title and your can add few keywords in your title - its can help.
The title tag will appear in search engines as your document title.

<H1> to <H6> tags
The <h1> to <h6> tags define headers. <h1> defines the largest header. <h6> defines the smallest header.
Search engines see the text between this tag as more important.
