Can I do keyword research for free?

Yes. Google Autocomplete, People Also Ask, AnswerThePublic free tier, Reddit search, and AI tools like ChatGPT provide enough keyword ideas to build a content strategy without any paid tools.

How do I find low competition keywords for free?

Search your target keyword in Google and look at the first page results. If you see small blogs and low-authority sites ranking, it is likely lower competition. Use AnswerThePublic for long-tail question variants.

What is a long-tail keyword?

A long-tail keyword is a longer, more specific search phrase. "pdf compressor" is a head term; "how to compress pdf without losing quality" is a long-tail keyword. Long-tail keywords have lower search volume but higher conversion rates and are easier to rank for.

Keyword Research Without Paying for Tools: Free Methods That Work in 2026

Why Expensive Keyword Tools Are Overrated for Beginners

Ahrefs costs $99/month. SEMrush costs $129/month. For a new website with no traffic, these tools tell you that competing keywords have high difficulty — information that does not help you rank against sites with thousands of backlinks.

Free keyword research is not just adequate for beginners — it may be more appropriate, because the free methods bias toward question-based queries (what do people actually type?) rather than volume metrics (how many people theoretically search this?).

Free Method 1: Google Autocomplete (Underused)

Start typing any query in Google and watch the autocomplete suggestions. These are real searches people are making. They represent high-intent, specific queries.

For example, type "how to compress" and you see: "how to compress pdf", "how to compress video", "how to compress image for email", "how to compress pdf without losing quality".

Advanced technique — alphabet soup: After your main keyword, add each letter of the alphabet and record suggestions. "how to compress pdf a", "how to compress pdf b"... Most letters surface unique queries.

Free Method 2: Google's "People Also Ask" and "Related Searches"

Search any topic. Scroll through the results. Google shows "People also ask" boxes (questions real searchers have) and "Related searches" at the bottom.

These are pure gold for content ideas because Google is explicitly telling you what people are searching for around your main topic.

Export technique: For any important topic, manually note all PAA questions. These become your H2 and H3 headings and FAQ sections — directly addressing what Google knows people want to know.

Free Method 3: AnswerThePublic (Free Tier)

answerthepublic.com shows hundreds of questions people ask around any keyword, grouped by: questions (who, what, when, where, why, how), prepositions (for, near, with, without), comparisons (vs, like, and, or).

Free tier: 3 searches per day. Enough for focused research.

Example: Search "pdf compressor" and see questions like "pdf compressor that doesn't reduce quality", "pdf compressor for mac free", "pdf compressor below 100kb" — specific, intent-rich queries that are easier to rank for than the head term.

Free Method 4: Reddit for Actual User Language

Search "[your topic] site:reddit.com" in Google. Read how real people describe their problems. The exact phrases they use are the keywords you should target — because other people with the same problem search for the same phrases.

Also: subreddit search bars show auto-suggestions based on what people in that community actually type.

Free Method 5: AI Tools for Keyword Brainstorming

ChatGPT, Claude, or Gemini — prompt: "Give me 20 specific, long-tail questions someone would search for when they want to [do your topic]. Include questions at beginner, intermediate, and advanced levels. Focus on questions with a clear answer intent."

AI does not know actual search volumes, but it is excellent at generating the natural-language questions real humans ask.

Evaluating Keyword Difficulty Without Paid Tools

Look at the first page of Google for your target keyword:

Are results from major publications (Wikipedia, Forbes, government sites)? Hard to compete.
Are multiple results from small blogs or unknown sites? Opportunity.
Does the first result have a weak title that barely matches the query? Opportunity.
Does Google show "About X results" under 100,000? Often low competition.

Domain Authority proxy: Check how many external links the top-ranking pages have using Moz's free Link Explorer (10 free searches/month).

Long-tail vs Head Term Strategy

For new sites: Target long-tail keywords (3-5 words, highly specific, under 1,000 searches/month). These are easier to rank for, convert better because the intent is specific, and build your site's authority in the topic area.

Example progression:

Month 1-6: Target "how to compress pdf without losing quality" (long-tail)

Month 6-12: Target "compress pdf" (medium)

Year 2+: Target "pdf compressor" (head term)
