When you do find bad web hosting reviews, it does not mean that you need to discard the hosting company. You need to read the full review to find out what the bad review is really about. This is when knowing what you want from your website will come in handy.
You need to compare the reviewer’s needs with your own. If the reviewer has brought up something specifically that you know is a requirement for your website, then it can be safe to say that you will leave a bad review too. However, if it is not something that you would ever consider needing then you need to move on from that review.
If the bad review does not go into any specifics then you should see if there is a way to contact the person that wrote it. Your best way to find out the problem is by asking the person directly. You never know, you may actually find that it was the reviewer’s fault and that the terms and conditions were not read correctly.
