Headings
The heading element briefly describes the subject of the section it introduces.
Heading elements go from H1 to H6 with the lower numbered headings being most important. You should only
use a single H1 element on each page, and may want to use multiple other heading elements to structure a
document. An H1 element source would look like:
<h1>Your Topic</h1>
Heading elements may be styled using CSS. Many content management systems place the same content in the
main page heading and the page title, although in many cases it may be preferential to mix them up if possible.

Hijacking
Making a search engine believe that another website exists at your URL. Typically done using techniques such
as a 302 redirect or meta refresh.
Home Page
The main page on your website, which is largely responsible for helping develop your brand and setting up the
navigational schemes that will be used to help users and search engines navigate your website.
As far as SEO goes, a home page is typically going to be one of the easier pages to rank for some of your more
competitive terms, largely because it is easy to build links at a home page. You should ensure your homepage
stays focused and reinforces your brand though, and do not assume that most of your visitors will come to your
site via the home page. If your site is well structured many pages on your site will likely be far more popular and
rank better than your home page for relevant queries.
