I've been asked the question of whether if we should nofollow all of our social links, would this be a wise thing to do? I'm not exactly getting a clear answer from search results and thought you guys would be best to ask 🙂 Thanks in advance.

As title suggests we are running into a serious issue of the home page disapearing from Google search results whilst the rest of the site still remains. We search for it naturally cannot find a trace, then use a "site:" command in Google and still the home page does not come up. We go into web masters and inspect the home page and even Google states that the page is indexable. We then run the "Request Indexing" and the site comes back on Google. This is having a damaging affect and we would like to understand why this issue is happening. Please note this is not happening on just one of our sites but has happened to three which are all located on the same server. One of our brand which has the issue is: www.henweekends.co.uk

At the moment for most of our sites, we have both a desktop and mobile version of our sites. They both show the same content and use the same URL structure as each other. The server determines whether if you're visiting from either device and displays the relevant version of the site. We are in a predicament of how to properly use the canonical and alternate rel tags. Currently we have a canonical on mobile and alternate on desktop, both of which have the same URL because both mobile and desktop use the same as explained in the first paragraph. Would the way of us doing it at the moment be correct?
