tad too dark or my likes, your logo is also too close to the alienware one.
the google adverts also make it look like it's hosted on a free host site... I know that these things get money in; but I'd be surprised if it was much or that people will apreciate having such crap in their face.
I know that adverts on a site put me off to a point where I'll just stop using it most of the time. It often really puts me off here, cause they're sodding everywhere... and for a company that is supposidly successful just not really any excuse imo
also it is a little too plain as far as a website goes, again screams "cheap" from the get go; while the nice package graphics distract from that a bit, you're back in when you start reading again.
your copyright, doesn't really cover you if someone steals your stuff; as well as a TOS and Privacy Policy are really needed again to legally protect yourself. always think "down-the-line".
no-fixed width text is also a big no-no. means it won't appear the same on all resolutions; always try to keep to a 720x350 viewspace mentality... the height isn't so much of an issue but width is.
make sure it supports the lowest people are likely to use (Windows XP and Vista this is 800x600 minus menus and boarders)
embed videos, there are plenty of free: Flash, Silverlight, Soap.. things for embedding videos without degridating quality.
In-fact Silverlight actually compresses extremely well, is highly adaptable and microsoft offers free hosting space meaning it doesn't use your own bandwidth.
additional menus try to keep as sub-menus without replacing the main one; as it'll confuse navigation.
try to keep features of something as bullet-points, perhaps linked to a hover-over swapper to show what each feature does.
screenshot systems are also plentiful (some very good silverlight, flash and javascript ones) that'll allow you to put a band someone an expand without opening a new page. make use of these as people enjoy being able to view something quickly.
while you want to keep people on your site longer as it means they're more likely to purchase something; you have to do it without forcing it upon them. make it something that peaks their interest to keep checking things out.
huge images at the top of pages without any text for example =!good
pretty hooks someone, but they need to also quickly get into what something is about.
provide some news as well (easiest way is implimenting a blog system like wordpress) so people can keep up to date, especially good if the blog is tied to an RSS Feed.
