Using meta data to manage the site description in Search Engine Results.
Description Meta Tag
Google, for example, advises using a good Description Meta Tag. The Description tag is typically auto-populated from the page description.
DMOZ
In addition to adding description Meta Tags, ensure that a search engine isn't using a description from DMOZ (Open Directory Project: http://www.dmoz.org).
Google can be directed to not use DMOZ as source by adding a ROBOTS meta tag to your pages. When populating the meta data use the following value:
noodp
This should help prevent search engines from using an inaccurate description from DMOZ.
