I own a car shipping business (www.carshippingcarriers.com) and I was ranking very high last year, but around the end of August our site lost a TON of rank. Afterwards I had my SEO team at the time (no longer working with them) do a complete overhaul of the website (rewrote content, combined many pages together so no duplicate content issue, made it mobile friendly, etc.. Since then we continue to still lose rankings on Google. Yahoo and Bing seem to keep performing decently, but Google we are getting destroyed.
I have been a member of Moz for a few months and I have been using the open site to check my competitors and their linking profile. One in particular, www.joescarshipping.com, has been ranking extremely well and the site looks horrible, doesn't have many links, hardly a social media presence, etc.. Compared my my website which has ton of content, articles on our website, social profile is great (tons of Google+ usage), not a ton of links so a decent amount of links, etc.. Why would a company like that be ranking so high while I keep falling?
Any advice or reasoning as to what is wrong or what could be done to get better rankings? I am just at my wits end on this matter.
