<a href="URL of target site">anchor text</a>
If you are not familiar with URL, go to
What is URL and how you can get it.
The word "anchor tex" is a description (the title of a blog, post, anything you like) and is what will be displayed on a browser. For example, the HTML for the hyperlink to the precursor of this blog should be type as
<a href="http://bloggerfordummies.blogspot.com" target="_blank">Blogger for Dummies</a>
and in a browser, will appear as
Blogger for Dummies
UPDATE: Attributes like target="_blank" are not allowed in comments. Only a limited numbers of HTML tags are allowed in comments including <a> <b>, <i>
"Blogger for Dummies" is the anchor text and is important for the search engine uses it to figure out what is the target site (the site you are linking to) is all about. People who practice SEO (Search Engine Optimization) try to put suitable keywords (words surfers are likely to use to search for content) in the anchor text.
You may notice an extra target="_blank". This is to make clicking on the link open a new window. You can also use target="new". However, the use of target="_blank" has been deprecated. It still works, but we don't know about the future.
