I see you've got some good advice here already, but I thought I needed to chime in.
The keywords you stated before of "templates" and "tutorials" have got to change. Tutorials won't get you anywhere. What types of tutorials do you have? You need pages that are very specific to the type of tutorial you have. Are these building website tutorials or framing a house tutorials? I'd assume it's not framing a house, but just the keyword of "tutorials" doesn't tell me. Enunciate exactly what you've got and that'll help the engines know what they should make your pages show up for.
This is a page you should keep an eye on. The beginning of all of your titles listed is the same and rather useless. Best case, get rid of the site name in the title. Worst case (if you just can't bring yourself to do that), move it to the end. Those first characters are valuable space for
SEO.
I also see several documents titled "Printer Friendly Version". I'm assuming that's some article you have on your site with a printer version. Since you probably have the same document in a non-printer friendly version as well, this would be duplicate content. Best idea is to use a robots noindex, follow meta tag on those pages to prevent them from creating duplicate content or use your robots.txt file to prohibit print.php from being accessed. Either way, you don't want those duplicates in the indexes.
I also see some documents indexed as wise-designs.com and others as
www.wise-designs.com - this is also a source of duplicate content. Use a 301 redirect using mod_rewrite since you're on an Apache server on a *nix variation. Just make sure you get your rewritecondition correct so that you don't get an endless loop of redirects.
When you get done with your titles, there's always more to do. The metas (keywords and description) won't make huge differences in rankings, but killing some of those optional ones can certainly help in MSN and Yahoo at the moment, especially the revisit-after tag. I've seen more than a few sites have issues that are resolved after removing that tag.
Happy coding,
Brian.
