S.E.O Problems In Blogger

This usually happens with every domain name changes. Don't worry, the search engines will, over time, crawl through your blog and you'll again get your usual traffic, the one that your blog had prior to the domain name change. To help this, you can choose to submit your blog's url to some Search Engine Submission services. Alternatively, you can submit your url to google, yahoo and bing using their submission services. Google's and Bing's Webmaster Toolbox can help you do that.

Head down to the Google Webmaster and there you can find the option to notify the Google bots about the domain change and new locations..

Thanks dude,i will try my best

You may do 301 redirection from frunu(.)com to tamilkavidhai(.)com to transfer the SEO ranks achieved by previous domain name to current one.  If the previous domain name is not expired, you can set 301 redirection from domain control panel. 

Tip: Better do page to page 301 redirection
