The Strategy: If your website is new, ignore anything with a KD over 30 for now. Build your “authority” on the easy wins first.

3. The Lens of Search Intent: “What Do They Want?”

This is the most important filter. If you get the intent wrong, your blog will be useless. Google categorizes intent into four buckets:

Intent Type	What the User Wants	Example Keyword	Best Content Type
Informational	To learn something	“What is SEO?”	Blog Post / Guide
Navigational	To find a specific site	“Limerick SEO Engine login”	Homepage
Commercial	To compare options	“Best SEO agencies Limerick”	Listicles / Reviews
Transactional	To buy/hire right now	“Hire SEO expert Limerick”	Service / Sales Page

Critical Rule: If the top 10 results for a keyword are all “Service Pages” and you try to rank with a “Blog Post,” you will likely fail. Google has already decided that the user wants to buy, not read.

To build a truly authoritative guide on keyword research, Step 3 must move from a simple list of words to a Topical Map.

In this section of your blog, you’ll explain how to organize keywords into clusters. This structure ensures you cover every angle of a topic, which signals to Google that you are a “Topical Authority” in the Limerick market.

Step 3: Organizing Keywords into Clusters (Building Your Topical Map)

Once you have a filtered list of high-value keywords, the biggest mistake you can make is trying to target them one by one in isolated, short posts. Instead, modern SEO requires Keyword Clustering.

This is the process of grouping related keywords together to create a “Topical Map.” This map acts as the blueprint for your content, ensuring you provide a comprehensive answer to every possible question a user might have.

3.1 The Pillar and Cluster Model

Think of your content architecture like a hub-and-spoke system:

The Pillar (The Hub): A broad, comprehensive page that covers a major topic in detail (e.g., “The Complete Guide to SEO for Limerick Businesses”).
The Clusters (The Spokes): More specific, detailed articles that dive deep into “sub-topics” (e.g., “How to Optimize a Google Business Profile in Limerick”).

3.2 How to Group Your Keywords

To organize your list effectively, group your keywords based on two main criteria:

Semantic Relevance: Group words that are conceptually related. For example, “keyword difficulty,” “KD score,” and “competitive analysis” all belong in the same cluster because they are part of the same “conversation.”
SERP Overlap: This is a professional-grade tip. Type two different keywords into Google. If the results on Page 1 are almost identical, Google considers them the same “topic.” You should cluster these into one single section rather than writing two separate pieces.

3.3 Mapping Keywords to Content

Once grouped, you should assign each cluster a role in your content plan:

Primary Keyword: The main term with the best balance of volume and intent. This becomes your H2 heading.
Secondary Keywords: Variations and synonyms that you sprinkle throughout the body text to help search engines understand the context.
Supporting Questions: These are often “Long-tail” keywords (found in the “People Also Ask” section) that become your H3 subheadings.

The Benefits of This Approach

By organizing your research into clusters, you achieve three things that standalone posts cannot:

Eliminate Keyword Cannibalization: You ensure two pages aren’t fighting for the same search term.
Boost Topical Authority: By covering every sub-topic, Google starts to view your site as the definitive resource for that niche.
Improve User Experience: Clusters create a logical journey for the reader, allowing them to start with a broad overview and click through to deep-dives as needed.

Expert Insight: For a local business, clustering is your secret weapon. You might have a cluster dedicated entirely to “Limerick SEO Trends,” which positions you as the local expert in a way a national agency never could.

Mapping Intent to the Customer Journey (The Funnel)

To master keyword research, you must understand where your customer stands in their decision-making process. We visualize this using a Marketing Funnel. Your goal is to create content that “meets” the customer at every stage, guiding them from curiosity to conversion.

1. Top of the Funnel (TOFU): Awareness

At this stage, the user is experiencing a “symptom” but doesn’t necessarily know the solution yet. They are looking for information and education.

Intent Type: Informational.
The Query: “Why is my website traffic dropping?” or “How does Google work?”
The Strategy: Use these keywords for educational blog posts. Don’t try to sell here; instead, establish yourself as a helpful authority in the Limerick business community.

2. Middle of the Funnel (MOFU): Consideration

Now, the user has defined their problem and is researching different ways to solve it. They are comparing strategies, tools, or types of services.

Intent Type: Commercial Investigation.
The Query: “SEO vs. Google Ads” or “Best SEO agencies in Ireland reviews.”
The Strategy: Create comparison guides, “Best of” lists, or case studies. This is where you show why your specific approach to SEO is the most effective.

3. Bottom of the Funnel (BOFU): Conversion

This is the “money” stage. The user has decided on a solution and is looking for the right person or company to provide it. They are ready to take action.

Intent Type: Transactional.
The Query: “SEO consultant Limerick” or “Hire SEO agency near me.”
The Strategy: These keywords should lead to your Service Pages, Contact Pages, or “Request a Quote” forms. The content here should be concise, persuasive, and focused on your Unique Selling Proposition (USP).

The “Full-Funnel” Advantage

Most businesses only focus on the Bottom of the Funnel because those keywords seem the most “valuable.” However, by only targeting transactional terms, they miss out on the opportunity to build trust early on.

Why this matters for your blog: If you only write for people ready to buy today, you are competing in a very expensive and crowded space. By using keyword research to find TOFU and MOFU queries, you “befriend” the customer while they are still learning. By the time they reach the bottom of the funnel, you are already their trusted expert.

Visualizing the Journey

Funnel Stage	Customer Mindset	Content Type	Example Keyword
Awareness	“I have a problem.”	Educational Blog	“What is local SEO?”
Consideration	“What are my options?”	Comparison Guide	“SEO vs Social Media Marketing”
Conversion	“I’m ready to buy.”	Service / Sales Page	“SEO services Limerick”

To truly master keyword research for a high-authority blog post, you have to look beyond just the words themselves. You need to understand Search Intent—the specific “why” behind every search query.

In 2026, Google doesn’t just match keywords; it matches solutions. If your content doesn’t provide the exact solution the user is looking for, you won’t rank—even if you write 10,000 words.

Step 4: Search Intent & The Customer Journey

Search intent (also known as “user intent”) is the goal a person has when they type something into a search engine. To capture the right traffic for your Limerick business, you must align your keywords with the four primary types of intent and map them to the Marketing Funnel.

1. Informational Intent (The “Awareness” Stage)

This is the Top of the Funnel (TOFU). At this stage, the user is looking for knowledge, answers, or a solution to a problem they’ve just identified.

The Goal: To learn something.
Example Keywords: “How to do keyword research,” “What is SEO,” or “Why is my website traffic low?”
Content Strategy: This is where your comprehensive blog posts and guides live. You aren’t selling yet; you are building trust by being the most helpful resource in the room.

2. Commercial Intent (The “Consideration” Stage)

This is the Middle of the Funnel (MOFU). The user knows what they need, but they are comparing their options. They are looking for “the best” or “the right” fit.

The Goal: To research and compare.
Example Keywords: “Best SEO tools 2026,” “Top SEO agencies in Limerick,” or “Ahrefs vs Semrush.”
Content Strategy: Comparison articles, “Best of” lists, and detailed reviews. You are helping them move closer to a decision.

3. Transactional Intent (The “Conversion” Stage)

This is the Bottom of the Funnel (BOFU). The user has done their homework and is ready to pull the trigger. They are looking for a place to buy or a person to hire.

The Goal: To take action.
Example Keywords: “Hire SEO consultant Limerick,” “SEO audit price,” or “Buy SEO course.”
Content Strategy: These keywords should lead to your service pages, contact forms, or product checkouts. Keep the copy punchy and focus on your Calls to Action (CTAs).

4. Navigational Intent (The “Branding” Stage)

The user already knows who you are and is using Google as a shortcut to get to a specific page on your site.

The Goal: To find a specific website or brand.
Example Keywords: “Limerick Search Engine Optimisation login” or “Limerick SEO contact page.”
Content Strategy: Ensure your site architecture is clean and your brand name is clearly optimized so users can find you instantly.

How to Identify Intent (The “SERP Test”)

The easiest way to verify intent is to look at the Search Engine Results Page (SERP). Google has already spent billions of dollars figuring out what people want for every keyword.

Before you write, search for your keyword and ask:

Are the results mostly blog posts? (Informational)
Are there product carousels or map packs? (Transactional/Local)
Are there “Best of” lists? (Commercial)

Pro Tip: If you try to rank for a Transactional keyword with an Informational blog post, you are fighting an uphill battle. Always match your content type to what Google is already rewarding.

To build a truly authoritative guide, you need to show your readers how to bypass the standard rankings and jump straight to the top of the page. In SEO, we call these “Quick Wins”—techniques that allow even a smaller Limerick business to beat national competitors by securing “Position Zero.”

Securing a Featured Snippet or a Video Result doesn’t just increase traffic; it builds instant trust by labeling you as the “expert answer” Google trusts most.

Step 5: Capturing “Position Zero” (Snippets & Video Wins)

While traditional rankings are a marathon, winning Featured Snippets and Video Results is about formatting and precision. These “rich results” often appear above the first blue link, giving your blog massive visibility.

5.1 Winning the Featured Snippet (The “Answer Box”)

Google pulls snippets from pages that answer questions clearly and concisely. There are three main types you should target in your blog post:

Paragraph Snippets (The Definition): Best for “What is” or “Why is” queries.
- The Quick Win: Place a direct answer (40–60 words) immediately after an H2 or H3 question heading. Start with the term you’re defining (e.g., “Keyword research is…”).
List Snippets (The How-To): Best for step-by-step processes or “best of” lists.
- The Quick Win: Use proper HTML tags (<ol> for numbered steps or <ul> for bullet points). Google loves clean lists that it can easily extract.
Table Snippets (The Comparison): Best for pricing or feature comparisons.
- The Quick Win: Instead of just writing about costs, create a simple HTML table comparing different services or packages.

5.2 Securing Video Results (The Visual Edge)

In 2026, video is a major ranking factor. A post with an embedded video is 84% more likely to show up on Page 1 than a text-only post.

The “Key Moments” Hack: Google can now show “Key Moments” from your video directly in the search results. To get this, include Timestamps in your video description (e.g., 0:45 – How to use Ahrefs).
Hosting Strategy: While on-site video is great for engagement, YouTube is still the king for search visibility. Embed your YouTube videos near the top of your blog post (“above the fold”).
Transcription Power: Always include a transcript or a detailed summary below your video. Search engines can’t “watch” a video, but they can crawl the text to understand its context.

5.3 Technical “Glue”: Schema Markup

To make sure Google knows exactly what your content is, you need to use Schema Markup. This is a small piece of code that tells Google, “This section is an FAQ” or “This section is a Video.”

FAQ Schema: Using this can result in your questions appearing directly in the search results, taking up more “real estate” and pushing competitors down.

Step 6: Competitor Gap Analysis (Finding the “Weak Spots”)

If you want to rank quickly, you shouldn’t just copy what the top sites in Limerick are doing. You should look for where they are failing. Competitor Gap Analysis is the process of identifying valuable keywords that your competitors rank for, but you don’t—or finding “weak” content on their sites that you can easily outperform.

6.1 The “Keyword Gap” Method

Using tools like Ahrefs, Semrush, or even free manual checks, you can compare your domain against your top 3 rivals. You are looking for:

Missing Keywords: Terms all three of your competitors rank for, but you are nowhere to be found. This is a clear signal that the keyword is relevant to your niche.
Low-Difficulty Wins: Look for keywords where a “weak” competitor (a site with lower authority than yours) is ranking on Page 1. If they can rank there with a mediocre page, you can dominate with an authoritative one.

6.2 Identifying “Thin” Content

Don’t just look at the data—look at the pages. Visit the top-ranking results for your target keywords and look for these “Weakness Indicators”:

Outdated Information: Is the post from 2022? In the SEO world, that’s ancient. An updated 2026 guide will almost always win.
Poor User Experience: Is the page hard to read on mobile? Does it lack images? Is it just a “wall of text”?
Unanswered Questions: Read the comments section or look at “People Also Ask.” If the competitor’s post doesn’t answer those specific questions, you’ve found your gap.

6.3 The “Reddit & Forum” Shortcut

This is a goldmine for gap analysis. If you see a Reddit thread or a Quora answer ranking in the top 3 results for a keyword, it means Google couldn’t find a high-quality “expert” article to put there.

The Strategy: When Google ranks a forum, it’s practically begging for a professional blog post to take its place. These are the easiest keywords to target for fast results.

Common Mistakes to Avoid (The “SEO Pitfalls”)

To ensure your readers succeed, you must warn them about the common traps that ruin even the best keyword research:

Chasing “Vanity” Metrics: Don’t target a keyword just because it has 10,000 searches. If it has 90/100 difficulty and zero “Commercial Intent,” you will waste months with no ROI.
Keyword Stuffing: We are in 2026. Google’s AI is smarter than ever. If you force a keyword into a sentence where it doesn’t belong, you will be penalized for a poor user experience.
Ignoring the “Local” Factor: For a Limerick business, “SEO” is too broad. “SEO for Limerick Accountants” is a niche you can actually own.
The “Set it and Forget it” Mentality: Keyword research isn’t a one-time task. Trends change, and new competitors emerge. Tell your readers to audit their “Topical Map” every six months.
