Free Keyword Idea Generator & Density Checker
By Buli Goswami · Last updated: 14 September 2026
I built this tool because I got tired of jumping between three different websites just to plan one article. Here you can brainstorm keyword ideas and check your draft for repetition — all on one page, without signing up. Both jobs normally need two separate tools. This page does both, for free, and it tells you honestly what the numbers can and cannot do.

📘 The honest guide: how to use these numbers without fooling yourself
Most keyword tools online hand you a big confident number and let you believe it came straight from Google. It usually did not. So before we go any further, here is the plain truth about what this page does — and what it does not do.
What this tool actually does
This is a Keyword Idea Generator & Density Checker — not a full keyword research database. When you type a topic, the script on this page takes your words and combines them with common search patterns like “best”, “for beginners”, “checklist”, “guide”, and “vs”. It then assigns each phrase an estimated volume, an estimated difficulty score, and an estimated CPC. Those three numbers are calculated locally in your browser using a fixed formula.
That means two things. First, the same keyword and country will always give you the same result, which is handy for comparing. Second, the numbers are not live Google data. They are a rough yardstick, nothing more. If you are planning a serious campaign, take the shortlist from here and verify it somewhere with real data.
What each column really tells you
- Estimated volume: roughly how many people might search for that phrase in a month. Higher means more potential visitors, but also usually more competition. Treat it as “big, medium, small” rather than an exact count.
- Estimated difficulty: a 0–100 style score. Green (low) is generally easier for a newer site to compete for. Orange is a fair fight. Red means you will likely need stronger content, better internal links, and time.
- Estimated CPC: what advertisers might pay per click. A higher CPC often hints that the topic has commercial value — useful if you plan to monetise, less useful if you just want readers.
- Long-tail phrases: anything with three or more words. These usually have lower competition and bring visitors who already know what they want. For a new blog, long-tail is where most of your early traffic tends to come from.
How to use the tool, step by step
- Type a broad topic from your niche. Not too narrow — “coffee” works better than “best Ethiopian single origin coffee bean”.
- Pick a country if your audience is mostly in one place. It shifts the estimate range a little.
- Click “Check Keywords” and read down the list.
- Shortlist two or three phrases that look like a good mix of decent volume and low difficulty.
- Paste your draft into the density box on the right and click “Analyze density”.
- Read the report honestly. If your main phrase is the top result, good. If a filler word is topping the list, that is normal — the checker ignores the usual stop words automatically.
- Rewrite anything that feels repetitive — not because a number told you to, but because it reads badly.
About keyword density — the part most tools get wrong
You have probably read that you should keep your keyword at exactly 1–3%. That advice has been copied around the internet for over a decade, and it is not a Google rule. Google has never published a target percentage. Modern search systems look at meaning, context, and whether your page actually answers the question — not at whether a word appears 2.4% of the time.
So what is density good for? It is a repetition check. It helps you notice when you have said the same thing fifteen times in a 600-word post. That is a writing problem, not an SEO formula problem.
A practical way to use it:
- If your main phrase is somewhere in the top few results, you are probably covering the topic.
- If your main phrase does not appear at all, you may have drifted off-topic.
- If one content word takes up a very large share of the text, read it out loud. If it sounds robotic, rewrite it.
- If it reads naturally, stop worrying about the percentage.
In short: write for the person reading. Use the numbers as a mirror, not a rulebook.
Why I built this as a free tool
When I started blogging, every keyword tool I found either wanted a credit card, capped me at three searches a day, or buried the useful part behind a paywall. I did not need enterprise data. I needed a quick way to brainstorm and a quick way to check my draft before hitting publish.
So this page does exactly that, and nothing more. It is free to use and does not ask you to sign up. If it saves you ten minutes per article, it has done its job.
Best practices that actually still work
- Put your main phrase in the title and H1. Not because of a formula, but because readers and search engines both need to know what the page is about in the first second.
- Answer the question early. Give the short answer in the first 100 words, then expand. This matches how people actually read.
- Use subheadings that ask real questions. “How much does it cost?” beats “Pricing considerations”.
- Cover the topic, not the keyword. Write about the related things a reader would want to know. This naturally brings in variations without stuffing.
- Link to your own related posts. A few honest internal links help readers stay on your site and help search engines understand your structure.
- Write alt text for images. Describe what the image shows. That is it.
- Check your draft before publishing. A grammar pass and a repetition pass catch most problems.
- Be patient. Most pages take weeks or months to settle. That is normal.
Mistakes I made so you do not have to
- Chasing big keywords too early. My first posts targeted phrases with huge volume. They never got much traction. Small, specific phrases worked much faster.
- Writing for the algorithm. Posts I wrote to “hit a density” read terribly and got no shares. Posts I wrote to explain something clearly did much better.
- Ignoring search intent. If someone searches “how to fix X”, they want steps, not a history of X.
- Publishing and forgetting. Updating an old post often beats writing a brand new one.
❓ Frequently asked questions
Yes. The tool is free to use and does not ask for a sign-up or credit card.
No. They are simulated estimates created in your browser to help you compare keyword ideas. They are not official Google Keyword Planner figures.
You can pick a country to change the estimate range. Treat the result as a rough comparison, not confirmed local search data.
Plan keywords before every new article, and review your main pages every three to six months.
Keyword density is only one basic measurement. There is no universal percentage that guarantees better visibility. Write naturally for readers.
The tool applies a country multiplier so you can compare markets. It is a comparison aid, not a measurement of real demand.
