StumbleUpon helps people discover the very best websites that match their personal interests. We are unique because our sponsored content is displayed in the very same way our users Stumble on normal websites. Therefore, it’s important that your content (your ad) is as relevant and high-quality as the other websites on StumbleUpon. Our millions of members are looking to discover new and interesting information, and will give you valuable feedback (thumbs up or thumbs down ratings and user comments) if you provide them with an entertaining or informative experience.
For best results, StumbleUpon provides the following guidelines. Please note that all ads placed on StumbleUpon must adhere to these guidelines, and StumbleUpon reserves the right to reject any content that we deem contrary to our ad philosophy. These guidelines are subject to change at any time.
Please note, our Ad and Content Operations team manually reviews all sponsored content submitted to StumbleUpon. The review process usually takes one (1) business day and we have very limited coverage during weekends and observed U.S. holidays.
