When you visit a website on an iPhone or iPad, data exchanges are saved on the device. Cakes and other cached data eventually begin to take up significant space, so you may want to clean them. Like this.
Periodically clearing data as iOS stores can be a good idea for a number of reasons. In addition to the fact that these sites collectively store a lot of data on your devices, this data can be used to track your visits as well. Websites save cookies to your devices in order to tell you when you visit again, and while it may be beneficial to stay logged in and save settings, not everyone likes it.
If you want to make sure websites can "keep tabs on you, you might also want to remove the information they save to your device. If you're small in space, you might just want to clear everything.
