What is Keyword Research (and Why It’s Your Most Important SEO Task)?
Keyword research is the process of finding and analyzing the search terms that people enter into search engines.
The goal is to find topics and phrases that your target audience is looking for.
This process helps you understand what content to create. It also helps you understand how to optimize that content.
Effective keyword research provides a roadmap for your content strategy. It ensures you are not just creating content you think your audience wants.
Instead, you are creating content that you know they are actively searching for. This is the core principle of a successful WordPress SEO strategy.
Understanding Search Intent: The Why Behind the Search
Before you look for keywords, you must understand search intent.
This is the underlying goal a user has when they type a query into a search engine.
In 2026, Google’s algorithm is incredibly sophisticated at understanding intent. Matching your content to that intent is non-negotiable.
There are three main types:
- Informational: The user wants to learn something. They are looking for an answer to a question.
Examples: how to bake sourdough bread?, what is SEO? - Transactional: The user wants to buy something. They are ready to make a purchase.
Examples: buy Nike running shoes at the best price for iPhone 16. - Navigational: The user wants to find a specific website or page.
Examples: Facebook login, YouTube.
Your blog posts will primarily target informational intent. Your product or service pages will target transactional intent.
How to Do Keyword Research for WordPress Sites: A 5-Step Process
Step 1: Brainstorm Your ‘Seed’ Keywords
Your seed keywords are the foundational topics that define your business or niche. They are usually broad one or two-word terms.
They are the starting point for finding more specific keyword ideas.
Do not overthink this step. Just write down 5-10 topics that are central to what you do.
How to Brainstorm
- Think like your customer. If you were looking for your product or service, what would you type into Google?
- Write down the main problems your business solves.
- List the main categories of products or services you offer.
Example: If you run a website about home gardening, your seed keywords might be:
- vegetable gardening
- indoor plants
- gardening for beginners
- organic fertilizer
- container gardening
Step 2: Use Keyword Research Tools to Expand Your List
Now you will take your seed keywords and plug them into keyword research tools.
These tools will give you thousands of related keyword ideas along with important data for each one.
The Best Keyword Research Tools
- Semrush and Ahrefs: These are the industry-leading all-in-one SEO platforms. They provide the most accurate data on search volume, keyword difficulty, and competitor keywords. They are premium tools, but are essential for any serious SEO strategy.
- Google Keyword Planner: This is Google’s free tool for advertisers. It is a great resource for discovering new keyword ideas directly from the source. You will need a Google Ads account to use it, but you do not have to run ads.
- Ubersuggest: This tool offers a good balance of features with a generous free tier. It is an excellent starting point for beginners.
When you enter a seed keyword, these tools will give you a long list of related terms.
For example, entering vegetable gardening might give you when to plant a vegetable garden in zone 7 or the best vegetable garden layout ideas.
Step 3: Analyze and Qualify Your Keywords
A long list of keywords is useless without analysis.
Now you need to filter your list to find the best opportunities. Keep in mind these three key metrics for each keyword.
Search Volume
This metric tells you how many times a keyword is searched for per month on average.
Higher search volume means more potential traffic.
But it also usually means more competition.
Keyword Difficulty
This is a score (usually out of 100) that estimates the difficulty of ranking on the first page of Google for a given keyword.
Tools like Ahrefs and Semrush provide this score.
As a new WordPress site, you should target keywords with a lower difficulty score. This gives you a realistic chance to rank.
Relevance and Intent
This is the most important step.
Look at each keyword and ask yourself:
- Is this truly relevant to my business?
- Does my type of content match the search intent of this keyword?
A high-volume, low-difficulty keyword is worthless if it is not relevant to what you offer.
Step 4: Analyze Your Competitors
You do not have to reinvent the wheel. Your competitors can provide a treasure map of valuable keywords.
Most premium SEO tools allow you to enter a competitor’s domain and see all the keywords they are ranking for.
How to Conduct a Competitor Keyword Analysis
Identify 3-5 of your top direct competitors in the search results.
Use a tool like Semrush or Ahrefs to run their domain through a keyword gap or organic keywords report.
Look for keywords that they are ranking for but you are not.
Pay special attention to keywords where they are ranking with a blog post or guide that you know you can create a better version of.
This is a powerful way to find proven keyword opportunities.
Step 5: Map Keywords to Your Content Strategy
The final step is to organize your chosen keywords and map them to your website’s structure and content plan. This is how you turn research into action.
How to Map Keywords:
- Broad Transactional Keywords: Map these to your main category pages or service pages. (e.g., WordPress SEO services).
- Specific Product Keywords: Map these to your individual product pages. (e.g., Yoast SEO premium plugin).
- Informational Long-Tail Keywords: These are perfect for your blog posts. Each blog post should target one primary long-tail keyword and a few related secondary keywords.
Create a content calendar or a simple spreadsheet.
List the keywords you will target. Then plan out the blog posts and pages you will create for each one.
This ensures your WordPress SEO efforts are organized and strategic.

Frequently Asked Questions (FAQ)
1. How many keywords should I use in a single blog post?
You should focus on one primary keyword per post. This is your main target. You can then include 3 to 5 secondary or related keywords naturally throughout the content. This helps Google understand the full context of your article. Do not force keywords where they do not fit.
2. Where can I find keyword ideas for free?
Google itself is a powerful free tool. Use the Google search bar autocomplete, the People Also Ask boxes, and the Related searches at the bottom of the results page. Google Keyword Planner and the free version of Ubersuggest are also excellent starting points.
3. What is a good keyword difficulty score to target for a new website?
For a new WordPress site with low domain authority, it is best to target keywords with a Keyword Difficulty score of 30 or below (on a scale of 100). As your site builds authority over time, you can start to target more competitive keywords.
4. Should I still target keywords with very low search volume?
Yes absolutely. Keywords with only 10-50 searches per month can be extremely valuable. These long-tail keywords are often highly specific. The users searching for them have a very clear intent. This means the traffic they generate is often much more likely to convert into a lead or a customer.
