Identify and count common stop words in your content.
Words like "the," "is," "and," "of" you use them in nearly every sentence you write, and you almost never notice you're doing it. That's exactly what a stop word is: a common word that holds a sentence together grammatically but doesn't carry much meaning on its own. A stop words counter scans your text, flags every one of these, and tells you how many there are and what percentage of your total word count they make up.
It's one of those tools that sounds almost too simple to matter, until you actually see the number. I ran a paragraph I'd written through something like this once expecting maybe 20%, and it came back closer to 45%. Not wrong, exactly stop words are unavoidable in normal writing but it was a useful reality check on just how much of my word count wasn't doing any real work.
There's no single universal list, but most versions include the obvious suspects articles like "a," "an," "the," prepositions like "in," "on," "at," "with," conjunctions like "and," "but," "or," and a handful of common verbs and pronouns like "is," "was," "it," "this." None of these are bad words to use. English sentences don't function without them. The point of tracking them isn't to eliminate them that would make writing sound stilted and weird, it's just to understand how much of your text they're occupying.
Search engines and older text-processing systems historically ignored stop words when indexing content, since a word like "the" appearing 200 times in an article tells a search algorithm basically nothing about what the article is actually about. That's changed a lot as search engines have gotten better at understanding full context and phrasing rather than just isolated keywords, but the underlying idea still shows up in how people think about writing tight, focused copy especially in places where every word counts more than usual.
Titles and headings are a good example. A page title like "The Best Way to Learn How to Cook for Beginners" is stuffed with stop words that add length without adding meaning. Trim it to "Learn to Cook: A Beginner's Guide" and you've cut the fluff while keeping the actual message intact plus it fits better within the character limits search engines display before truncating a title anyway.
Paste your text in, and it checks every word against a stop word list, tallying up matches as it goes. You get three numbers back your total word count, how many of those were stop words, and the percentage that represents. There's also an option to see the actual list of stop words it caught, which is genuinely useful if you want to look at exactly which ones are showing up most, rather than just trusting the overall percentage.
SEO writers use it when reviewing titles, meta descriptions, and headings specifically, since those spots benefit the most from tight, deliberate wording. There's limited space, and every stop word eating into that space is one less word doing actual work. Checking the stop word percentage on a headline draft can be a quick nudge toward tightening it up.
Content editors sometimes use it more broadly across full articles, not to hit some target percentage, but to catch pieces that feel unusually padded or wordy. A high stop word ratio spread across an entire article can sometimes point to sentences that are longer and more roundabout than they need to be "in order to achieve this" instead of just "to achieve this," that kind of thing.
Writers focused on concise, punchy copy ad writers, headline writers, anyone working with tight character limits use it as a filter to spot where trimming would help without changing meaning.
A high stop word percentage isn't automatically a problem. Natural writing includes plenty of them, and forcing your percentage down artificially usually makes sentences read awkwardly, almost telegram-style. This tool works best as a diagnostic, not a target to chase blindly.
Paste your text, see the breakdown immediately. No account required, no cap on text length, and the stop word list stays visible if you want to dig into specifics rather than just the summary numbers.
