WORDPRESS WIDGET EXAMPLE
WORDPRESS PLUGIN EXAMPLE
If you don’t feel comfortable messing with the widgets you can also install a plugin called Raw HTML Snippets. This plugin will NOT taint your content or the output of other shortcodes. You simply install it, create a new snippet, call it omgcode, then paste your custom code inside that snippet, and then grab your new custom [SHORTCODE] to paste anywhere on your site where you want the OM Guarantee certification to appear.
