There was a time when free web hosting services were extremely popular. But, over time, their level of popularity decreased, due to an absence of support, low level of reliability, and higher downtimes.
As the profitability of online businesses grew higher and higher, everybody started using paid shared web hosting services, which involved annual subscriptions, but ensured that you could call up the support team in case of any issues anytime! Secondly, shared web hosting providers also started offering free goodies like free website builder, direction submission, andGoogle Adwords credit.
Moreover, just as every coin has a flip side, the cons of shared web hosting slowly came into picture. It is a bitter reality that, since multiple websites are hosted on a single web server, malware or any other problem can affect the other sites on the server. (The tech support team will rule this out, of course, but remember that it is quite possible just about anytime.)
As a result, the importance of dedicated hosting came into picture. Dedicated hosting, dedicated IP, added firewall protection, and miscellaneous proxy settings can help you a great deal in nullifying any of the ill effects propagated by other sites hosted on the same web server.
