How to read your density report

The analyzer ranks the top 15 meaningful words in your content by frequency, ignoring stop words. Your primary keyword should appear near the top of that list, sitting between 1% and 3% density. Anything above 3% is flagged, since over-optimization now hurts rankings more than it helps.

Why reading grade appears here

Keyword optimization and readability work together. A page stuffed with keywords usually reads badly, and difficult text drives visitors back to search results, which weakens the engagement signals that influence rankings. Checking both in one pass keeps content optimized and readable at the same time.

Density range explained

The range shows the spread between your least and most frequent top-15 keywords. A wide gap suggests one term dominates the page, which can look unnatural. A tighter spread usually indicates well-distributed, semantically rich content.

Frequently Asked Questions

Between 1% and 3% for your primary keyword. Modern search algorithms weigh semantic relevance and natural language far more than raw repetition, so higher density brings no benefit and carries risk.
Stop words like "the," "and," and "of" appear in every text and carry no topical meaning. Filtering them out reveals the keywords that actually define what your page is about.
