I have listed a few important points you may need to consider before signing up for web hosting.

1. Look at how much uptime the web hosting site can provide.

2. Look at the amount of webspace, bandwidth. If too little, don’t bother to sign up with that web hosting company.

3. Check whether they offer any money back guarantee in case if you are not happy with the web hosting company. 

4. I prefer 24-7 technical support

5. How long has the web hosting company been in the hosting business and read any reviews. 

6. Do they provide (reasonably) latest versions of scripts such as php etc….
