Heading tags are very important has they will tell Google Search engines (and other's search engines) what is the most important content on your Blog.
So far there are six .H tags ( .H1 .H2 .H3 .H4 .H5 .H6) and on Blogger your Blog posts have .H3
tags your Blog title .H1 tags and your widgets (gadgets) have .H2 but this ain't very SEO friendly and you can change that let's start by changing your blog posts .H3 tags to .H1 tags to higheir visibility on Google SEO.
