I have a question of when I should use H2 and H3 headings. Specifically the question is about how I should organize my blogs and which headings should be used. Mistakenly, I used H1 highlighting each topic in a paragraph but H1 should be used once which it is in a title. The question is Can I or Should I use h2 for better organization and SEO? If my question is still confusing, I will ask more specifically:
Let's say I have 3 blogs about How to Look Classy:
How to Look Classy part 1
How to look Classy part 2 - White color
How to Look Classy part 3 - Colors
They are broken into 3 parts because the blogs are lengthy. So where H1 is used? In a title of each blog?
In the body of the blog I used "paragraph" which is correct but each blogs is broken different sections with a heading that has a separate point, so what I should use there? As I said, for the moment it's H1 which is wrong. Should I use H2?
