I'm not trying to be traditional here. We make signs, and upsell to as large as possible. Why would I use a 18x24 corex for my header when a billboard costs the same?
I use Handel Sans for "Signs & Graphics" ALL CAPS because nobody else does and I like it. I own the Adobe Font-Folio as well as 3,000 other fonts and chose this one with nobody breathing down my neck. Haters gotta Hate...
I used Arial on the website, with no CSS because it works very well, and 9/10 people cannot differentiate it from the almighty Helvetica, and 8/10 people don't even know what a font is. So as far as SEO goes, keep the font-snobbery away please. My target market is not other Graphic Designers, it's Joe Schmoes White Van New Business.
As far as the links page goes, you might want to take a look into the SEO benefits of "back-linking". All those stupid links improve the credibility of your site, which is more heavily weighted than meta tags for page ranking. Also note the descriptive "alt" tags on every single image. Much more important than the font they are displayed in.
And as far as page margins go, I would love to glean some of the knowledge you speak of. In the era of smartphones, tablets, and everything else; I can either "pinch-zoom" or "CTRL + Scroll Wheel" and re-define any Page Margin to my screen in seconds. Go ahead and waste your time on that "antiquated" design element.
If you are still reading, darn right it took up your whole screen. The site is a static 1400px wide. Any HD screen will have 1920px to work with. If 1400px took up your whole 27" screen, you probably have it set to HD Zoom or some other BS because I actually set my screen margins for HD devices that are running normally, and still have 260px of negative space per side.
Thanks for the TYPO comment however, that was helpful. Everybody else, Stay Lame. (haha, j/k, thanks).
