Using google custom search in my website will improve my site

will using google's custom search in my website will improve my site. Because When I putting it in my site I can increase traffic by search engine referral.

 

I do not think so.

 

Google search result are integrated into the site design , it gives a broder idea of search with out confusion. It increases user experience and site.

 

it's not going to increase your traffic if thats what your asking

 

No its not going help you in any way.... Its just an extra feature for the readers...
