How are you including your testimonials on every page now?
If widgets, then you might consider a plugin to limit when widgets are displayed on a page.
If it’s shortcode, remove it on unneeded pages.
If it’s theme functions, you could use is_page and is_category functions to limit display.
Thank you for your response. I just added it from the “widgets” under “appearance” to the Page Sidebar. I have “short code enabled” but can’t find the actual short code. Where could I find the short code and how would I put it on the right side of certain pages on the site? Thank you.
That shortcode enabling is only for shortcodes contained within the testimonials content. Ignore that for now.
See http://www.wpmayor.com/plugin-reviews/ways-to-show-widgets-depending-on-page-or-post/ for how to limit that widget to certain pages.
