Keyword research has a reputation for being pay-to-play. Scroll through any SEO forum and you’ll see people insisting you need Ahrefs, SEMrush, or Moz just to get started. The truth is more forgiving: most of the real signal in keyword research what people actually type, what they mean by it, and how hard it’ll be to rank is available for free if you know where to look. Paid tools mostly save you time, not insight.
Here’s how to do solid keyword research using nothing but free resources.
1. Start With Google Autocomplete
Type a seed keyword into Google’s search bar and don’t hit enter. The dropdown suggestions are real queries pulled from actual search volume Google is showing you what people search for around your topic.
Go further by typing your keyword followed by each letter of the alphabet best running shoes a,best running shoes b, etc.. This “alphabet soup” technique surfaces long-tail variations you’d never brainstorm on your own.
2. Mine the “People Also Ask” and Related Searches Boxes
Every Google results page includes a “People Also Ask” box and a “Related searches” section at the bottom. These are goldmines because they show you:
- The actual questions people have around your topic
- Related concepts and subtopics worth covering
- Language and phrasing real searchers use
Click into a few PAA questions they expand and often reveal even more related questions, letting you go several layers deep on a single search.
3. Use Google Search Console (If You Have an Existing Site)
If your site already has some traffic, Search Console is arguably the single best free keyword tool available, because it shows queries your site already ranks for including impressions, clicks, and average position. Look for:
- Queries with high impressions but low click-through rate (a sign your title/meta needs work)
- Queries where you rank on page 2 positions 11–20, since these are often the easiest wins to push onto page 1
- Unexpected queries you didn’t intentionally target, which can reveal new content angles
4. Steal Ideas From Reddit, Quora, and Forums
Real people ask real questions in their own words on these platforms, unfiltered by SEO-speak. Search “your topic reddit” or browse relevant subreddits and Quora spaces. Pay attention to:
- How questions are phrased this is often closer to voice search and conversational queries
- Recurring pain points or confusion
- Comments that reveal what answers people found unsatisfying elsewhere a content gap you can fill
5. Try Google Trends for Direction and Seasonality
Google Trends won’t give you exact volume, but it’s excellent for:
- Comparing relative interest between two or more keywords
- Spotting seasonal patterns so you can publish ahead of demand
- Catching rising topics before they get competitive
6. Use Free Tiers of “Freemium” Tools
Several proper keyword tools offer generous free tiers that cover most small-to-medium research needs:
- Ubersuggest limited free searches per day, includes volume and difficulty estimates
- AnswerThePublic visualizes questions and prepositions people search around a keyword
- Google Keyword Planner technically built for ads, but usable for free with a Google Ads account (volume shows as ranges without active ad spend, but it’s still directionally useful)
- Bing Webmaster Tools’ Keyword Research tool often overlooked, and gives actual search volume numbers for free
7. Check Competitor Content Manually
You don’t need a paid tool to see what’s working for competitors you need a browser. Search your target keyword, open the top 5–10 ranking pages, and note:
- Common subheadings and structure across multiple articles
- Topics they all cover a sign it’s expected content versus topics only one covers a possible differentiation angle
- Word count and content depth as a rough difficulty signal
8. Estimate Difficulty Without a Difficulty Score
Paid tools boil ranking difficulty down to a single number, but you can approximate it manually by checking:
- Domain strength of top results if the first page is packed with major brands or high-authority sites, it’ll be harder to compete
- Content quality thin, outdated, or poorly structured top results signal an opportunity
- Search intent match if your intended content type blog post, product page, video doesn’t match what’s currently ranking, you’re fighting an uphill battle regardless of authority
Putting It Together
A free keyword research workflow looks something like this:
- Brainstorm seed keywords based on your niche
- Expand each seed using Autocomplete, PAA, and Related Searches
- Cross-check phrasing and pain points on Reddit/Quora
- Validate volume direction with Trends and a freemium tool
- Pull real performance data from Search Console if available
- Manually assess the competition on page one before committing
None of this requires a subscription. It requires more manual effort than clicking “generate report” in a paid tool — but the tradeoff is time for money, and for many bloggers, freelancers, and small business owners, that’s a trade worth making.
Paid tools become genuinely valuable once you’re managing dozens of clients or need to track large volumes of keywords over time. Until then, free tools and a bit of manual digging can get you further than most people expect.
