Switched Web Hosting Provider, 50% drop in natural traffic

how to track the problem?

[Future]

Hello,
We moved from Host A to Host B 2 months ago and this has resulted in 50% drop in natural traffic.

How can we find the correct answer for this ?
We have done following changes to site.

1. Switched from apache to litespeed webserver
2. Changes the old nameservers from .NET TLD to hosts nameservers.
(according to dnsstuff there are no errors with domain neither problem with the new IP)

How to further debug this issue ?

Regards,

Some questions which might help to find the problem:

• Did your traffic drop instantly after the hosting change or gradually in the last two months?
  
• Are there any errors in your server log files?
  
• Did you see a significant drop of rankings or number of indexed files in the search engines?
  
• Does Google Webmaster Tools give any errors, a lower crawl rate or other information which might indicate a problem?
  
• Is the new server in a different geographical location than the old one?

A few questions. Does your site get a lot of "long tail" traffic? Is most of your organic traffic from Google?

If you answered yes to either, you may want to read the following thread:

Google made some big changes to their search algorithm in late April and it has taken its toll on a lot of website owner's organic traffic.

It could be coincidence, but perhaps your traffic loss has nothing to do with your host migration? I assume none of your file names or urls changed right?
