Free hosting might be one of the options for individual and personal site but even for these sites there is no guarantee as these free host providers may go out of the market any time since these host providers are not stable. One of the major drawbacks of these hosting companies that they usually put multiple ads on your site making your site looks like spammy site. Also you don’t know how long actually will be the hosting is free to you as these free host providers anytime can change their TOS and will ask you to shift to paid service. Often these free host providers place multiple external links on sites without your knowledge and just presume what would be the impact if google bots visit your site and these bots find your site facing downtime.
Also regardless the free hosting solution few providers also provide free domain name with their package, but most of people are unaware that the domain name they provide free have no control over yours as they own that domain name, also if you by any reason will try to move to another host it will be very difficult to you to get your domain name back to shift to other host. Typically the free hosting has no guarantee about the uptime and support, as these free host providers usually clearly mention in their TOS that they don’t guarantee about these two major things. if you are planning for any sort of business site - products, software, or services, or affiliate & even you are designing a blog, you should always go for paid hosting. On other hand the Paid providers will almost always give you a space and bandwidth, 24×7 support and superb uptime unlike some free hosts. It’s easy to fall in to the trap of choosing a free host those attract with the ads like “free host” ” free domain” “free website” in the belief that such providers offers free hosting, free domain, unlimited space etc than a paid alternative that obviously not true as any company that offers anything free has to make this up somewhere else in due course or it cost you in different ways and that will be heavily even. So best to go for paid hosting to provide your customers a professional service without putting them into problem.
