H1,H2&H3 tags structer help!!!!

hi,
i am running a blog in which i am using heatmap pro 5 theme.In this theme i have put h1 tag to the blog tagline
which is “Get Easy Tips and Tricks”.And h2 tag to post titles as you can see in my blog at https://www.ezytricks.tk
Is my h1,h2,h3 tags structure is good or not? But i have read in many places that h1 tag should consist your keyword. And also Easy WP SEO plugin ask for keyword in h1 tag.
Please give me suggestions. Is putting h1 tag to post titles good? If i put h1 tags to post titles then in homepage total h1 tags become 3 because
i am showing 3 recent posts in home page.
answer in detail.
