I have a wordpress blog. Previously it was hosted at xxx.wordpress.com. Wordpress.com has a feature where they allow you to customize the URL -they call it connecting to another domain - so the URL becomes yyy.yoursite.com. I did this and all of a sudden my traffic has dropped by 50% or even more. Most of my traffic comes through Google. It has been about 2 months and the traffic has still not recovered. All previous links work. When someone tries to access a page under xxx.wordpress.com they are just redirected to same page but under yyy.yoursite.com. I also updated the site address in Google search console. This is really puzzling for me because why would a internal change like this affect my search results. If I hadn't told Google that I am changing the site URL, it would have continued to show the results. It seems telling Google that I am changing the site URL did more harm than good. Has anyone run into this and can explain me the cause and if there is anything I can do to restore the site traffic? I am not expert in SEO. Thanks.
