Bluehost (established in 1996) is the most reliable beginner-friendly web hosting out there. The cheapest plan starts from just $2.75/mo (if you pay for 36-month in advance), renewals start at $7.99/mo. With the basic plan, you can host 1 website. The plan includes a free domain for 1 year, 50GB SSD storage, unmetered bandwidth, free SSL and 24/7 live chat support.
It shouldn't come as any surprise that, like other web host providers, A2 Hosting's unlimited plans aren't actually unlimited. It expect you to use its service like "similarly situated customers." This is like being on a highway. If everyone is going a few miles above the speed limit, you're probably okay, but if you're barreling down the fast lane past everyone else, you're probably going to be asked to slow down.
