Here are a few aspects that a hosting firm can offer to enhance a website’s SEO performance:
Hosting Location – in general, the closer the web servers are (geographically) to the site visitors, the quicker the pages will load because the greater distance between the web servers and the site visitors often results in more nodes for data to pass through. So if your website mainly targets North American users, it’s a good idea to find a web hosting provider in either USA or Canada.
Unique IP – when someone types in the domain name in the browser, the domain is translated into numbers which is the IP address and the computer is directed to that IP address. Every website on the internet is found not by its domain name but by its IP address. Normally there are two types of IP addresses: shared IP and unique IP. If your website shares an IP address with 1,000 websites and one of the websites is blocked or blacklisted by internet service providers (ISP), all these 1,000 websites will be blocked as well. In contrast, if your website has a unique IP address, you have an increased stability and reliability for your website. Even your website is on a shared hosting server and one of the websites on your shared server gets blocked by ISP, your website is still unaffected.
Optimize website - a lot of hosting firms offer a function called “optimize website” in their control panels. This function automatically compresses all the files before the files are sent to the website viewers. In such case, your website can be loaded quicker and acquire a better Page Speed which is a key factor of determining your page rank in Google.
With all being said, please note that all these mentioned aspects are only parts of the variables in the algorithms that search engine uses to determine the search results. Because the algorithm is not disclosed to general public, neither hosting firms nor SEO marketing companies can make any claims for guaranteed page rank for certain key words.
