Content optimization tips
Primary keyword density should be 1–3%. Below 0.5% is too low, above 3% risks keyword stuffing.
Include your target keyword in the first 100 words and last paragraph.
Use LSI (related) keywords naturally throughout your content for topical authority.
Aim for a Flesch readability score of 60–80 for general web content.
Longer content (1500+ words) tends to rank better, but quality matters more than length.
Use varied sentence lengths. Mix short punchy sentences with longer explanatory ones.
Break up content with headings every 300–400 words for better scanability.
Higher lexical diversity (40%+) indicates richer, more engaging content.
