Owning different websites is a must in this industry. On this list would be your WordPress blogs, which you will find is needed with each different niche that you pursue. Having a reliable yet inexpensive hosting service is a must. My personal favorite is Bluehost yet a lot of people seem to like Hostgator. A few other services that I have heard are really good are Monster Host, Just Host, IPage and Green Geeks.
You also need to make sure that your chosen web hosting provider has an easy to use control panel. Some control panels can turn your hosting account management to a nightmare. cPanel and Parallels Plesk are both great control panels to consider. Moreover, be certain that your provider provides a 24/7 support.
You will no longer need to think about things such as bandwidth, disk space, domain names, various scripts etc on your own. Web hosting review sites will help you through the whole process. All you have to do is look at a comparison chart and select your future web hosting provider.
Many web hosting providers offer ecommerce packages to help you open and manage an online store. They offer searchable catalogs, shopping carts and credit card services.
Should you ever find yourself needing web hosting there will be no shortage of companies willing to take your money. To the average person, plans for less then $5 a month with "unlimited" bandwidth and storage seem like the best option. Unfortunately, this is just a creative ploy to get you to hand over your money. It's all in the terms of service and contracts that you agree to when you make a purchase. Should you decide to ever read those, you will find what unlimited really means.
Do not waste your money on features you do not really need. Some web hosting services charge you an additional fee to register your domain name or for a certain number of email addresses containing your domain name. You can save money by purchasing this service from another site; in fact, it would be a better option since you might lose your domain name if you decide to cancel your plan. You can read more also save money by not purchasing additional features such as a web building tool and using a free plugin instead. Pay attention to the plugins and languages supported by your server; make sure your server supports everything you plan on using to develop your site.
