When it comes to SEO practices, HTML5 can be tricky because at this point it does not necessarily improve SEO in anyway. The reasons for this are because there has yet to be a browser released that has the capability of fully supporting the codes and features unique to HTML5.
To date, Google, the world's most widely used search engine, has done nothing to try and support HTML5 in relation to SEO use. HTML5 is SEO user friendly when it comes time to index a particular website.
In the case of any website that relies heavily on Flash, SEO is very beneficial to HTML 5. This is because it makes it possible for searchbots to index the web site's content., resulting in the ability to drive up the website's content in the search engine rankings. Using HTML5 for a new website can be especially effective in advertising it because HTML5 is currently causing a buzz in the industry. A quick Internet search shows you how many tech websites are reporting on websites relaunching using HTML5. For Internet users, HTML 5 has been a godsend because it helps websites stream audio and video much better than they ever could before.
SEO strategies for optimizing HTML5 code include new and improved structural tags. These are being developed as standard component of HTML. Just about every website on the Internet has a header where the website's logo is inserted. The new version of this tag can be used multiple times on one page. Header tags in HTML5 include a summary of the web page's content. These tags can now also hold links that have been optimized for SEO purposes. Other SEO strategies for optimizing HTML5 code include article tags, which are used to allow any one part of a website's article to be understand independent of the rest of the article. This allows both images that accompany an article and the text that comprises the article, to weigh more significantly with the search engines.
The section tag also helps to optimize HTML5 code by linking different sections of a website's article. This results in search engines being able to look at each piece of an article as being separate. If one piece of that article mentions a specific phrase several times, the search engine is likely to consider the information to be more authoritative. This leads to the website then ranking higher on search engines than it would have otherwise.
The aside tag defines content considered to be secondary, meaning it is not as important as other content on the website. This can include footnotes, links to sources used in a website's article and anything else that has a direct relation to the most important content on the page. SEO strategies for optimizing HTML5 code also include identifying this type of content on a particular webpage in order to distinguish it between unimportant content.
The bottom line is that those who want to use SEO strategies to their advantage can feel confident about creating or re-designing their website with HTML5. As more advances continue to make HTML5 a more mainstream coding language, it will become even more valuable to any website owner that understands the importance of effective SEO strategies. HTML5 will likely continue to change the way in which SEO is used.
