Semantic Markup, Section 508- Accessibility, and Search Engine Optimization

Semmantic Markup

Semantic markup can be defined as the use of a markup language to show information about the meaning of each element in a document. This information is shown through proper selection of markup elements and to maintain complete separation between the markeup and the visual presention of the elements in the document.

Semantics work hand and hand with SEO because search engines use semantic markup in order understand what a website purpose so they can present information about the site when someone searches for the site. Semantics also work hand and hand with accessibility to make sure webiste websires are accessible to all vistoitors.Semantic Markup is very important for making websits acessibie and optimized on web searches

Search Engine Optimization

SEO is the method of strategies, techniques,and taticsused to increase the amount ofvistors to a website.Google's guidelines require 'honest markup' and their web crawlers now detect abuses such as hiding tags under images or text the same color as the background. The best way to get top placement is for one, use semantic markup. Since Google's web crawlers can see abuse of tags, not using semantics will only hinder you results. Using semantic tags makes your website more friendly to all people, whether disabled or not, and therefore make it more likely to show up higher in the search.
