1.I want sell some product to usa people and don't know - invest and buy .us domains or cheap .info ? 2.What is the best seo friendly cms ? or maybe standard site is 100x better ?
1. If you can register for a .us domain, then go for it 2. It would depend on your application. What are the features that you need to have for your site?
You can give Joomla a try. You can make it Search engine friendly completely with about 4-5 Addons installed. Cant remember all of them at the moment. 1 for ".html" suffix 1 for sitemap 1 to show related items 1 to get related articles and some more if you like it. Give me a rep if this is useful.
I've used joomla and plone, both work good for SEO friendly URLs. Plone is much more powerful but more difficult to configurate and use.
ok.last question - example - i will be have site about computers. If domain cheap-computers.us will be better for seo optimization that my-site.us ? will be higher in google results ?
I think both are good. But you'd better choose cheap-computers.us first. You can use a good unique brand later.
I'm really impressed with this little known content management system.. it does SEO friendly URL's and even lets you customize the <title> and meta tags for every piece of content you add in.. You can make the CMS do anything.. cater it to the needs of your website. I use it on all my projects: http://english.cutenews.ru As far as .html being the best extension.. I don't think that's so true anymore.. .php and .asp have become pretty common and respected as well.
I know you've gotten your answers but I figured I would add another vote that joomla is pretty good. It's not the most powerful (or secure even, being php based) but it is the easiest to figure out. Because of that it can end up being pretty customizable too.
