How to do keyword research free
You know keyword research matters for your organic growth, but every tool you look at wants a credit card before you can see a single search volume. The good news is that free keyword research is not only possible, it can be just as effective if you follow a smart process — and it directly feeds your lead generation and prospecting efforts.
Start With Seed Keywords From Your Own Business
Before you touch any tool, write down 5 to 10 seed keywords based on what you sell and who you sell to. For a B2B founder, these might be broad terms like "sales automation," "lead generation," or "CRM for startups." The goal is to capture the language your ideal customers already use when they describe their problem, not the internal jargon your team uses. Ask your sales reps which phrases come up most often on discovery calls, and mine your own website, pitch decks, and support tickets for recurring words.
Once you have your seeds, expand them using free suggestion tools. Google's autocomplete, "People also ask," and related searches at the bottom of the results page are goldmines. Type your seed into Google and note every variation, question, and long-tail phrase. These represent real queries real people type, and they often reveal buyer intent — someone searching "best lead generation tool for small teams" is much closer to a purchase than someone searching "what is lead generation."
- List 5-10 seed keywords from sales calls, website copy, and customer emails.
- Use Google autocomplete and "People also ask" to find long-tail variations.
- Separate informational keywords from commercial-intent keywords early.
- Group related terms into themes so you can map them to future content.
Use Free Keyword Tools That Actually Deliver
Several free tools give you real data without a paywall. Google Keyword Planner is still the most reliable free source for search volume ranges, especially if you set up a Google Ads account without running a campaign. Ubersuggest, Keywords Everywhere (browser extension), and AnswerThePublic all offer limited free searches per day that are enough for a focused research session. For B2B specifically, Ahrefs Webmaster Tools and Google Search Console show you the exact queries your site already ranks for — this is free and often overlooked.
The trick is not to rely on one tool. Cross-check volume estimates across two or three sources because free tools often show wildly different numbers. Focus more on relative volume and intent than on exact figures. A keyword showing "1K-10K" in Keyword Planner and "2.4K" in Ubersuggest is clearly worth targeting; the precise number matters less than the trend and the competition level.
- Google Keyword Planner for volume ranges without spending on ads.
- Google Search Console to find queries you already rank for.
- Ubersuggest and AnswerThePublic for free daily searches.
- Ahrefs Webmaster Tools for backlink and keyword data on your own site.
Mine Competitor Keywords Without Paying
Your competitors have already done part of the work for you. Use free tools to see what keywords they rank for and where they get traffic. Google Search Console only works for your own site, but you can manually inspect competitor pages and note the terms they target in titles, headings, and meta descriptions. Tools like Ubersuggest let you enter a competitor URL and see a limited list of their top keywords for free. SpyFu offers a handful of free searches per day that reveal competitor ad spend and organic terms.
Pay attention to keywords your competitors rank for but you don't. These are gaps in your pipeline — topics where prospects are searching but finding someone else. Build a simple spreadsheet with columns for keyword, competitor ranking, your current ranking, and intent. That list becomes your content and outreach roadmap. You can also use these insights to refine your prospecting: if a competitor ranks for "sales pipeline software for agencies," that tells you which niche to target with your next reach out campaign.
- Enter competitor URLs into free tools to see their top keywords.
- Note keywords they rank for that you don't — those are your gaps.
- Track intent so you know which terms map to sales-ready prospects.
- Use competitor keyword gaps to guide both content and prospecting outreach.
Validate Keywords With Free SERP Analysis
Search volume alone doesn't tell you if a keyword is worth targeting. Open an incognito browser, search the keyword, and study the first page. If the results are dominated by huge brands like HubSpot, Gartner, or Wikipedia, a new site will struggle to rank. If you see forums, Quora threads, or small blogs, that's a sign the keyword is winnable. Also check whether the results match the intent you assumed. A keyword like "lead generation" might return mostly definitional content, while "lead generation software for B2B" returns product pages — those require completely different content strategies.
Look at the "People also ask" box and related searches for each keyword. These give you sub-topics and question-based keywords that are easier to rank for and often convert better because they match specific pain points. Save every question you find; they become FAQ sections, blog posts, and even cold email angles. When you reach out to a prospect, referencing a specific problem they're likely searching for makes your message far more relevant than a generic pitch.
- Search in incognito to see unbiased results for your target keyword.
- Avoid keywords dominated by massive brands unless you have a unique angle.
- Check that SERP intent matches your content format (blog vs. product page).
- Harvest "People also ask" questions for FAQs and outreach personalization.
Turn Keywords Into a Content and Outreach Plan
Keyword research is only useful if it feeds your pipeline. Group your keywords into three buckets: informational (top of funnel), commercial (middle), and transactional (bottom). Informational keywords become blog posts and guides that attract early-stage prospects. Commercial keywords become comparison pages, case studies, and landing pages. Transactional keywords become product pages or demo request pages. Map each bucket to a stage in your sales funnel so you know what action you want the reader to take.
For lead generation, pair your keyword list with your prospecting efforts. If you discover that many prospects search for "how to reduce churn in SaaS," you can write a post on that topic and then reach out to companies showing churn-related signals on LinkedIn. The keyword becomes a conversation starter, not just a ranking target. Over time, track which keywords drive contacts, demo requests, and closed deals — that's the only metric that truly matters for sales.
- Bucket keywords by funnel stage: informational, commercial, transactional.
- Assign each keyword a content format and a call to action.
- Use keyword insights to personalize prospecting messages and reach out.
- Measure which keywords generate contacts and pipeline, not just traffic.
Track Rankings and Iterate for Free
Once you publish content around your target keywords, you need to track performance without paying for rank trackers. Google Search Console is your best free option — it shows impressions, clicks, average position, and the exact queries people use to find you. Check it weekly to see which keywords are climbing and which are stuck. If a page ranks on page two for a valuable keyword, a small update (better title, more depth, internal links) can push it to page one.
Set up a simple Google Sheet to log your target keywords, current rankings, and the content piece targeting each one. Update it monthly. This habit forces you to prune keywords that aren't working and double down on those that are. Remember that keyword research is not a one-time task — search trends shift, competitors publish new content, and your own product evolves. The free tools are more than enough to keep you competitive if you stay consistent.
- Use Google Search Console weekly to monitor queries and positions.
- Log target keywords and rankings in a simple spreadsheet.
- Refresh pages stuck on page two with better titles and depth.
- Revisit your keyword list monthly and adjust based on performance.
Free keyword research is a skill, not a budget line. Start with your seeds, validate them with free tools and SERP analysis, then turn every insight into content and outreach that moves your pipeline. Pick one section above and block 30 minutes this week to build your first keyword list — your future leads will thank you.
