One thing we learned in reviewing the services listed here (and many more) is that even though the packages are very similar, they are not identical. Some are more security-focused than others, offering anti-spam and anti-malware tools. Others offer a variety of email marketing tools. While most of the hosts we've reviewed have built-in e-commerce, you may want to consider using a more-robust third-party online shopping cart application like Shopify instead.
I wanted to point out that you do not mention critical issues. One is that some of the Top 5 Hosting Services do not offer an e-mail account. Others charge $14.00 a year to transfer your a Domain Name and host it with them or else the domain owner does not get the hosting for free. The list of unpleasant conditions that render those top 5 Hosting Services substantially less appetizing than you painted the picture, and that list goes on and on.
Used 000webhost back in ye olde days. Back then it was the only legit free host, and others were data scams, or so it seemed anyway, because the computer antivirus (old Avast) could go into a meltdown once you visited their websites. Looks like the times have changed – but I’d keep tenacious about my personal data around most of these companies. If they don’t make money with hosting, it’s anyone’s guess how they make that money..:)
Website hosting is typically measured in the amount of disk space you're allotted on the server and the amount of data transfer or "bandwidth" you need for accessing the server. For example, if you have a lot of customer interaction at your website, such as files to download, you will access the server frequently and you'll need more Web hosting transfer space than someone who simply puts readable text on their website. The more "items" or "content" you have on your site (i.e., photos, maps, PDF files, etc.), the more disk space you'll need for website hosting.
