Heavy rank drop post migration

[vtmoz]

Our website has been migrated from Joomla to Wordpress at the end of 2015 and we have tasted the loss of 20% of the traffic. After an year at the end of 2016, we have relaunched the website in same word press with new theme.  Again we lost n rankings and traffic. I would say ranking. Because mostly people land on our website by searching for our brand. Now we almost went invisible for "keywords" we been targeting. We have checked all the possibilities like duplicate content, redirection, alt tags, speed, canonicals, backlinks, etc..and couldn't find what is hitting us. What could be such strong factor hitting us ?

What steps did you take during these website redesign to preserve your rankings? 301 redirects are often overlooked during site migrations, if you don't take time to map old pages to new pages, you've missed a massive opportunity to hang on to a lot of the rankings and traffic you had with the previous version of the site.

There's a great post on SEO preservation on the Moz blog from a few years back, I'd go through this list and figure out what was overlooked. You should still go back and fix anything you can, but it won't have nearly the impact it would have if the tasks on this list were done at the appropriate time.

Hi vtmoz. Did you change your domain name? Or just migrate to a different CMS?

Hi Dana,

We didn't change the domain name. Same domain name for last 10 years. Recently we migrated to same CMS (Wordpress to wordpress). Just redesigned the website and launched back
