Search Engines -- Submitting a Second Domain Name?

I just registered a new domain that points to my current website, in order to help visitors find my site easier. Is it considered spam to submit your new domain to search engines, even though it goes to to your website that is already listed on the search engine? If it is, how are you supposed to get your new domain heard around the web community?

no, is not spam. If you don't already use it, I suggest to add a sitemap and submit to major search engine. For google:

you can do this also for yahoo and msn.

So should I send the sitemap URL, the homepage url, or both?

no, you build and submit a sitemap file, google/yahoo/msn accept xml format.

sitemap info, and details if you want to build manualy or to know how must be:

google info about create and submit:

webmaster tools for google:

same things, site explorer, for yahoo:
https://siteexplorer.search.yahoo.com/

msn work almost exactly like google and yahoo

No it isn't, just make sure to use a permanent, not temporary redirect.

And to be heard around the community, you do that by link building. In other words, your site's content must be so good that some of your visitors take time to post links to your website from other domains.

The second domain won't benefit your search engine ranks unless you promote it individually - at which point, you may as well have promoted the original site anyway.

By all means ensure the domain redirects to your main one in order to capture type in traffic on that domain, but don't see this as an SEO opportunity.

Well my thinking is the new domain name I purchased will be easier to find than my current one. Rather than it having to do with my site's name like my first domain, its name is more focused around the keywords that a visitor would be more likely to search on a search engine.

Keywords in domain names have a limited impact on rankings. Because the new site is redirecting to the original site you can't optimise it's content (because it doesn't have any). As such you are relying on the domain name and any links to get a high ranking, which users will click on and be redirected to the original site.

I guarantee if you get the same links to point to the original site, and actually optimise the content of the original site, you will have more success.

its name is more focused around the keywords that a visitor would be more likely to search on a search engine

1) The name of your site is going to be a major keyword, so as Pennimus suggested, focusing on your original site is best.
2) Don't fret though, your new domain name will benefit your SEO if you both a) use a permanent redirect (301, as stan suggested), and b) gear your content to match your new domain name.
