Once you have written your website and posted it online, you need to get it indexed on Google. No doubt you have considered the SEO (Search Engine Optimization) of your site as you wrote it, but now you need to consider other factors, such as how your host server is going to affect your Google rank.
The web host consideration is often overlooked by webmasters, because finding a right web hosting is so difficult that it seems irrelevant. It is like finding the perfect car to pull the weight of your trailer without using too much fuel, only to be told that you should have looked for one that has flexible steel axles to take bumps and corners better.
In many cases, it is not how much your hosting company is going to push you up the search engine results. It is more about how much damage they can do to your ranking, including but not limited to, getting your website banned from the Google index.
IP Addresses
Many people think that having your own personalized IP address will help improve your Google rank. Whether this is true or not is unknown, but with a shared host you have to share your IP address with hundreds of other people. There are companies that you can often pay to give you your own IP address. Any decisive proof that private and personalized IP addresses helps your search engine rankings has been quickly denied by the bigger search engines, even though tracking the positive and negative actions from a personalized IP address would be easier for search engine bots.
Spammers
Shared
Banned Servers
Your entire server may be banned from a search engine. If you have VPS then nobody is to blame but yourself. On the other hand, if you have shared hosting then you could end up taking the fall (rankings wise) because of the actions of some other jerk on your server.
UpTime
Your server should have a very high percentage of Up-time. If it does not, then your website is going to have portions of the day, month, week, when it does not operate. Your rank on Google will not matter at all if your traffic is getting a “can’t find html” screen when they click on it.
The URL
If your host is not playing by Google’s rules, then the sites held within may be due for a serious knock to their Google Ranking. If the server has hundreds of URLs on it that are making it harder for Google to index, then Google may penalize the server, and therefore penalize your website along with it.
Final Words.
As I said hosting is very crucial for any business, because a bad hosting can encourage search engines to give low priority to your blog while giving SERP. So do proper research and read reviews about hosting before spending money.
