My homepage for halo-2-glitches.com has the keywords "Halo 2 Glitches" stuffed in there about as many times as possible. Look at the source code and see what I mean. All the content pictures and some of the background pictures have halo-2-glitches in their names, and they all have Halo 2 Glitches in their alt attribute. But according to the DP keyword tool, my site for those keywords is N/A and I set it to search 200 results. Does anyone have any idea why this is? EDIT: I forgot to say that this site ranks #3 for "halo glitches" but I can't find it at all for "halo 2 glitches" so that's really weird.
Looks like you've done a good job on that site. Plenty of keywords without being too spammy. Might be a good idea to mix it up a bit, e.g. "glitches in Halo 2". Nice blending of AdSense too... How long has the site been running? It can sometimes take quite a while before you appear in the search results. Google, for example, will "sandbox" new domains for a number of months. Be patient! I think you need to build some quality backlinks, from relevant directories, reciprocals and maybe LinkVault. MSN shows 45, Google and Yahoo show none. You're listed 7th on MSN, but nowhere on the other two. Also, watch out for difference between halo-2-glitches.com and www.halo-2-glitches.com - you should pick one or the other when getting links to your site. If you have a Google Sitemap setup, you can indicate your preference. Excellent tools to help you can be found at www.seochat.com and www.iwebtools.com. Cryo.
I've had the site for a few months now, with 300-600 visitors a day. I do have a Google sitemap, and I always leave the full url when linking to my page. I just spent like 2 hours validating it to XHTML transitional Hopefully that helps.
