The best keyword research tools in 2026 for most beginners are free: Google Search Console, Google Keyword Planner, Google Trends and Google’s own search results. Add one free-tier tool such as AnswerThePublic or AlsoAsked for questions, and an AI chatbot for idea lists. Buy a paid suite like Semrush or Ahrefs only when you manage several sites or clients and need competitor data every day.
“Paid tools bahut mehnge hain.” We hear this in almost every SEO batch. A student sees a $100+ monthly price, gets scared, and thinks SEO is not for them. The truth is that you can do solid keyword research on a zero budget. This post compares the free and paid keyword research tools that still exist in October 2026, what each one is genuinely good at, and when paying is worth it.
How to choose keyword research tools (before you look at any list)
Ask yourself three questions first:
- Do I have a live website? If yes, Search Console is your most accurate tool, because it shows real queries for your own site.
- Do I need competitor data? Only paid suites show, in depth, which keywords another site ranks for.
- How many sites do I handle? One blog or business site rarely needs a paid plan. An agency or freelancer with clients usually does.
Tools only give data. The thinking (intent, grouping, page mapping) is still yours. Our step-by-step keyword research guide covers that process; this post is only about the tools.
Free keyword research tools that are enough to start
Google Search Console (free)
Shows the actual queries that bring impressions and clicks to your site, with position and CTR. Google states that traffic from AI Overviews and AI Mode is included in the Performance report under “Web” (Google Search Central). Limit: only works for sites you own, and only shows queries you already appear for.
Google Keyword Planner (free with a Google Ads account)
Gives keyword ideas and search volume, filtered by country or city. Without active ad spend it usually shows broad ranges such as 1K–10K rather than exact numbers. Good for comparing ideas and for checking local terms like “Jaipur”.
Google Trends (free)
Shows whether interest in a topic is rising, falling or seasonal, and compares terms. Useful for timing content, for example internship searches before summer.
Google search itself (free)
Autocomplete, People Also Ask and related searches are real user questions. Many trainers, including us, consider this the most underrated research tool.
Bing Webmaster Tools (free)
Has a keyword research feature, and since 10 February 2026 an AI Performance report in public preview. It shows how often your pages are cited as sources in Microsoft Copilot and Bing’s AI summaries, which pages are cited, and a sample of the “grounding queries” the AI used to find your content (Bing Webmaster Blog). For keyword research, those grounding queries show how AI tools phrase questions in your niche.
Free-tier and low-cost question tools
AnswerThePublic
Turns one seed word into a map of questions and prepositions (“SEO for…”, “SEO vs…”). The free tier allows only a few searches a day; paid plans raise the limit. Check the current limits on its own pricing page, as they have changed more than once.
AlsoAsked
Pulls People Also Ask questions and shows how they branch into follow-up questions, which is close to how AI search explores a topic. AlsoAsked’s help centre says free users get 3 search credits, refreshed every day. Paid plans add more searches and deeper question trees; check the current price on its pricing page before you buy.
Keywords Everywhere
A browser extension that shows volume and related keywords right inside Google results. It now runs mainly on paid credit packs, so treat it as a low-cost paid tool rather than a free one.
Moz Keyword Explorer, Keyword Tool, Serpstat, Wordtracker
All four offer some kind of limited free version or trial, with small daily caps that change often. Good for occasional checks when you do not want to pay yet. Do not build your whole process on one tool’s free tier.
Paid keyword research tools: when they are worth it
Semrush
A full SEO and marketing suite: keyword database, competitor research, site audit, rank tracking. A free account gives about 10 keyword research and 10 domain queries a day, per Semrush’s own blog. Paid plans start at the Pro tier, from about $139.95 a month on monthly billing as of October 2026 (SEO.com pricing breakdown); check the current price on Semrush’s own pricing page before you pay.
Ahrefs
Strong for backlinks and competitor keyword gaps. Its free option (Ahrefs Webmaster Tools) gives limited Site Explorer and Site Audit data for your own verified sites. Ahrefs’ official pricing page listed, in October 2026, a Starter plan from $29 a month and full plans from $129 a month (Lite) on monthly billing; check the page on the day you buy.
Prices change often and are in US dollars before taxes. Always check the tool’s official pricing page on the day you buy. We have not been paid to list any tool here.

Using AI chatbots as keyword research tools
ChatGPT, Gemini and similar assistants cannot tell you how many people search a phrase. What they do well is think like a buyer. Try prompts such as:
- “List 25 questions a small shop owner in Jaipur asks before hiring an SEO freelancer.”
- “Group these 60 keywords by search intent and suggest one page for each group.”
- “What follow-up questions would someone ask after reading a guide on 301 redirects?”
Then check each idea in Google. If autocomplete or People Also Ask shows something similar, keep it. If not, drop it. For deeper prompt methods, see our guide to finding long-tail keywords with AI prompts.
What changed in 2026
- AI visibility data has started arriving. On its Search Central Blog in June 2026, Google announced Search Generative AI performance reports in Search Console, rolling out to a subset of sites first. They show impressions and pages in AI Overviews, AI Mode and Discover AI features, not clicks or queries.
- Bing went first with citations. Its AI Performance report (public preview, February 2026) shows Copilot citations and grounding queries.
- Paid suites added AI visibility trackers. Several big tools now sell “AI visibility” add-ons or bundles. They are useful for agencies, but a beginner does not need them to start.
Learn Search Console and Google’s own results really well before you pay for anything. A student who can read a Search Console report beats a student who only knows how to click buttons in a paid tool.

Not sure which tools you actually need? In a free demo SEO class we show the zero-budget stack on a live site and help you plan what to learn next.
Who should NOT buy a paid tool yet
If you have one small site, fewer than 50 pages, or you are still learning the basics, a paid tool will mostly sit unused. Spend those months learning intent, SERP analysis and Search Console. Buy a paid plan when you have clients who pay for the work, or use a free trial only for a specific project.
How Infonic helps
Our SEO training course in Jaipur teaches keyword research with free Google tools first, then shows how professional suites are used in agencies. You practise on real websites and build a keyword map you can show in interviews. Tracks: 15 days, 45 days or 3 months, offline or online (same live class, with recordings). If you are a student who wants agency-style practice, the SEO internship guide explains what tasks to expect.
Frequently asked questions
Which is the best free keyword research tool?
For a site you own, Google Search Console, because it shows the real queries people use to find you. For new keyword ideas, Google Keyword Planner and Google’s own autocomplete and People Also Ask boxes are the best free starting points. Combine them rather than relying on one.
Is Ubersuggest still available?
Yes, Ubersuggest is still offered, with a limited free option and paid plans. Its daily free limits and plan prices have changed several times, so check the official site before relying on it. Many beginners find it simpler than Semrush or Ahrefs, though its database is smaller.
Semrush or Ahrefs: which should I learn?
Both are used in agencies, and the skills transfer between them. Semrush is a wider marketing suite; Ahrefs is often preferred for backlink analysis. If a job or client already uses one, learn that. Otherwise start with the free versions of both and decide based on what you use most.
Kya free tools se client ka kaam ho jayega?
For small local clients, often yes. Search Console, Keyword Planner, Google results and Trends can cover keyword research for a clinic, coaching centre or shop. For competitive niches or competitor gap reports, a paid tool saves many hours, and clients usually understand that cost is part of the service.
Are AI keyword tools accurate?
AI tools are good at ideas and grouping, but not at numbers. Many show volumes pulled from other databases, while chatbots may guess. Treat any AI keyword list as a draft and confirm each keyword in Google or Search Console before writing a page for it.
Do I need a paid tool to get an SEO job?
No. Employers care that you can find the right keywords, map them to pages and explain your reasoning. Knowing one paid tool helps in interviews, and free accounts or trials are enough to learn its interface. A portfolio showing your keyword maps matters more.
