Thanks for sharing these details and I agree that banners are a source to get the attention of potential customers but I don't believe printed banners are game changers nowadays. In my opinion, these are GIFs or animated banners that are changing business games recently.
Even it is not only seamless to create animated banners by using online tools like BannerBoo https://bannerboo.com/create/animated-gif-banner/ but it is also inexpensive compared to printed banners. For printed banners, you don't only have to pay the printing fee but advertising charges also apply in the majority of cases. On the other hand, it only takes a few clicks to build and share your animated banner online. By the way, social media or online marketing charges are also less than conventional marketing means.
So, which one you should prefer to choose?
