Seven years ago, when my first Who Pooped in the Park? book was hot off the presses, I cut one up, scanned it, and turned it into a PowerPoint presentation.  I have used that slide show many times, and I learn something new every time I give a talk. That, actually, is one of the things I like most about public speaking: if I do it right, I learn as much as my audience does.

Among the things I have learned are:

• Carry props. It keeps the talk more interesting if you can show people something tangible, not just pictures.
• Move.  Don’t just park yourself safely behind a lectern. This may be controversial advice, because a lot of speaking coaches will tell you not to wander all over the stage when giving a talk, but my primary audience is children and they bore easily. I move around, point at the slides, hold up props, walk over to audience members and hand them things to pass around. I’ve even been known to demonstrate different gaits.
• Engage the audience.  Ask them questions. I like to ask where people are from at the beginning and make references to their home states or countries later during the talk. Address people directly.
• If you expect to sell books after the talk, mention the book. Say something about how and why you wrote it. Put a picture of the cover on one (or more) of your slides. And mention that you’ll be selling and signing books after the talk.
• Make sure you have contact information on one of your slides in addition to having bookmarks or business cards available. That makes it easier for people to send you pictures they took, or invitations to other events. Instead of an email address, consider using your website, Facebook page, Twitter feed, and other social media contact methods. You’ll get less spam that way, and you may pick up followers on those sites.

And, to bring this back to the main subject for the day, customize your slide show. I just gave a talk at the National Bighorn Sheep Center in Dubois, Wyoming a few days ago, and we did a book signing afterward. Here’s what I did to customize the PowerPoint presentation:

First, the opening slide. The top half of the slide has the book banner on it. I went to the Sheep Center’s website and grabbed a picture with their logo, added that to the bottom of the slide, and overlaid the date. I set up the projector in advance and left that slide up on the screen as an introduction until the talk started. That way, attendees wouldn’t just think, “oh, this is some generic presentation,” they’d know it was in some way connected to here.

Next, since the Center is all about bighorns, I figured I should insert a picture of a bighorn sheep. When I am doing slide shows, my first preference is always to use a picture I took myself. If I don’t have an appropriate shot, my next stop is either a stock photo house or Wikipedia, so I know I am using the picture legally.

I have an account with a stock photo company from when I published a newspaper. Generally, I am not going to pay $10 or $20 for a picture I am using one time in a slide show, unless it’s absolutely perfect. This stock photo shop, however (Dreamstime) has a free photo section which sometimes has what I need.

Wikipedia (or, more accurately, Wikimedia Commons) has a wealth of photographs that you can use in slide shows without royalties — just check the license.

Since I didn’t have a good bighorn sheep picture of my own, and there weren’t any cheap (or free) at the stock photo house, I picked one up from Wikipedia, overlaid some scat and track photos, and it made a perfect slide.

The local bookstore in Dubois set up and promoted the talk, so I added a “thank you” slide at the end. It’s typically easy to get logos from a store’s website or Facebook page. After they put a bunch of time and effort promoting the talk, it means a lot when you go to the effort of making a slide to thank them.

I am not a “read from my notes” kind of guy. I think it sounds awkward and stilted, and when you are reading from notes you aren’t looking at your audience. If I know my subject matter — and I had better! — then all I need is an outline, to make sure I don’t forget anything important.

That makes it easy to tailor the talk to the audience, since I am speaking extemporaneously anyway. Spending an hour or so customizing the slides makes it look like you have really put forth an effort, and that’s the kind of little thing that gets you invited back.
