Welcome to the Q&A Forum

You generally want to have the tag at the top of the page, above the content paragraph. **Keep it close in relation to the content that is below it also for correlation, **Personally, I'd have it below the banner for that context and keeping a better user experience. Typically, you don't place an inside the HEADER of the page, but rather the of the site. The Title tag would be in the header. As long as there is only one H1 tag it doesn't really matter where it is as you are calling it the most important title. Use H2-4 for all the other headings on the page and it will be read that way. As long as the H1 is concise and to the point relating to the page in question above or below makes no difference. Bruce Clay has a decent view on this and is usually pretty accurate on such things.
