Why Keyword Density Still Matters for Modern SEO
While Google's search algorithms now evaluate topical authority through semantic natural language processing (NLP) rather than exact keyword repetition, keeping an eye on keyword density ensures your content remains focused without straying into "keyword stuffing" penalties. Aim for a primary keyword frequency between 1.0% and 2.5%.
Our word counter analyzes your text in real time as you type or paste. Words are calculated by identifying non-whitespace character clusters separated by spaces, tabs, or line breaks. Characters are counted using Unicode code points so multi-byte emojis and accented letters are accurately tracked.
Twitter/X allows 280 characters for standard users. Instagram captions allow up to 2,200 characters, though the first 125 characters appear before the '...more' truncation. TikTok video descriptions support up to 4,000 characters. LinkedIn posts allow up to 3,000 characters.
Reading time is calculated based on the average adult silent reading speed of 225 words per minute (WPM). Speaking time is based on standard conversational presentation speed of 130 words per minute.
For comprehensive organic search rankings, industry studies by HubSpot and Backlinko indicate that articles between 1,500 and 2,500 words tend to earn more backlinks, social shares, and top-3 Google rankings for competitive queries.
