Hello, we currently use WordPress and WooCommerce to display our company website for marketing and products/checkout. We used to use NetSuite's SuiteBuilder for this. One thing that is an issue to us is that when we do a google search for our products we can still see and navigate to the old site using the NetSuite url. Anyone know how to get the old site from showing up on google searches?

There may be a slight SEO advantage in picking up the old Netsuite domain URLs and redirecting them to their equivalent on your new site. Assuming you have the functionality in your account still, you can do this with Setup > Sitebuilder > Redirects. I'd pick up as many as possible, leave things to settle for a month or two, then add a robots.txt file in your Website Hosting Files > Live Hosting Files (or equivalent) to block all further indexing, ie.
