Losing over 30,000 uniques basically over night I got worried and started looking heavily into why this has happened and what I can do to fix it. I immediately dove deep into my backlink report and noticed that our referring domains were at about 2000 back in May and that is when we jumped up to number two. But in October that number had dropped down to about 1500 so first glance I figured that was the problem. So we got back on the link building and brought our link count up to 2600 referring domains and added some good authority links along the way. Didn't see any change in the rankings.
So then I went to content, I completely redid the page that ranks for these keywords (Aircraft for sale and Airplanes for sale). After recreating this page, page load time is way faster, better internal links on the page, less scripting, and more content. Still no change in the rankings.
Our content in this section of the website is always changing and updating due to the nature of our business. I do know there are some on page meta stuff and htag stuff that needs to be worked but I have gone through and updated that and changed it several times and just decided to go back to what it originally was when we ranked well.
I need some fresh eyes to take a look at the situation and point me in the right direction so that I can get back up to the number two spot so I am in position to start fighting for the number one spot. Any help is greatly appreciated and thank you.
