SHORT ANSWER

The Zuhio Keyword Count Checker is a free web tool with two boxes: one for your full list of target keywords and one for your entire blog. You paste both, click Check Keywords, and it tells you how many times each keyword appears in the text, so you can confirm every assigned keyword made it in before you publish.

MY VERDICT

Bookmark it, keep a backup

Here is the situation this tool is built for. You finish a blog. The brief that came with it had a list of keywords you were told to include, sometimes ten of them, sometimes twenty. Before you submit, you have to confirm every single one is actually in the draft. The slow way is to open Find, type a keyword, check, clear it, type the next one, and repeat fifteen times. It works, but it is dull and easy to fumble.

Zuhio's Keyword Count Checker promises to collapse that whole routine into one click. Paste the keyword list, paste the blog, and get a count for every keyword at once. That promise is exactly why I wanted to test it properly rather than just describe the buttons. So I grabbed a finished blog, a DaVinci AI review, and a real keyword list and put it through its paces. I also read every independent review I could find, so you get more than one person's experience.

What the Zuhio Keyword Count Checker is

The Zuhio Keyword Count Checker is a free online utility that lives inside Zuhio under the Keyword Count Checker tab. When I used it, there was no sign-up wall and no install. You land on the page and the tool is right there.

The layout is the first thing worth getting right, because most other write-ups describe a different tool. There are two text boxes stacked on top of each other:

  • The top box says “Paste all the MM keywords at once.” This is where your whole keyword list goes.
  • The bottom box says “Paste the entire blog here.” This is where the full article goes.

Under both sits a single blue Check Keywords button, and below that a short tutorial video. That is the entire interface. No dashboard, no settings, no export. It does one job, which is the whole point.

Quick facts from my test

FEATUREWHAT I FOUND
CostFree, no paywall or usage cap shown
AccountNot required
InputTwo boxes: keyword list on top, full blog text below
URL analysisNone. You paste text; it cannot fetch a live page
OutputA count next to each keyword
MatchingExact phrase, so word order matters
Export / highlightingNeither. You read the counts on screen
Error messagesNone. If something goes wrong, nothing happens

Why other guides describe a different tool

If you have read other articles about this checker, you have probably seen it described as a classic single-keyword density tool: type one keyword, get a count and a percentage. A few go further and mention competitor URL analysis. That does not match what I used, and I am not the only one who noticed.

One independent tester at Mostly Blogging went looking for a URL field on the live tool in July 2026 and found none, only pasted text and keywords. The same reviewer pointed out that several glowing write-ups appeared within weeks of each other, used similar wording, and never showed a screenshot of actual results. Another review noted there is no single, clearly established official Zuhio presence, and there is at least one separate website using the Zuhio Keyword Count Checker name on a different domain.

WHAT THIS MEANS FOR YOU

Trust the page in front of you, not the feature lists in other articles. Check the address bar before you paste anything, and judge the tool by what it actually shows. That is also why I have included my own screenshots in this review.

How it differs from a normal density checker

This is the bit other guides miss. A classic keyword density checker takes one keyword and one piece of text and gives you a percentage. Zuhio is built around the opposite habit. The top box literally asks for the MM keywords, plural, all at once.

That changes what the tool is good at. It is less of a density calculator and more of a checklist verifier. The question it answers is not “is my density 1.4 percent,” it is “did all twelve of my required keywords actually make it into the draft, and which ones are still missing.”

My step-by-step test

I wanted a real test, not a throwaway one. So I used an actual finished article and an actual keyword list, the same way a working writer would on submission day.

I opened the tool

Straight to the Keyword Count Checker page. No account, no setup, both boxes empty and waiting.

MY OBSERVATION

I open a tool like this on submission day, when I am already short on patience, so the lack of friction mattered to me. No login screen, no pop-up, no “create an account to continue.” Two labelled boxes and a button. I knew exactly what to do without watching the tutorial video underneath, which is a good sign for any tool that claims to be simple.

Screenshot 1: The Zuhio Keyword Count Checker page exactly as it loaded for me, two boxes and a Check Keywords button.

I pasted the keyword list into the top box

My ten must-mention keywords:  davinci ai ,  ai image generator ,  ai video generator ,  multi model ai ,  sora alternative ,  veo alternative ,  midjourney alternative ,  kling ai ,  ai content creation ,  generative ai app 

MY OBSERVATION

This is where I quietly made my first mistake, though I did not know it yet. I copied the list straight out of my brief, bullet points and all, and the box swallowed it without any complaint. There was no warning, no formatting hint, nothing telling me the bullets might be a problem. At the time it looked completely fine, which is exactly why the issue caught me out later.

Then i pasted the whole blog into the bottom box

The complete DaVinci AI review, intro to conclusion, a couple of thousand words of it.

MY OBSERVATION

I liked that I could drop the entire article in one go. No character limit warning popped up and the full two thousand words went in without lag. A lot of small tools choke on a long paste or ask you to do it section by section, so being able to load the whole blog at once felt right for the job it is meant to do.

Screenshot 2: My keyword list in the top box and the full DaVinci AI blog in the bottom box, ready to check.

I clicked Check Keywords

And then I waited for the counts to appear.

]MY OBSERVATION

This is the moment it let me down on the first try. I expected an instant list of counts. Instead the page just sat there, no spinner, no error, no movement at all. I will be honest about my reaction: my first thought was that the tool was broken, not that my own paste was the cause. That assumption cost me a reload and a re-paste before I worked out what was actually going on, which I cover in the next two sections.

If everything had gone smoothly, the result I expected is a list like the one below, where each keyword sits next to the number of times it shows up in the blog.

An example of the read-out the tool is meant to give. The three “alternative” phrases at 0 are the must-mentions I still needed to write in.

WHY THIS READ-OUT IS USEFUL

The blog mentioned Sora, Veo and Midjourney by name, but never the exact phrases “sora alternative,” “veo alternative” or “midjourney alternative.” A count of 0 next to those is the tool quietly telling me those exact must-mentions are not in yet. That is the moment the keyword counter earns its place in the workflow.

Check Keywords did not work at first

Here is the honest bit. On my first run, I pasted both boxes, clicked Check Keywords, and nothing happened. No counts, no error message, no loading spinner. The page just sat there.

My first guess was a connection hiccup, so I reloaded the page, pasted the keyword list and the blog again, and clicked Check Keywords a second time. Same result. Still nothing. No results panel appeared at all.

That is frustrating in the moment, but it turned out to be fixable, and the reason is worth knowing before you blame the tool.

Why it stalls and how to solve it

The thing that tripped me up was the format of the keyword list, not the tool being broken. I had copied my keywords straight out of the brief, and they came across as a bulleted list, each line starting with a bullet symbol.

WHAT I PASTED

● davinci ai● ai image generator● ai video generator

WHAT WORKS

davinci aiai image generatorai video generator

Those leading bullet characters (the little dots) get pasted in as real text. A simple counter can choke on them or read “● davinci ai” as the keyword, which never matches the clean phrase in your blog. Strip the bullets out and paste the keywords as plain lines, and the check behaves.

Why a bullet breaks a list checker

A tool like this has to split your top box into separate keywords, usually on line breaks or commas. Once a bullet leaves your doc, it is no longer formatting. It becomes a real character, often followed by a tab or a special space. The checker either trips over those unexpected characters or ends up searching for a keyword that starts with a dot. I cannot see Zuhio's code, so treat this as an educated explanation rather than a confirmed one, but removing the bullets fixed the stall for me every time.

THE FIX THAT WORKED 

Paste your keywords as a clean list with no bullet symbols, no numbering, no dashes in front. One keyword per line (or separated by commas) in plain text. Removing the dots from my list was what got the check to actually run.

BULLETS ARE NOT THE WHOLE STORY

When I compared notes with other testers, I found that at least one got the same silent non-response using a single, clean keyword across several browsers. So bullets were my cause, but they are not the only one. If your list is already clean and nothing happens, the problem may well be on the tool's side.

IF IT STILL WILL NOT RUN

Then it is likely a temporary issue on the tool's side rather than anything you did. Come back a little later, or use the Google Sheets checker in the alternatives section as a fallback for that submission. A tool doing nothing is annoying, but it does not mean your draft is wrong.

Exact-match traps that cause surprise zeros

Zuhio counts exact phrases. That makes it precise, but it also means tiny, sometimes invisible differences between your brief and your draft can produce a zero even when you are sure the keyword is there. These are the ones worth knowing:

TRAPWHAT IT LOOKS LIKEHOW TO FIX IT
Curly vs straight apostrophesThe brief says beginner's, your doc auto-corrects to beginner’sMake them match, or leave the apostrophe out of the keyword
Invisible special spacesText copied from Docs, Word or web pages can carry a non-breaking space that looks identical to a normal onePaste as plain text with Ctrl+Shift+V (Cmd+Shift+V on Mac)
Hyphens and dashes“multi-model ai” in the draft, “multi model ai” in the briefMatch the brief exactly, or ask your editor which form counts
Plurals and verb forms“ai image generators” vs “ai image generator”Depends on how the tool matches; run the 30-second test below
Spelling and spacing“Da Vinci AI” vs “davinci ai”, “e-commerce” vs “ecommerce”Use the form in the brief; flag it if it clashes with the brand's spelling
Typos in the briefThe brief itself has a typo, so your correct spelling scores 0Tell your editor rather than copying the typo into the article

THE 30-SECOND TEST

Before trusting the numbers on a big article, paste three keywords into the top box and a two-line dummy text into the bottom one, something like: “The DaVinci AI app is an AI image generator. It beats other ai image generators.” The counts tell you right away whether capital letters matter and whether plurals count. Once you know the rules, the zeros on your real draft make sense.

How to use the tool correctly

Once you know about the formatting trap, the workflow is genuinely quick. Here is the clean version.

  1. Finish writing first - Write the blog naturally for a human reader. Do not write to hit keyword counts, that always reads stiff. Check the counts afterwards.
  2. Clean up your keyword list - Take the keywords from your brief and strip any bullets, numbers or dashes. Leave one clean keyword per line.
  3. Paste the list into the top box - The “Paste all the MM keywords at once” box. All of them together.
  4. Paste the full blog into the bottom box - The whole thing, headings and all, so nothing is missed. Use plain-text paste (Ctrl+Shift+V, or Cmd+Shift+V on Mac).
  5. Click Check Keywords and read the counts - Scan for any keyword sitting at 0. Those are your must-mentions to add.
  6. Fix, then recheck - Work the missing keywords in naturally, paste the updated blog back, and run it once more to confirm.

How to read your keyword count results

The tool gives you numbers. It does not tell you whether those numbers are good. That judgment is on you, so here is how I read them.

Any keyword at 0 is the priority

A zero means a required keyword is missing entirely. That is the single most useful thing the tool surfaces. Add those first, in a place where they read naturally, not jammed into a random sentence.

Your primary keyword should lead, but not dominate

It is fine for the main keyword to show the highest count. What you do not want is a number so high the phrase appears in nearly every paragraph. If your primary keyword is sitting far above everything else and the writing feels repetitive, swap a few instances for natural variations.

Density is a sanity check, not a target

The common working range people quote is roughly 1 to 2 percent for a primary keyword, meaning about 10 to 20 mentions in a 1,000-word article. Treat that as a comfort zone, not a rule. A genuinely useful article that covers its topic well often ranks without hitting any exact figure, and forcing a number usually hurts the writing.

WORK OUT DENSITY YOURSELF IN 10 SECONDS

Density = (keyword count ÷ total words) × 100. In the example read-out above, 14 mentions in roughly 2,000 words works out to about 0.7 percent. That is under the usual rule of thumb, yet the article still reads as clearly about DaVinci AI. Which is exactly why I treat density as a sanity check and nothing more.

Placement beats raw count

Where a keyword appears matters more than how many times. Before you add extra mentions, make sure your primary keyword sits in the title, the H1, the first hundred words or so, at least one subheading, and the meta description. Google's own spam policies list keyword stuffing as a problem, so piling on mentions to raise a number can work against you.

ONE THING TO REMEMBER

Zuhio counts exact phrases. “sora alternative” will not be counted just because the blog says “Sora.” If a must-mention is a specific phrase, the words have to appear in that order for the count to register. That is a feature, not a bug, but it explains a lot of surprise zeros.

Real user feedback: what other testers report

One test is one data point, so I went looking for other people's experiences. At the time of writing I could not find meaningful discussion threads or review-platform listings for this tool, so the feedback below comes from people who ran their own tests and published them. I have summarised each in my own words and linked the originals so you can read the full take.

Mostly Blogging   NEGATIVE 

Usama Dilawar · tested July 2026

Pasted a roughly 1,200-word article with a single keyword, then retried with a shorter sample, another keyword and a second browser. Got no count, no error and no spinner every time. Also flagged that the site gives little sign of active development and that some reviews describe features the live tool does not have. Recommended SEO Review Tools, SmallSEOTools, Rank Math or a manual Ctrl+F count instead.

AI SEO Tips   POSITIVE · 7/10 

Noman Sarwar · used across several articles

Found it handy for spotting when a phrase was overused in a competitive piece. The bigger lesson was that chasing a “perfect” density made the writing worse, so they now lean on natural variations and treat the tool as a balance check rather than a strategy.

Emerson FRP Tools   VERY POSITIVE 

Head-to-head comparison with other counters

Praised the speed and simplicity, and said results were consistent across their tests, with the caveat that accuracy depends on clean input. Rated it highly for quick draft checks, while noting Yoast is still the all-in-one pick for WordPress users.

Trendify Magazine   MIXED 

2026 features & limitations review

Noted that some sources describe the tool working normally, while at least one test in July 2026 found the main checker not working as expected. Concluded it is designed for keyword checks but that reliability is worth confirming.

Expand Magazine   CAUTIOUS 

Features, benefits and safety overview

Highlighted conflicting accounts about both reliability and which site is the official one, and advised against pasting sensitive or confidential material into an unfamiliar online text tool unless you are comfortable with its privacy practices.

The patterns I noticed

  1. The silent failure is real, and it is not just me - The most common complaint is exactly what I hit: click the button, nothing happens. Because at least one tester saw it with a single clean keyword, bullets explain some stalls, not all of them.
  2. Clean input keeps coming up - The testers who got good results tend to mention clean input, which lines up with my bullet discovery.
  3. Praise is about speed, complaints are about trust - Fans like the zero setup and one-click speed. Critics focus on reliability, the lack of error messages, and how little is published about the tool and its owner.
  4. Feature descriptions conflict - Some articles describe URL analysis or density readouts that do not match the two-box tool. Screenshots are the quickest way to tell a real test from a rewritten pitch.

Pros and cons

What I liked

Checks a whole keyword list in one click

Free, with no sign-up or install

Took a full 2,000-word paste without lag

So simple you don't need the tutorial

Exact matching catches missing must-mentions precisely

What let it down

Fails silently, with no error message to guide you

Stalled on a bulleted keyword list

No export and no highlighting of where keywords appear

Paste only, no URL checks

Mixed reliability reports and little published information about data handling

Who should use this tool

This is not a tool everyone needs every day. It earns its place for a specific kind of work.

Writers working from briefs

If a client or editor hands you a must-mention list, this is the fastest way to confirm you hit all of it before submitting.

Freelancers juggling several articles

A quick paste-and-check beats eyeballing a long draft for fifteen separate phrases.

SEO and content leads doing final review

A fast sanity pass on whether assigned keywords landed, without opening a full platform.

Anyone newer to SEO

No setup and no jargon. Paste, click, read the counts.

If your job is keyword research, rank tracking or backlinks, this is not that tool, and it does not pretend to be.

The best Zuhio Keyword Count Checker alternatives

Zuhio's one real trick is checking a whole list at once. Most free alternatives are single-keyword density checkers, so I have grouped these by the job you actually need done.

SAME JOB - Check a whole keyword list at once

DIY Google Sheets checker (my go-to backup)

Free, private, and it never stalls. It takes five minutes to set up once, then you reuse it for every brief. It also works in Excel.

1.  Type “Keyword” in A1, then one keyword per row from A2 down.

2.  Click D1 and paste your whole blog. It will spread down column D, one paragraph per row, which is fine.

3.  Paste the formula below into B2 and drag it down next to your keywords.

4.  Optional: add conditional formatting so any cell equal to 0 turns red.

=IF(A2="","",(LEN(LOWER(TEXTJOIN(" ",TRUE,D:D)))-LEN(SUBSTITUTE(LOWER(TEXTJOIN(" ",TRUE,D:D)),LOWER(TRIM(A2)),"")))/LEN(TRIM(A2)))

It ignores capital letters and counts text inside longer words, so “ai image generator” also counts inside “ai image generators.” That makes it slightly more lenient than an exact-match tool. Sheets caps the joined text at 50,000 characters, which is plenty for a typical blog.

The honest read: Zuhio is not competing with Ahrefs. It is competing with the tedium of Ctrl+F. For checking a list of required keywords against a finished draft, it is the fastest free option on that list, when it runs. The Sheets checker is the one I keep beside it for the days it doesn't.

SAFETY

Is it safe to paste client work into it?

Zuhio asks for no account, which limits your exposure. But independent reviewers say they could not find a published explanation of how pasted text is handled or stored. My rule is simple: published or near-final blog copy is fine. Anything under an NDA, an embargoed launch, or a confidential client draft goes through the Google Sheets method instead, where the text stays in your own account.

MY FINAL VERDICT

A useful one-trick tool, with a backup close by

Here is where I land after running a real article through it. I went in expecting either a slick tool or a useless one, and it turned out to be neither. It is a small, single-purpose utility that does one thing I genuinely have to do on every briefed article: confirm that a list of must-mention keywords actually made it into my draft. When my input was clean, it did that faster than the manual routine I would otherwise grind through, and for free.

The rocky start is part of my honest take. That first “I clicked Check and nothing happened” moment nearly made me write the tool off, and I suspect it is why a lot of people give up on it. In my case the cause was my own bulleted paste, and once I stripped the bullets it ran every time. Reading other testers' experiences tempered my view a little, though: some hit the same wall with perfectly clean input, so I would not make it the only check in your process.

So would I use it again? Yes, and I already have. It now sits as the last step before I submit a briefed piece, with the Google Sheets checker as my fallback. Paste your keywords as a clean list rather than bullets, treat the counts as a checklist instead of a target, and keep your own judgment about whether the writing reads well. Do that and it quietly saves you the fifteen rounds of Ctrl+F I used to do by hand.
