how can i add my site free to search engines?please refer some sites?

Answer 1

It is not necessary to submit to any search engines because they have bots which crawl the web looking for new sites (pages). It is better that they find you this way.

Also using automated software to submit to search engines or directories is a silly mistake that a number of people make.
