Meta data is information that is placed within the HTML code of a Web page. It is not
intended to be viewed by visitors — it is intended to be seen only by search engine
spiders and browser software. Meta data is one of the factors search engine spiders
use to rank websites. They look at the meta keywords tag which essentially tells
spiders what the Web page is about, and they look at the meta description tag which
tells spiders how the page should be described when listed by search engines. It is
important to understand that not all search engines consider meta data when reviewing
websites, but nevertheless, it’s important to include tags on all pages of your website
for the search engines that do. Moreover, a well written meta description can increase
the click-through rate of your listing from search engine results.
