Primary Density
Primary keyword density should be around 1%. This means for every 100 words, 1 should be your main keyword. It's the optimal point to rank without seeming like spam.
Ideal Density
~1%. For a 1500-word article, include your keyword 12-18 times.
Keyword Stuffing
Avoid exceeding 2%. Google penalizes content that seems artificially manipulated.
Secondary Density
Secondary keywords complement your main topic. Their density should be around 0.65%, to not compete with your main keyword.
Secondary Density
0.65%. Alternatives and variations of your main topic.
Header Structure (H1-H6)
Headers give hierarchical structure to your content. Never skip levels: don't go from H1 to H3. The correct structure is H1 → H2 → H3 → H4.
Common Error
Using H1 for the title and directly H3 in subtitles. Skip H2.
LSI in Subtitles
LSI (Latent Semantic Indexing) words are semantically related terms. Include them naturally in subtitles to expand your topical coverage.
Minimum recommended
10 LSI entities distributed in the article.
Internal and External Links
High-authority links (.edu, .gov, recognized media) pass "link juice" and signal well-researched content.
Recommended links
Educational institutions (.edu), government (.gov), Wikipedia, recognized media outlets.
Multimedia Richness and Alt Text
Images enrich the experience. For image SEO, include your keyword in at least one ALT attribute of an image.
Alt example
alt="Digital marketing chart for SMEs" (includes keyword)
