What is Keyword Density?
Keyword Density defines the percentage of times a specific phrase or word appears within a piece of textual content in comparison to the total word count. If you write a 1,000 word article and mention the phrase "Car Insurance" roughly 25 times, your density sits precisely at 2.5%.
Preventing SEO Keyword Stuffing
In the early days of Google search, marketers would simply copy-paste their target keyword 500 times at the bottom of a page to rank first. Modern Google Core algorithms aggressively penalize this practice (called keyword stuffing). Search engines prefer natural, semantic writing.
- Ideal Density: Modern SEO consensus suggests aiming for 1% to 2.5%.
- Danger Zone: Anything over 3.5% will potentially trigger spam filters, downranking your article entirely.
Ignoring Stop Words
By default, the English language is flooded with conjunctions and prepositions. If you do not filter out words like 'the', 'is', 'at', and 'on', they will entirely break the density metrics block. FreeTools utilizes a built-in Javascript semantic filter to strip these "Stop Words" out before calculating the final keyword ratios.
