Keyword emphasis is a means of highlighting text within a page. Keyword emphasis can be utilised in a number of different ways for a number of different reasons. Typically, website emphasis was a part of the initial HTML coding standards. Even to this day, keyword emphasis and content emphasis remain incredibly popular, moreso for the end user rather than just search engines.
When emphasising a keyword, it becomes a highlighted object within the page designed to stand out to the end user. Keywords and content can be highlighted to make sure it is seen as a prominent part of the page, wether it is content related or image related.
Using content and keyword emphasis, you can highlight single keywords or multiple words in a sentence. More often than not this system is over used or not utilised properly. When highlighting information, it should be so that the end user can understand the information to be important. Search engines can detect when this tag is overused, or when it is used out of content, perhaps to highlight information that has no relevance to the page, i.e. CLICK HERE or MORE INFORMATION.
Within content, highlighted keywords not only stand out, but it also shows the end user that the highlighted keyword is a point to remember or to understand further. References are also highlighted in content emphasis tags.
Keyword emphasis is a tag that can have a mixed approach, typically it is designed for highlighting content and not for SEO purposes, it is designed for the highlighting of selective content, but when used effectively can have beneficial effects towards a websites SEO status.
Keyword emphasis is typically integrated using a BOLD tag within HTML. This is represented with a <B> tag and closed with a </B> tag. What ever content is placed between the open and closed bold tag will be highlighted on the page as follows:
No Bold: The World is full of Surprises
Bold: The World is full of Surprises
Another tag that is frequently used is a strong tag which is opened and closed by <STRONG> & </STRONG>. This has the same visual effects as a bold tag, but is a different representation within HTML. The influence is the same as a bold tag.
