Adding Attachments to a BrightTALK Webinar: Answering FAQs

Why should you add attachments to your BrightTALK webinars and videos? This is a frequently asked question that has a simple answer: Adding attachments is a way to promote more opportunities for engaging your viewers. 

Each attachment is another touch point, another chance to deepen brand loyalty and provide valuable insights. In this article, we’ll walk you through the process of adding an attachment by answering five other FAQs. Let’s get started. 

1.  What kinds of assets can you use as attachments? 

You can use all sorts of assets as attachments: e-books, research reports, white papers, overviews, infographics – to name a handful. You can also use links as attachments, whether they be to websites, demos or other webinars. When adding links as an attachment to a webinar, the URL will need to be 255 characters or less, otherwise you will get an error.

To tap into a variety of engagement preferences, we recommend that you leverage a mix of asset types for your attachments.   

2.  What content should your attachments explore?

The attachments that you add can achieve myriad goals

Maybe you would like to provide your audience with supplemental insights about a topic your webinar explored, so you attach a research report on the subject. Perhaps your webinar references a product by your company, and you decide to attach an illuminating product overview. 

Whether it supplements information, advertises a product or accomplishes some other mission, any asset that you attach should be relevant to your webinar and position your organization as a dependable, knowledgeable resource. 

3. What types of files can you attach?

You can add attachments (or remove or re-order them) before and after live webinars. Though, when a webinar is live, or during the fifteen minutes before it begins, you cannot add, remove or re-order any attachments.

Once you’ve added an attachment, your audience will be able to find it in the Attachments tab while they watch your webinar. The BrightTALK platform can track who clicks on an attachment, offering worthwhile metrics.  

5. What if viewers do not download your attachments? 

You should not be overly concerned if your viewers do not download an attachment. Audience members may have engaged, and may prefer to engage, with your content in a different way, such as by taking screenshots during a presentation.  

Each of your viewers is unique, and so are their preferences for engaging with content. By providing attachments, you open up yet another route to engaging your audience; some of your viewers will take that route, and some won’t.
