I like the site, torstan! Nice and simple and to the point. I would give you some rep for that alone but I need to spread it around a bit more before I can.
A few technical (mostly SEO) hints I would recommend are:
* include an 'alt' in your image tags. For example,
The alt tag will help people who have images turned off (for one reason or another) or for some reason the image doesn't load properly (the alt text will get shown instead). Course a SEO (Search Engine Optimization) trick is to put one of your keywords in the alt area since Search Engines pick up on this.
<img src="Gallery/Recent/DreestonThumb130.jpg" alt="Dreeston Image Link" />
* include a 'title' in the link tags. For example,
In some browsers, the title text will pop up when you mouse over the link. It is also a good SEO trick since Search Engine pick up on the title tags.
<a href="Gallery/Regional/dreeston.html" title="Dreeston Gallery">
* another SEO tip is meta-tags. There is some discussion among the SEO community if meta-tags are still relevant but I personally think they don't hurt and may end up helping out in the long run. Meta tags I would recommend are:
The author tag is self evident. The robots tag and the revisit-after tag are instructions that search engine robots are to follow when visiting your site (for cataloging purposes). You should think about having a robots.txt file on your site as well since search engines will be looking for it. There is a lot more info about the robots meta-tags and text files here.
<meta name="author" content="Jonathan Roberts" />
<meta name="robots" content="all" />
<meta name="revisit-after" content="7 days" />
<meta name="title" content="Fantastic Maps: The Cartography of Jonathan Roberts" />
<meta name="description" content="The Cartography of Jonathan Roberts." />
<meta name="keywords" content="fantasy cartography, role playing game maps, rpg maps, D&D maps" />
The title and description tags are important because this info is what search engines often pick up on when they display your site in search listings. A SEO trick is to put some of your keywords into your title (which you did by adding cartography to your title). Speaking of keywords, they are important as well. These are the phrases people use when searching so you want to have the right terms listed. keywords are losing their strength in search engine results but they aren't obsolete yet so I recommend using them. Getting the right keywords is an art. Specific keywords (ie rpg maps, fantasy maps, d&d maps, etc) are more likely to bring people to your site who are looking for those specific terms over general keywords (ie maps, cartography, rpg, etc). I recommend having a balance of both and no more than 25 such keywords. I could write pages about keywords and their use.
Finally I also recommend having a HTML based sitemap that collects are your links in one location. This can be handy for the user and search engines love it. Speaking of search engines, I also recommend having a sitemap.xml file on your site as well. Like the robots.txt file, search engines pick up on this file and it helps with your listing in search engines. More info about sitemap.xml files can be found here.
The reason I mention all of this stuff is because building a site isn't enough these days. The trick now is to drive traffic to it. The above tips will give your site an edge over similar sites that aren't using these tips. Course things like links to your site is where you build your search engine love but that is a whole different tutorial.
Best of luck on your site and commissions!
