Frequently Asked Questions
Technical and usage details for Word & Character Counter
Is my written text stored, logged, or sent to any server?
No. All text parsing, word metrics, sentence tokenization, and keyword frequency calculations happen 100% locally inside your web browser memory. Zero keystrokes or text contents are ever uploaded or transmitted.
How is estimated reading and speaking time calculated?
Estimated reading time is computed using the scientific benchmark of 200 words per minute (WPM) for silent reading. Speaking or presentation time is calculated at 130 words per minute (WPM), the standard cadence for natural conversational speech.
What is the optimal keyword density for SEO content?
SEO best practices recommend maintaining primary keyword density between 1.0% and 2.5%. Exceeding 3.0% often triggers search engine keyword-stuffing penalties, whereas staying below 0.5% may fail to establish topical relevance.
What constitutes a "word" in this counter?
A word is defined as any continuous sequence of non-whitespace characters separated by standard whitespace boundaries (spaces, tabs, newlines). Hyphenated words are counted as a single word unless separated by spaces.
What are the current social media character limits?
X (formerly Twitter) allows 280 characters for standard accounts, LinkedIn posts permit up to 3,000 characters, Instagram captions support up to 2,200 characters, and YouTube descriptions allow up to 5,000 characters.
How does sentence and paragraph detection work?
Sentences are parsed using terminal punctuation delimiters (. ! ?), excluding common abbreviation dots where possible. Paragraphs are recognized by continuous line-break sequences (\n+).
