Free Keyword Research Tool

Most free keyword tools pull from databases that update once a month or less. That means the search volumes, difficulty scores, and CPC values you see may already be outdated by the time you use them. This tool works differently: it queries Google data in real time, pulling directly from active Google Ads auctions and organic search results at the moment of your search.

That matters because search behavior shifts constantly. Seasonal trends, industry events, and algorithm updates all change which keywords are worth targeting. Real-time data means you can spot these shifts as they happen, rather than making decisions based on stale numbers from weeks ago.

Each keyword result includes four data points. Here is what they mean and how to use them:

• Search Volume (SV) is the estimated number of monthly Google searches for that keyword. Keep in mind that this is an average, and actual clicks may be lower if the SERP is heavy with ads, featured snippets, or other non-organic features.
• Keyword Difficulty (KD) is a score from 0 to 100 that estimates how competitive the top 10 results are for that keyword. Lower scores mean the current ranking pages have weaker link profiles, making it easier for a newer site to compete. If your site is relatively new, focusing on keywords with a KD under 20 gives you a realistic shot at page one.
• CPC (Cost Per Click) is the average amount advertisers are paying per click in Google Ads. Even if you are not running ads, CPC is a useful proxy for commercial value. A keyword with a $5 CPC is almost certainly driving purchases, while a $0.05 CPC usually signals purely informational searches.
• Search Intent classifies what the user is looking for. Informational queries seek answers or knowledge. Commercial queries compare products or services. Transactional queries indicate readiness to buy. Navigational queries look for a specific website. Matching your content format to the intent (e.g., a comparison post for commercial intent, a product page for transactional) is one of the most reliable ways to rank.

Click the Advanced button next to the location and language dropdowns to open the filter panel. These filters run before your search hits Google, which means you only get back the keywords that actually fit your criteria. Instead of pulling 50 broad suggestions and sifting through them by hand, you can ask for the exact slice you want and skip the noise. You can combine up to 8 filters per search.

Returns only keywords that start with a question word (who, what, when, where, why, how, can, does, will, and similar). Question keywords almost always signal informational intent and tend to be lower-difficulty than broader terms. They are also a fast way to build a topic cluster: a single seed can surface dozens of question variations, each one a viable blog post or FAQ entry.

Both fields accept comma-separated terms. Use the dropdown next to each one to switch between Any (match if the keyword contains at least one term) and All (match only if every term is present).

By default, terms match as substrings, so “run” will match “running,” “runner,” and “run.” Wrap a term in double quotes to force an exact word match: “run” will match only the standalone word and ignore “running.”

Common uses: include your brand name or product category to keep results tight, or exclude terms like “free,” “cheap,” “reddit,” or “youtube” if you want to filter out bargain hunters and forum-heavy searches.

Set a minimum and/or maximum monthly search volume. A common pattern is setting a minimum of 100 to filter out near-zero-volume keywords that may not be worth the effort, while capping the maximum at 5,000 or 10,000 to avoid the most competitive head terms. For new sites, the sweet spot is often 100 to 2,000 searches per month.

CPC (cost per click) is what advertisers are paying per click in Google Ads for that keyword. It is one of the most reliable proxies for commercial intent. Setting a minimum CPC of $1 or higher is a shortcut for “people are buying around this topic.” Setting a maximum is rarely useful unless you are deliberately hunting purely informational keywords for top-of-funnel content.

Filter by the 0–100 keyword difficulty score. The most common use is capping the maximum to find rankable keywords for your site:

• Under 20: very accessible, suitable for brand-new sites with little authority.
• Under 40: realistic for established sites with some content and a few backlinks.
• Under 60: reachable with strong content and a healthy backlink profile.
• 60+: typically dominated by major brands and high-DR sites; usually only worth pursuing if you already rank well in the niche.

Pick one or more intent types: informational, navigational, commercial, or transactional. The dropdown lets you stack multiple intents (selected intents appear as removable pills below the dropdown). If you are building top-of-funnel content, filter to informational. If you are building affiliate or product pages, filter to commercial and transactional and skip the rest.

You can drop an asterisk (*) into the seed keyword itself to use it as a wildcard, in addition to the filters. A few examples:

• best * for runners matches phrases like “best shoes for runners,” “best protein for runners,” “best socks for runners.”
• how to * a website matches “how to build a website,” “how to launch a website,” etc.
• marketing * matches any phrase that starts with “marketing.”

Wildcards are powerful for content brainstorming because they surface variations you would not think to type out manually. Combine them with Difficulty and CPC filters and you have a fast way to map every angle of a topic that is both rankable and commercial.

• Buyer-intent questions you can rank for: Questions only ON, Difficulty max 40, CPC min 1, Doesn't contain “free, cheap.” Returns rankable question keywords with proven commercial value.
• Top-of-funnel content for a new blog: Volume min 100, Difficulty max 20, Intent: informational. Returns easy-to-rank-for educational keywords with enough volume to matter.
• Affiliate review opportunities: Contains “best, top, vs, review,” CPC min 2, Difficulty max 50, Intent: commercial. Returns “best of” and comparison keywords with advertiser interest.
• Product or service pages: Intent: transactional, CPC min 1, Difficulty max 50. Returns keywords with buying intent that you have a real shot at ranking for.

By default, this tool returns the highest-volume keyword suggestions for your seed. That is a fine starting point, but those top-of-the-list results tend to be the most competitive head terms — exactly the keywords you have the least chance of ranking for. The Advanced filters fix that by narrowing the list before it comes back, so you only see keywords that fit your criteria. Here is a four-step workflow that works for most sites:

1. Enter a broad seed term. Pick a general topic for your niche. If you run a project management blog, try “project management software.” Without filters, the tool returns the highest-volume suggestions, which are usually the head terms major sites already dominate.
2. Open Advanced and cap the difficulty. Set Keyword Difficulty max to 30 if your site is new, or 40 if you have an established site with some authority. This removes every keyword where the current top 10 is dominated by high-DR sites and leaves only the ones with a realistic ranking opportunity. This is filtering, not sorting — the high difficulty keywords are removed from the results entirely, not pushed to the bottom.
3. Add a CPC minimum to filter for commercial value. Set CPC min to $1. CPC is what advertisers pay per click in Google Ads, so a healthy CPC is direct evidence that real money changes hands around the keyword. This filter removes the keywords nobody is paying to advertise on, which usually correlates with keywords nobody is buying around.
4. Optionally narrow further with intent or exclusions. If you want only commercial keywords (best-of, comparison searches), pick that in the Search Intent filter. Use Doesn't contain to drop noise terms like “free,” “cheap,” or “reddit” if those pull in the wrong audience.

The result: instead of 50 high-volume head terms you cannot rank for, you get a tighter list of low-difficulty, commercially relevant keywords with real opportunity. This is the difference between sorting through a stack of results and asking the tool the right question in the first place.

It is tempting to chase keywords with tens of thousands of monthly searches, but high volume almost always means high competition. For a smaller website, ranking #1 for ten keywords with 200 searches each will drive more total traffic than being stuck on page five for a single keyword with 20,000 searches.

Long-tail keywords (longer, more specific phrases like “best project management app for remote teams”) typically have lower search volume but convert at a much higher rate. Visitors searching for specific phrases already know what they want, which makes them more valuable for both content engagement and sales.

Understanding intent is arguably the most important part of keyword research. If you write a blog post for a keyword where Google shows product pages in the top 10, you will struggle to rank because the content format does not match what users (and Google) expect. Use the intent column to guide your content decisions:

Informational keywords sit at the top of your funnel. Someone searching “how does keyword research work” is not ready to buy a tool yet, but by providing a helpful answer, you build trust and become the obvious choice when they are ready. Transactional keywords like “keyword research tool pricing” signal someone with buying intent. These tend to be more competitive, but they also deliver the highest return when you can rank for them.

Google offers the Keyword Planner inside the Google Ads platform, and while you can access it without spending money on ads, it is built for advertisers, not SEO professionals. That means it groups similar keywords together, shows volume as broad ranges (like “1K–10K”) rather than specific numbers, and lacks difficulty data entirely.

This free keyword tool fills those gaps by giving you specific search volume numbers, keyword difficulty scores, and search intent classification alongside CPC, all without requiring an active ad spend or Google Ads account.

This free tool shows you keyword ideas with basic metrics. ClearSERP's paid platform takes it further by analyzing the actual search results for each keyword and scoring how beatable they are.

When you run a full analysis on ClearSERP, the platform fetches the top 10 Google results for each keyword and inspects every ranking page for weaknesses: low domain authority, slow page speed, outdated content, missing HTTPS, high spam scores, broken pages, and more. It detects 16 different types of weaknesses across four categories, then combines them into a Keyword Score (0–100) that tells you at a glance how much opportunity exists.

A high Keyword Score means the current top 10 has real openings you can exploit. A low score means the results are dominated by authoritative, well-optimized pages with few weak spots. This is the difference between guessing which keywords you might rank for and knowing which ones have genuine opportunity.

Other features in the paid platform include:

• Bulk analysis of up to 1,000 keywords at once, each with full SERP weakness detection and scoring.
• Domain and competitor research to discover what keywords any website ranks for, along with positions and estimated traffic.
• Keyword gap analysis that compares two domains and finds keywords your competitor ranks for that you do not.
• Collections for organizing and saving your best keyword finds, with the ability to re-analyze them later as SERPs change.
