Step-By-Step Guide to Doing Keyword Research (Without Spending Money)

Step 1: Start with Seed Keywords

Begin by brainstorming core topics related to your niche, products, or services. These are your seed keywords—broad terms that capture the essence of what you offer. For example, if you run a fitness blog, seed keywords might include “workouts,” “nutrition,” or “weight loss”.

Step 2: Understand Search Intent

Identify the intent behind each seed keyword:

• Informational (seeking knowledge)
• Navigational (looking for specific websites)
• Transactional (ready to buy or take action)
• Commercial investigation (comparing options)

Knowing the intent helps you filter keywords to target those that align with your content goals.

Step 3: Utilize Google Search Console and Google Autocomplete

Use Google Search Console to analyze your existing traffic and discover keywords already driving visitors to your site, offering insights into what works.
Next, leverage Google Autocomplete by starting to type your seed keywords into Google; the suggested completions are excellent indicators of popular long-tail keywords.

Step 4: Explore Google Related Searches

Scroll to the bottom of Google’s results page to find related searches. These terms reveal additional keyword ideas and variations that users frequently search for.

Step 5: Conduct Competitor Keyword Analysis

Identify your top competitors’ websites and analyze their most valuable keywords. You can do this without paid tools by manually examining:

• Their page titles and headings for keyword clues
• Using Chrome extensions like Keywords Anywhere to see keywords in their page source
• Analyzing their top-ranking pages through Google’s “People also ask” and snippet features.

Step 6: Implement Keyword Clustering Without Tools

Group similar keywords based on topic and search intent—this is called keyword clustering. Manually, you can create clusters by categorizing keywords into themes or subtopics, which simplifies content planning and SEO strategies.

Step 7: Validate Keywords

Assess each keyword’s potential by estimating search volume and difficulty manually:

• Use Google Trends for trends patterning over time.
• Search the keyword and note the number of results to gauge competition.
• Look at the quality of ranking pages: if they are high-authority sites, the keyword might be more competitive.

Step 8: Prioritize Your Keywords

Focus on keywords with moderate to high search volume but low to medium difficulty. Long-tail keywords (more specific phrases) often have less competition and higher conversion potential.

Step 9: Plan Your Content Based on Keyword Data

Design your content around the targeted keywords, ensuring the primary keyword “how to do keyword research” is naturally integrated. Use secondary keywords seamlessly, maintaining keyword density around 2% for optimal SEO.

• Search volume indicates demand. Focus on keywords with enough monthly searches to warrant targeting.
• Keyword difficulty assesses how hard it is to rank. Aim for low to medium difficulty keywords, especially if your site is new.
• Relevance ensures your keywords match your content and user intent.

Prioritize long-tail keywords as they are less competitive and tend to convert better. Validate your selections by reviewing top-ranking pages and ensuring your content can compete on quality.

How to Organize Your Keywords Like a Pro

Organize keywords into logical groups or clusters based on topic, intent, and user journey stages. Create a spreadsheet with columns like:
