One of important aspects of search engines optimization is document structure. Text data of HTML page consists of headers of different level (there 6 header levels in HTML) and from the plain text content. To create good document structure you should use #h1, #h2, #h3, #h4, #h5, #h6 tags. It is quite obvious that a header of the corresponding level (1, 2, 3, 4, 5 or 6) will be created in each case. The lower the header level is the more important it is. Headers on the page should go from the lowest to the highest header level.<\/p>\n
