1.           Reliability: This is not of moment you can fully distinguish by just looking at their website, in consequence you'll have to obtain a works of research. It's always an applicable idea to finish a search about the host to find any reviews from past or current clients, or you can even take a step further, by reviewing the support forums of the host if they have one. There you can easily find as much information as you need. How does this help with regards to reliability? Simple, it can show how fast they respond to complaints and issues by reviewing what past or current clients have said, and postings in the forums can show how they handle customer feedback. 

2.            Cost: We are all looking for a value hyped up deal. It's wanted that we influence in style now market price when election a fired server host. Selecting a $29/month server may not be the top option if it's backed with poor support and perhaps your server built with recycled hardware. Take note, this is not saying that cheap dedicated server hosts produce low quality service, but I'm saying that in 8 times out of 10 you do get what you pay for. Do price shopping and take note of each host's price along with their server specs, bandwidth, network, and support guarantees. Review each and then you'll be able to figure, which one is truly the most cost effective. Is it worth it to have a $29/month server with only 256 MB RAM which may be slow and unresponsive if hit with a spike in traffic? It's going to be up to you to weigh those options. 

3.           Support: This is toilsome for issues agnate as downtime, ddos attacks and characteristic issues dealing with your server. It is foremost that you express with the help team before purchasing a server. Why? Simply for you yearning to demur their response before investing any funds. If you would rather not send an email or call before making your purchase, if the site you're thinking about has a support forum, you can register and post your technical question there or review the questions asked prior to get a better idea of how solid their support technicians are with regards to answering questions. 

4.           Longevity: This is usually not listed as a bearing as manifold start-up fired server companies are solid, but it's usually an elite risk to lane the twist of cut that a transaction has been in business. You can seal a whois of the host's domain name to see how long a host has been in business. It can be a good indication that they're in for the long haul if they've been around for a while. This is not to discredit choosing a new company, as many solid server hosts are started regularly who go on to be huge successes. Simply use your best judgment when reviewing if to go with a host that's been around for years instead of one that's now getting started. I should point out here, that in some cases newer hosts will fight harder for your business and give you an overall better support in the beginning in some cases as they really treasure your business. It's really a toss up here, that's where your natural instincts for decision making will have to be the deciding factor.
