Define your homeschool niche and approach
Homeschooling is diverse: classical education, Charlotte Mason method, unschooling, school-at-home (structured curriculum), unit studies, eclectic homeschooling, faith-based homeschooling, homeschooling for specific learning differences (ADHD, dyslexia, gifted learners). The most-read homeschool blogs serve a specific community within this diversity rather than trying to represent all approaches.
Your niche should match your actual homeschool practice — the methods you use, the values that drive your educational choices, and the age range of your children (early years, elementary, middle school, high school).
Write the blog you wish had existed when you started.
