What affects website bandwidth
Page weight
Large images, video, JavaScript bundles, and web fonts increase data transferred per page.
CDN and browser caching
Effective caching can reduce origin bandwidth because repeat assets are served from a cache.
Traffic outside analytics
Bots, API calls, downloads, backups, and hotlinked files may use bandwidth beyond normal page views.
How do I calculate website bandwidth?
Multiply monthly visitors by pages per visitor and average page size. The result is converted from MB to GB.
Is 300 GB of bandwidth enough?
It is enough for the example of 50,000 visitors viewing three 2 MB pages each. Leave headroom for growth, bots, downloads, and traffic spikes.
Does a CDN reduce bandwidth?
A CDN can reduce bandwidth served by your origin host, although total visitor transfer remains similar.
What should average page size include?
Include HTML, CSS, JavaScript, images, fonts, and other resources normally downloaded for one page view.
