Why Keyword Research Matters
Keyword research is the foundation of every successful SEO strategy. If you optimize for the wrong keywords, you will never get traffic — no matter how good your content is. The goal is to find terms that have decent search volume but low competition, so you can rank quickly.
4 Free Keyword Research Tools
1. Google Keyword Planner
Free (requires Google Ads account). This is Google's own tool, so the data is the most accurate. It shows monthly search volume, competition level, and suggested bid prices.
How to use it: Enter a seed keyword (e.g., "SEO tools") and it will generate hundreds of related keyword ideas. Filter by "Low" competition to find easy-to-rank terms.
Pros: Most reliable data, directly from Google. Cons: Shows broad ranges instead of exact numbers for low-volume keywords.
2. Ubersuggest (by Neil Patel)
Free tier: 3 searches per day. Ubersuggest is beginner-friendly with a clean interface. It shows search volume, CPC, SEO difficulty, and content ideas.
How to use it: Type in a keyword and go to "Keyword Ideas." Look for keywords with a "Suggested" difficulty score under 40 — these are typically achievable for new sites.
Pros: Easy to use, includes content suggestions. Cons: Limited daily free searches.
3. AnswerThePublic
Free tier: 1 search per day. This tool visualizes search queries as questions (who, what, when, where, why, how) and prepositions, based on Google autocomplete data.
How to use it: Enter a topic and get a wheel of questions people are asking. These make excellent blog post titles and FAQ sections.
Pros: Great for content ideas, shows long-tail questions. Cons: Limited daily searches, no volume data.
4. AlsoAsked
Free tier: Limited searches. AlsoAsked compiles the "People also ask" boxes from Google into a visual tree structure. It reveals the related questions users have after searching for your keyword.
How to use it: Search a keyword and explore the question tree. Each branch represents a related search intent — perfect for structuring a comprehensive article.
Pros: Shows real user intent, visual and intuitive. Cons: Free tier is limited.
How to Find Low-Competition Keywords
- Start broad: Pick a topic you know well (e.g., "vegan recipes").
- Use Google Keyword Planner or Ubersuggest to generate keyword ideas.
- Filter by question format: "how to," "what is," "best" — these often have lower competition.
- Analyze the SERP: Search for the keyword on Google. If the top results are thin, outdated, or from small blogs, you have a good chance to outrank them.
- Check with AlsoAsked: See what questions people ask about this topic. Each question can be a separate article or a section within a comprehensive guide.
