We are working on moving our site to HTTPS and I was asked by my dev team if it is required to declare HTTP or HTTPS in the canonical tag? I know that relative URL's are acceptable but cannot find anything about HTTP/HTTPS. Example of what they would like to do Has anyone done this? Any reason to not leave off the protocol?

With Google figuring out how to make Ajax and JS more searchable/indexable, I am curious on thoughts or techniques to prevent this. Here's my Situation, we have a page that we do not ever want to be indexed/crawled or other. Currently we have the nofollow/noindex command, but due to technical changes for our site the method in which this information is being implemented if it is ever displayed it will not have the ability to block the content from search. It is also the decision of the business to not list the file in robots.txt due to the sensitivity of the content. Basically, this content doesn't exist unless something super important happens, and even if something super important happens, we do not want Google to know of its existence. Since the Dev team is planning on using Ajax/JS to pull in this content if the business turns it on, the concern is that it will be on the homepage and Google could index it. So the questions that I was asked; if Google can/does index, how long would that piece of content potentially appear in the SERPs? Can we block Google from caring about and indexing this section of content on the homepage? Sorry for the vagueness of this question, it's very sensitive in nature and I am trying to avoid too many specifics. I am able to discuss this in a more private way if necessary. Thanks!

We have a vanity URL that as recommended is using 301 http code, however it has been discovered the destination URL needs to be updated which creates a problem since most browsers and search engines cache 301 redirects. Is there a good way to figure out when a vanity should be a 301 vs 302/307? If all vanity URL's should use 301, what is the proper way of updating the destination URL? Is it a good rule of thumb that if the vanity URL is only going to be temporary and down the road could have a new destination URL to use 302, and all others 301? Cheers,
