Traffic dropped suddenly

[HasitR]

-In early January 2013, we had to switch servers after many years with the same one.  We were highly ranked and getting about 8500 unique visitors per month.  -We didn't notice the traffic falling because we were focussed on a major site redesign and addition that we launched in April 2013.  Visits continued to fall, this time also because the company that launched it didn't double check their work and had some dead links etc.  Those were all fixed by approximately June 2013.- early January 2014 we switched servers again because we were afraid the new server we moved to was perhaps ranked poorly or was possibly a spamming site before.  Currently, nothing has changed.  What was about 8500 unique visitors per month 18 months ago, is now about 1,000 and no leads are coming in at all.

Hello Hasit, and welcome to Moz!

This might be a tough one to diagnose without someone spending a decent amount of time looking at your site, your analytics, your backlinks, etc, but the Q&A community will do what we can to help.

First, can you give us a URL at all so we can look at the site?

When the major site redesign happened, do you know if any redirects were put into place so that people still got to the right pages if URLs changed?

Is the site verified in Google and Bing Webmaster Tools? If so, are there any notices there about any actions taken on your site, or problems crawling your site?

Your traffic has dropped, but from which sources? In your analytics, look separately at traffic from search, direct traffic, and referral traffic. Did you have some links that were bringing in good traffic, and those sites removed the links? Is the traffic down from all of the search engines, or just one search engine?

Have there been any other general changes in the marketing of the site, or in your industry as a whole? Maybe TV advertising stopped, so fewer people were looking for your site, or email newsletters stopped, or paid spend was reduced in AdWords?
