Common Mistakes to Avoid

⚠️

Obsessing over exact percentages

Solution: There's no magic number. 1-3% is a general guideline, but natural writing matters more than hitting exact targets.

⚠️

Ignoring keyword variations

Solution: Search engines understand synonyms. "SEO tips", "SEO advice", "search optimization" all contribute to ranking.

⚠️

Keyword stuffing to hit targets

Solution: Forcing keywords hurts readability and can trigger Google penalties. Write naturally, optimize second.
