> don't know how to add more pages with out it looking dumb
Whatever your site's main topic is, you can always add more content. Each additional page may not be the content that every user is looking for, but each additional page is something that someone will look for, eventually.
The problem, as I see it, has three parts:
1: Figuring out the content you should add to the site.
2: Writing the content.
3: Figuring out where to put it.
1 - Figuring Out the Content
You can do this in tons of different ways. When I was recently searching to expand content on one of my sites, these are the steps I took.
First, sit down with your topic and a blank sheet of paper. Try as hard as you can to FORGET everything you've got on your site right now. Next, clear your mind of everything except your site topic. Now - brainstorm. Write down everything that comes to your mind, no matter how closely or loosely associated with your topic each idea is. If you run out of ideas, start asking yourself questions. "What would my mother want to know about X? What would Harrison Ford want to know about X? If I could meet the maker of X, what would he say about it?"
Once you've exhausted your brain, take a break. Put away the paper. Go away from the topic for awhile.
Next: search the web. What are other, related sites saying about your topic? What are seemingly unrelated sites saying about your topic? (Ah-ha! They're actually related, which gives you some extra ideas.)
Next: ask your friends/coworkers/busdrivers. Either be direct ("I really need to add more content to my site about X ... do you have any ideas?") or be indirect ("Barkeep, give me a pint of Guinness. Oh, and say, did you hear the latest about X? What did you think about it?"). But ask people, and give them a chance to add fifty ideas to the ones you've already come up with.
Finally: pull together all of your sources. Yes, you'll have about a thousand dumb ideas that won't generate a page of junk. But you'll have several gems to work with, places you can add totally new content, places you can expand existing content, and places you can work in tangential content.
P.S. Keep that piece of paper that you've used to make your lists. It'll come in handy later.
2 - Writing the Content
Can't help ya there. Either do it yourself or hire it out.
If you want or need to do it yourself, try not to think of it as an overwhelming task. A few years ago I participated in National Novel Writing Month ... I churned out a 50,000 word novel in 30 days. Was it terrible? Mostly. Was it difficult? At first. But then I realized I only needed to write 1667 words a day. That's nothing. I've already got 475 words in this post!
Stephen King has said he wakes up early and writes at least ten pages every day. They may be awful pages that don't all get used in his novels ... but he faithfully writes 10 pages a day.
If you sit down and write as little as 250 words a day - 250 words! - you'll have generated tons of content for your site in no time.
3 - Where to Put It
Oh, sure. Some of the stuff you write will go right into the hopper. But believe it or not, most of it can go onto your site and will generate traffic!
Remember that piece of paper you used to generate all of the silly lists of content ideas? Get it out and take a look at it. It's likely that there are lots of groupings of ideas on the list.
Sample list - Widgets. Red widgets. Small red widgets. Famous people who own small red widgets. Famous peoples' collection of widgets that include red widgets but also include blue and green ones. Red widgets for midgets. Widgets and the women who love them. Widget school. Accesories for widgets. Accessories for red widgets that work with blue widgets. Accessories for red widgets that don't work with blue widgets.
you'll see natural groupings and linkages emerge simply from the way your list was written (or scribbled). Do you already have a section on red widgets? Add the 'small red widgets' and 'accesories' articles there. Already have a FAQ on widgets? Link to a fabulous article on widget school from the FAQ.
Feeling stuck? Add a "Miscellaneous Widget Information" section to your site and just junk all of the extra articles in there. Link strategically to and from those articles. They don't have to fit perfectly - and they don't have to be displayed prominently. But they can still work for you.
Content can be a bear. But I've found that the hardest thing about dealing with content is getting up the momentum to do so. Just starting the process - either by doing some of the things in this post or doing it your own way - is going to get your site cookin'. It doesn't matter whether you use grace or brute force to get the content onto your site - because you'll benefit from the content either way.
