One of the most common problems is dissonance between your old website’s URL structure and your new website’s structure.
When it crawls your site, it expects to find those historical URLs as a base structure, with new pages regularly popping up in the expected areas (such as the blog and news section).If Google crawls your new site and finds that your old URLs are no longer present, it triggers a red flag, which could directly compromise your SEO.If your entire URL structure changed, it could be equivalent to starting a new site from the ground up, leaving you with almost zero residual authority, if you fail to properly 301-redirect all the old URLs to their new locations.Changes in your URL structure affect more than just your domain authority.There’s also a potential problem with the integrity of your external inbound links.
Whether you’ve manually built the links or not, there are likely hundreds of offsite links pointing back to various pages under your domain.
If the URLs associated with those pages suddenly change without proper redirection, those links will no longer point to a relevant destination.
Not only can this cause your rankings to plummet, it can significantly decrease the amount of inbound traffic you get from referral sources.
If you can't change your browser because of compatibility issues, think about installing a second browser for browsing and keep the old one for compatibility.
Ask your admin to update your browser if you cannot install updates yourself.
Maybe you’ve updated your brand, or you’re looking to roll out a new product line.
