Instead of using javascript, will adding a title tag within a div help with SEO and accessibility?

I think you may have some traffic loss in the short-term, but over the long term, you ought to be able to get the site traffic back up, especially if you point the old domain to the new subdomain, along with related 301 redirects for individual pages, if you keep the same or a similar site structure. I happened to have read this earlier today. "Keep in mind though that subdomains may not fully benefit from the link equity, positive metrics or rankings from the main domain they are associated with and vice versa, if Google thinks of them as being under separate ownership. For example, a blog on blogspot.com does not benefit from the authority of blogspot.com. That said, if you already have content on a subdomain, it’s worth noting that the effort and consequences of moving that content to a root domain is typically not worth it, unless you spot an issue that compels you to do so. (If you do decide to move the content from a subdomain to your main domain, a short-term loss in traffic is typical.)" Via Moz's Top 10 newsletter: https://www.stonetemple.com/subfolders-subdomains-microsites-and-seo/ So, I think you need to fully evaluate the value of moving to a subdomain over staying on a 2nd level domain. -- Jewel

Hey Shirley - Thanks for the question! Short answer is no - the information does not have to be different. What should happen with a canonical is that the search engines will see the canonical and apply the ranking for Page A to Page B. However, the search engines do tell us that a canonical is a suggestion and that they do not always respect it if they think it was either a) done in error or b) is being done to manipulate. So, assuming Page B really is a duplicate of or a better version of Page A, yet you want to keep Page A around for some reason (PPC landing page or other), then the meta info will likely be similar anyways. Finally, if you are canonicalling Page A to Page B, make sure that Page A is not in your XML sitemaps! Good luck! John

I don't really know any best practices in this topic. Me, in your case, I'd leave them just as they are now. Applying the canonicals, of course.

Thanks, Eric!
