I have found a few good dot com domain names containing keywords, phrases with good Google counts. I already have a good events website established but I am always looking to increase traffic volume. This is what I am trying to figure out; for example say my existing domain is laeventsnow.com my new domain names are: la-events.com eventsinla.com Will it help or hurt to use these new domain names and redirect them to my current site? Any thoughts on this?
If you do a 301 redirect, then having these additional domain names won't do you any good at all. If you so a 302 redirect or put up a copy of your existing site, Google will see it as duplicate content and ignore the two new sites. If you put new content on these two new pages and put a link to your existing page, that could help. Of course for these new sites to have much authority to pass along, you'll need to spend time SEOing them.
Why not just develop them, rank them and get a bigger share on the SERPs then place banners for your main site in the new ones?
Right! The best way is to put some content on this websites and use them as Door Way Traffic Sending pages
I agree that a network of 1-way linking sites is a good idea. If going that way, be sure to host them on different servers/IP's, and and keep the content unique. Another thought: temporarily point both names to the same (current content) and try a little Adwords PPC on both. See if Google gives on a higher quality score. If so, you might concentrate on that name -- either for PPC or organic SEO. I say this because I once purchased a domain name to promote a product (call it "keyword1 keyword2"). So I bought domain name "keyword1-keyword2.com". I thought "what a perfect domain for promoting my two target keywords". But Adwords consistently gave my landing pages on that domain a low quality score. So eventually I bought another domain "keyword1-keyword2-keyword3.com" and Adwords immediately gave it a high quality score, and lowered by cost-per-click. What I'm saying is: it might be a good idea to use the Adwords interface to "test" both the domain names a bit before focusing your efforts on one or the other.
