Differencies Domain .Net and .Com

I am familiar working to optimize domain .com, not .net. Anyone can share: “how to optimize domain .net?” I have one domain .net and it’s difficult to do it for optimization. Thanks a lot.

[ot]I have moved this from the .NET section to the Internet Marketing section – .NET is a programming language, not an area to talk about .net domains[/ot]
In terms of SEO, there is absolutely no difference between a .net domain, a .com domain or any other TLD (with the exception of country-specific domains). The same techniques that will rank a .com website will work exactly as well for a .net website.
