Redirecting second TLD to one site

I have .com domain and want to redirect .net of same domain to my site.
Will that be okay for seo?
any disadvantage? which direct should i use?

any advise will be appreciated

 

Why you use a .net over a .com is beyond me, but you could use a 301 redirect.

Create a .htaccess file on the .com site with this info.

Replace the "DOMAINNAME" with your domain.

 

i want to redirect net and org to my site....

 

That's not what your first post says, but just modify that extention in the code.

 

should I add this to already existing .htaccess file..?

 

Yeah you should add it to your current .htaccess

if you're #1 position or something like that, if you redirect a PR 0 domain to your main domain, you may loose your rank possibly
