In the source of your website the following tag can be found to clarify abbreviations for the spiders of search engines:

<acronym title=”Search Engine Optimization”>SEO</acronym>
<abbr title=”United States of America”>USA</abbr>
<abbr title=”Bank of America”>BOA</abbr>

An acronym is a abbreviation pronounced as a word. Sometimes it is required that every letter means a separate word, like an initial word. An abbreviation is a word like IBM, USA or YMCA where you have to pronounce all the letters separately.
