Give it time. It can take up to an hour for your SourceKnowledge Pixel to activate.
Make sure your pixel is placed directly before the </body> tag. This ensures that the script loads correctly and has minimal effect on rendering your page content.
Check your formatting. Altering your SourceKnowledge Pixel, including changing formatting affects the script’s ability to fire. Your SourceKnowledge Pixel should be placed on all pages of your site exactly as it was copied.
