WordPress h1 tags and Title.

But in Blogger Blog, both title and h1 tag will be the same. So we can say here that we already implement the h1 tags when we add the title. This is all about the h1 heading tag for WordPress and Blogger.
Placement of Subheading h2.
There is a hierarchy of heading tags h1, h2, h3, h4, and so on tags. That means when h1 is the most senior after that, its child is h2.

You can understand that the h1 tag that includes all parts in the red quadrilateral is the whole family in the above structure. h2 mean son of h1, and what is inside we write using h2 tag will be the name of that son. There can be only one h1 tag, and multiple h2 heading tags are possible for the whole family.
Use of h3 tags
Heading h3 tags are the children of the h2 family, but here you’ve to keep in mind that only one h2 is allowed in this family, and it will be a mistake if you’re adding the second h2 for the same family. To understand this, let’s take an example.

In the above post-term, “Pollution” is the main heading h1 or the family tree’s head. The names of its subheading can be explained as explained above. And then, we can create a family of each sub-heading h2. Please keep in mind that you can’t jump the tags like h1>h3 this will be the wrong way to do things. You must follow the hierarchy h1>h2>h3>h4.
