Free Keyword Research Tool

Research keywords before you write, not after you fail

Most content that never gets seen was doomed from day one: a keyword nobody searches for, or one where the competition is market giants. Keyword research means understanding, before you write a single word, exactly what phrase your target audience types and how hard it is to compete for.

  • No sign-up needed
  • Topic clustering
  • Real search volume, CPC & competition
  • Honest data, no fake numbers

Search Volume, CPC & Competition for One Keyword

A suggested keyword count alone isn't enough; you need to know how many people actually search for it (monthly search volume), what a click costs in Google Ads for it (CPC, an indirect signal of the keyword's commercial value), and whether ad competition for it is low or high. Try one keyword right here, free.

What Is Keyword Research, and Why Is It SEO's Most Profitable Step?

Keyword research means finding the exact phrases your target audience searches on Google, and measuring two things about each one: how many people search for it (search volume) and how hard it is to reach page one for it (keyword difficulty). This step is also called "keyword research" (obviously), and the common mistake is underrating it and jumping straight to writing.

Say you run an online kitchenware store. You could spend months writing an article for "kitchenware," a generic keyword thousands of big stores have competed for over years, or put that same energy into "stainless steel pot for gas stoves," which has far less competition and whose searcher has purchase intent right at that moment. The difference between these two decisions is the difference between content that brings customers for years and content that gathers dust on Google's tenth page. Keyword research makes exactly this choice data-driven for you, not a guess.

A point rarely mentioned: the ultimate goal isn't one keyword, it's a topic cluster. Someone searching "stainless steel pot" probably also has questions later about "stainless steel vs. Teflon" or "pot set prices." If you look at this cluster together, instead of one scattered page, you build a content architecture that makes Google see you as the authority on that entire topic.

Step-by-Step Keyword Research With This Tool

We're not handing you theory here; this is the exact path our team walks every day with this same tool.

1

Start with a real seed

Not an abstract keyword, but something your real customer actually says. If you're not sure, start from your main product or service name.

2

Read the suggestion list, don't just scroll it

The tool above builds dozens of combinations: with "how to," "price," "best," and the alphabet. Every row is a different search intent.

3

Sort keywords by intent

Some phrases are informational (the user wants to learn), some are commercial (the user is close to buying). Each needs different content.

4

Save your output

With a free sign-up on the dashboard, every suggestion list is saved and you can later set up rank tracking and competitor monitoring for them too.

5

Write one page per cluster

Not one page for everything; several targeted pages that each answer exactly one search intent rank better in the long run.

Search Volume, Keyword Difficulty & User Intent, No Fake Stats

Many free online tools show a number for local-language keywords that even they don't trust. We'd rather be honest:

Search volume

An estimate based on international search-data providers; usually reliable for high-frequency phrases, but for very local or brand-new phrases we may show "—" instead; a fabricated number is worse than no number.

Keyword difficulty

Our formula is transparent: it measures the strength of page-one competitors, not a black box. A high number means tougher competitors, not that ranking is impossible, just that you should know what contest you're entering.

User intent (search intent)

The most important, least-measured metric. A simple trick: search the phrase itself on Google and see what kind of page dominates the top results, an article, a store, or a comparison. Write that same kind.

CPC and Ad Competition, a Signal Many Overlook

Search volume tells you "how many"; CPC and ad competition tell you "how much commercial value." These two numbers come from the Google Ads world, but they're very useful for organic keyword research too.

CPC is the average price advertisers pay per click on that keyword in Google Ads. If a keyword's CPC is high, say "corporate tax consulting" versus "what is a tax, definition," it means advertisers are willing to spend serious money on it, which usually signals strong purchase or commercial intent. Ranking organically for such a keyword is, in the long run, more valuable than ranking for a keyword with near-zero CPC, even if its search volume is lower.

Ad competition (low/medium/high) shows how many advertisers are bidding on the same keyword. This metric isn't directly "SEO difficulty," a keyword can have high ad competition and relatively low organic competition, or the reverse, but combining these two with keyword difficulty gives a truer picture of a keyword's value and difficulty than relying on one number alone.

An honest note on local data: the data provider we use for search volume, CPC, and competition currently has no numbers for the Iranian market specifically; not just us, no tool relying on this tier of international provider has that coverage. Instead of showing a fabricated number for local-language keywords, we honestly display "—" and explain it right next to the number; for keywords with international intent or other countries (selectable in the full "Search Volume & CPC" tool), you'll see real, current numbers. We'd rather you see a "—" and know exactly where you stand than make a bad call on a guessed number.

Local Language Is the Problem, Not a Technical Footnote

Most of the world's keyword research tools are built for English and just "translate" local languages. That's exactly where the problem starts:

Character-set variants. The same word typed with slightly different regional character forms looks identical to a human searcher, but some tools count them as two separate keywords and cut the real search volume in half.

Spacing and typing habits. A word written the "correct" way with proper spacing is one thing, but many users type it all run together instead. Both forms need to be captured in the analysis, or a large chunk of real searches falls through the cracks.

Phonetic/Latin-script typing. Some local users, especially in technical or branded searches, type using the Latin alphabet phonetically instead of native script. Ignoring this volume means ignoring a real slice of the market.

Our keyword suggestion tool works directly on real local search data, not a machine translation of an English tool; that's what makes its suggestions match how people actually type in the real world.

Frequently Asked Questions

Is the keyword suggestion tool really free to use?
Yes. Without signing up, you can search, see suggestions, and try one keyword in the search volume/CPC teaser. To save lists, keep history, and link to rank tracking, a free account is enough; RGB's free tier is permanent, not just a few trial days.
What's the difference between keyword research and getting ideas from competitors?
They complement each other. Keyword research shows exactly what users say; competitor analysis (explained on our "Google Competitor Analysis" page) shows what content they've built around those same words. It's best to look at both together.
What does it mean if no search volume number is shown for a keyword?
It means reliable data wasn't available to us for that specific phrase. Instead of guessing, we honestly show "—". The absence of a number doesn't mean the keyword is worthless, especially for very local or specialized phrases.
How many keywords are enough per page?
One main keyword and 2 to 4 related keywords from the same cluster, fitting naturally into the text; if you read the sentence aloud and it sounds natural, the density is right. There's no magic number, excessive, artificial keyword repetition (keyword stuffing) is itself penalized.
Does this tool also suggest phonetic/Latin-typed and typo variants?
The tool tries to cover the most common real search variants, but it's not a substitute for your own judgment; always also spend a few seconds manually trying a few different spellings of your target keyword on Google.
Are keyword suggestion results personalized?
Not based on your personal search history. The data you see is independent of your Google account or browser location, the same thing any other user sees.
How do I use these keywords in content without falling into keyword stuffing?
The main keyword in the H1, one or two mentions in the H2s, and the rest only where it naturally completes a sentence. If you read the sentence aloud and it sounds odd, you've stuffed it.
Can I export my keyword list?
In the dashboard, CSV export of saved lists is available so you can share them with your content team or in your content planning files.
