When writing a post, if you use a term that might not be clear to some readers, make it a link to the appropriate Wikipedia entry.
For example, in a post intended for beginners, Your first blog, I used the term WYSIWYG to describe a feature of someÂ editors. This term can be linked, as I have done, to the Wikipedia page http://en.wikipedia.org/wiki/Wysiwyg where it is explained as “What You See Is What You Get”.
As an added bonus, this allows you to add a “title” tag to the link so that when the user hovers their mouse over the highlighted term they see your user friendly explanation for the term, even if they don’t take the link, as shown here:
Of course, if you have another post about that term available, then link to that instead of Wikipedia. As a second bonus, the outgoing links and the keywords in the links may also help your search engine rankings.
