Paresh,
I am hoping this answer isn't too late. Meta Description is what shows up in search engine results.
Usually an SEO person would add a tag - meta description tag and enter text here with the keyword mentioned in the description.
Later the Internet world stated that a meta description was not considered in SEO.
I would suggest that irrespective of what Matt Cutt and others say, we must perform basic SEO tasks. This includes adding a meta title and meta description.
If you are using wordpress, download and install the All in One SEO plugin.
