Word Frequency Counter

Stop words are common words like "the," "a," "is," and "and" that appear frequently in all texts. Excluding them reveals more meaningful word patterns. Include them when analyzing total word distribution or studying writing style; exclude them when focusing on content topics and keywords.

By default, our counter treats words as case-insensitive, so "Hello" and "hello" count as the same word. This gives more accurate frequency counts. You can enable case-sensitive mode when capitalization differences matter for your analysis.

Word frequency shows whether your target keywords appear often enough for search engines to understand your content's topic. It also reveals if you're over-optimizing (keyword stuffing) which search engines penalize. Aim for natural keyword density between 1-3%.

Yes, paste multiple documents together to analyze combined frequency, or analyze each separately and export the data for comparison in a spreadsheet. This is useful for consistency checking across content or comparing your writing to competitors.

Natural writing follows Zipf's Law where a few words appear very often and most words appear rarely. If your distribution looks unusual—too flat or dominated by unexpected words—it may indicate writing that feels unnatural or needs revision.
