Bandwidth translates to the amount of traffic and number of page views your website can handle every single month. It’s becoming common practice to offer unlimited bandwidth. However, there’s a chance this could get throttled down, or your site could go offline if you’re experiencing a massive traffic surge—such as during a holiday sale or if one of your blog posts just went viral.
If you’re on a shared hosting plan that offers unlimited bandwidth, keep in mind that unlimited might not really mean unlimited. Generally speaking, a site on a basic shared hosting plan can handle up to 30,000 visitors per month before you’ll notice that your loading speeds start to increase and your site performance starts to drop. However, if you’re at that level you can probably afford to upgrade to a better hosting package.
The other consideration is storage. The limits for storage vary widely across hosting companies and platforms. However, unless you’re storing videos, collecting and storing user data, or a ton of media content, you can probably get away with using minimum levels of storage.
