Hi web experts, this is the first time to post a new thread here, and don't know whether can post the link of my site here or not.
I have a old website built on 2012, it has been changed entirely from Aug. to Oct. of last year, except for the domain, the host, frame, content, urls, title tags of every page, product pictures, meta descriptions and keywords, have been changed, the purpose is for mobile friendly. Here please let me have two problems:
First, after the new virsion was published on the internet in Nov. if searched by site:www.domain.com on Google, there're so many SERPs of old webpages which appeared 404 if you open them.
Second, the SERPs of new webpages and old one, some of the title tags were changed by Google.
How can I do now?
