If you hope to be ranked highly, you must help the web spiders achieve their goal. Web spiders read the content of your website and determine your search ranking based on this; however, they need a way to easily distinguish what your content is. You need to stress what about your site is important by creating a site map that allows a spider to grasp the hierarchy of your pages.
Make sure that your header tags are efficient. Headers are large at times. However, CSS can be used to alter the size. Headers are essential because search engines enjoy using them to rank sites. The most important aspects of your page, like the service or product you are offering, should be flagged with either H1 and/or H2 tags.
