Carl, I took a look at your site and have some ideas what might be going on. First the good news. Both
Yahoo and
MSN seem to have begin indexing the site. One immediate thing I noticed is that you have cannonical url issues. What that basically means is that freeplayerzone.com and
www.freeplayerzone.com are seen as different urls. You want them to be seen as one. It doesn't matter which though the standard us usually to point the non www to the www domain. I wrote an article on
301 redirects which I think will explain the issue and also has links to a few sources that show you how to set them up based on the type of server you have.
Now for the bad news with Google. I wasn't able to find your site anywhere in Google like you thought. I think the issue is caused by a couple of things. First your site is about games and the links to most of those games are javasript links. Google can be tripped up by javascript and probably isn't getting to the pages with the games embedded in them. I'm actually a little surprised Yahoo and MSN do seem to have gotten past the javascript.
When you take out the games which is how Google likely sees your site what's left is essentially links to other sites, many if not most of which are unrelated to your site. As far as Google is concerned there's not really a reason to index the site. All they likely see the site as is a list of links to other sites already in the index. They probably don't see much value in your site for people who use Google.
A few months ago Google went through what's known as the Big Daddy update. The update was about how they search and index websites. I think the changes apply to your site and are possibly the reason Google isn't indexing it. Matt Cutts wrote a post on is blog called
Indexing Timeline about the update which you might want to read.
My suggestions would be to fix the links on the site so they don't include the javascript. I'd also add more content to the site. Maybe articles about the different games or anything else you can think to say about them. Many of the links on your site look like advertising. You might want to cut back on a lot of them or use rel="nofollow" on the links if the ads are more for the direct link from your site than any benefit from Google. Given the site isn't indexed I doubt there's any benefit through Google anyway.
You should also try to get more links pointing to your site from trusted sites and sites related to yours. The more trusted and related backlinks you get the less will be the effect of the current unrelated ads on your site now. I didn't check the sites you link to, but I would guess they're not seen as trusted sites in Google's eyes. Just a hunch on my part.
One quick way to get a few links is to add one in your forum signature here and on any other forums where you post. They probably won't do a lot to outweigh the ad links you have, but they will get spidered by Google and it's a sure way to know Google will at least be aware of your site.
Better would be to post on forums related to online games. I'm sure there are plenty.
I hope that helps. I don't know that it's what you wanted to hear and I may not be 100% right, but I have a hunch the issues I've described are what's causing the problem. Others may be able to look and offer more possible causes and suggestions.
