Keyword Density Checker

In 2003, stuffing a keyword into a page 27 times worked. In 2026, it gets you penalized. Google's algorithm shifted years ago from term frequency to semantic understanding — it reads your page the way a human would and understands that "cheap flights to Paris" and "affordable Paris airfare" mean the same thing.

The right way to use a density checker today: make sure your target keyword appears naturally (usually 0.5–1.5% of total words), that you're not accidentally over-optimizing (anything above 3% starts to look manipulative to Google's spam classifiers), and that related terms show up too. If you're writing about "espresso machines" and the words "portafilter," "grind," "bar pressure," and "milk steamer" never appear, Google may not fully understand what your page is about.

Look at the top 10 words on your page. Your primary keyword should be in the top 5. If it's not, you probably haven't committed to the topic — either rewrite the intro to lead with it, or accept you're writing about something else. Look at the two-word and three-word phrases too. These "n-grams" are what modern search engines actually score against.

Then check the pages currently ranking for your target keyword. If they average 1.2% density and yours is 4%, cut back. If they're at 1% and you're at 0.2%, you're being too coy — mention the term more directly. The winners aren't at any magic number; they're at whatever feels natural for that topic.

Never rewrite a sentence just to force in a keyword. Every awkward "best cheap flights to Paris cheap" phrase is a small credibility hit for a reader and a small ranking risk with Google. Never hide keywords in the same-colored text as the background, in tiny fonts, or off-screen — this is called "hidden text" and is grounds for manual action. Never repeat the same anchor text on internal links to the same page (Google now treats this as manipulative). And don't obsess over any single keyword — modern SEO is about covering a topic thoroughly, not hitting one phrase X times.
