HTML 5: Impact on SEO
HTML 5 is a framework that is designed to support innovation and display the current potential the web has to offer. W3C who have developed and published the framework have clarified the goal and aims:
“In this version, new features are introduced to help Web application authors, new elements are introduced based on research into prevailing authoring practices, and special attention has been given to defining clear conformance criteria for user agents in an effort to improve interoperability.”
HTML 5 also bring new elements to HTML, with new structural, inline, embedding and interactive elements. Another important introduction is the ability to include Microdata as a simple way to embed semantic markup. It must also be stated that HTML 4 is still very important and still recommended as a markup but HTML 5 allows new input controls that can be a considered addition to HTML 4.
Impact On SEO
– Microdata: This will allow you to specify multiple microdata vocabularies on a single page and from an SEO perspective it could prove to be highly beneficial. The main highlight is on structured data, giving relationships between items that can now be read in a ‘machine-readable format’ and therefore placing semantic information into code of existing web pages.
Therefore increasing website visibility to search engine result pages over pages that are lacking such content.
– Web Page Segmentation: With the introduction of new elements to help express further what appears where in the webpage allows webmaster to improve the segmentation. For example webpages can now be given, and. Allowing the number of elements to be reduced. This can also combine with the microdata above as it can allow for each tag to now be be given semantic value. As a result allows search engines to crawl the website easier and at a more advanced rate as the crawlers will be able to ‘read’ more information.
– Link Types: In HTML 5 link types can be given significantly more meaning. With the introduction of new attribute value such as “rel=licence” and “rel=author”.
As with any introductions of either algorithm changes or website markup, it will have some kind of impact on how search marketers carry out many aspects of on-page search engine optimisation (SEO). Currently from an SEO perspective HTML5 introduces many new features that help a website become more transparent and allowing crawlers to identify what and where the content is within a webpage whilst allowing a much clearer display within the search engine results pages with the use of micro data being fully optimised within the sitelinks.
