Animations can absolutely make a website look better when they are done well. They can enhance the visual experience, attract attention, and make the site feel more dynamic and engaging. In that sense, animations are often a nice feature to have.
However, they are not a necessity. The main goal of a website is not to show off animations. The main goal is to help convert visitors into paying customers. If animations support that goal, great. But if they interfere with speed, reliability, or clarity, then they are doing more harm than good.
That is where the tradeoff comes in. Poorly implemented animations can create delays in loading time. If those delays become significant, they can hurt the user experience and push visitors away. So animations should never be added just for decoration without considering their effect on performance.
The best way to think about it is this: animations are helpful if they improve attention and presentation without getting in the way of speed. They are valuable only when they serve the function of the website instead of distracting from it.
The answer presents animations as helpful but secondary. They can make a website feel more polished and visually engaging, but they should never come at the expense of speed or functionality. The speaker repeatedly returns to the idea that the website’s main purpose is conversion, not simply visual flair. In that context, animations are acceptable when they support the user experience and harmful when they slow down the site or interfere with usability. The core takeaway is that animations should be approached with discipline: they are “nice to have,” not essential, and they should only be used when they align with the larger business goal of making the website more effective rather than merely more decorative.
