Did you know that you don’t just have to scour the web for Keynote based websites. There are TWO great online markets that sell Keynote themes. Graphic River and Creative Market
(disclaimer, these are both affiliate links)
A part of the Envato family of sites, Graphic River is filled with amazing graphic resources and one of the categories is Presentations. They offer both PPT and Keynote, and at pretty good prices too. (make sure you visit the other great Envato sites too!)
You can visit Graphic River here:
(yes, this is an affiliate link. I get credit if you purchase after clicking the link. If you do NOT want to use this link, simply type in graphicriver.net into your browser).
Similar to Envato, it’s filled with amazing (and inexpensive) graphics, templates, fonts and of course, Keynote Themes. One great benefit to sites like this is that while you can grab a Keynote theme or two from here, you can also grab items to help you with your presentations. Lots of vector art (which should import into Keynote as a PDF), fonts, and PSD effects are available.
You can visit Creative Market here:
(again, this is an affiliate link. If you don’t want to use the link, just type in creativemarket.com in your browser to visit it directly).
