If you are understanding deeply the title may be you will find the secret message that already hosted in my mind 
. Yup, it looks for best web hosting server and not best web hosting offer. May be best web hosting offer is connected to it’s price, and best web hosting server is about it’s performance. So here is my experience in some days ago ( it just around one week ago).
I have got good offer for vps webhosting 3 months ago, it’s price is good for me, and also it’s connection performance is good also, but at the near some day ago I investigated that my some sites which hosted on that vps webhosting are difficult to be indexed by search engine! I don’t know but it is real and happen to me. Then I decide to look another web hosting server, finally I have got one.
How to know your web hosting server is good? may be you can follow my steps. Here are my steps:
Step 1:
Look offer that has good connection ( you can ping or download test and what so ever).
Step 2:
This is important. I have used wordpress for my some sites, to test that your web hosting server is good so you have to post an article. If in some minutes your fresh article is indexed by google then your server is Rock!
