Welcome to the Q&A Forum

One alternative to the "noindex" directives described below is to instead implement a canonical link tag to an alternative page you would prefer to be indexed for the same content. This would only be relevant if there was another very similar page. And, it would not be as strong of a directive as the "noindex", so I would not use canonical if it's extremely important that it not be indexed, like perhaps some sensitive info. If you do go the NOINDEX route, then I would suggest, after you verify it has been properly implemented, to use the removal tool in Google Search Console. It technically isn't needed, if you have the NOINDEX directive, but it is usually recognized more quickly, and won't conflict. And then, once the page is out of Google's index, the next step (and only after it is removed and has the noindex tag), is to disallow crawling of that page in your robots.txt file.

Thanks for the quick response.  If that is the case why is there a sub-domain option?  Is it only to have the ability to see linking domains and links?  Not to have the ability to see authority?  I then typically default to page authority to have a sense of the authority of the sub-domain.

Thanks Dave

Yes, this is potentially a serious issue, especially if you rely on the canonical to point multiple versions of a page to a single page for indexing purposes. The canonical URL should have a full protocol, domain, and path. If you're using Wordpress, take a look at the Yoast plugin, for injecting canonical links.

Domain Authority is a score (on a 100-point scale) developed by Moz that predicts how well a website will rank on search engines. It is made up of an aggregate of metrics (including general link profile, quality and quantity of links, and more) that each has an impact on this score. It can be difficult to directly influence your DA, but one way to move toward increasing it would be to improve your overall SEO. A great place to start with that could be to focus on link building! You can learn more about link building here and get a more detailed explanation of Domain Authority through this resource. In general, I'd recommend keeping in mind that all of these metrics are relative with respect to the other sites included in our index. The metrics will probably have some additional context when compared to sites similar to your own, including your competitors. Feel free to give those resources a once over to see if they help clarify some of your questions!

If you and your server do not have a backup of your website, it is complicated. You can try to recover from Web Archiver as you have been told, but you probably won't have it complete. Also it will be created with some CMS type Wordpress reason why you will have lost the data base, in addition to the subject, etc. What hosting does not have a backup of at least a week?

Don't worry, Google will take some time. you can also submit indexing request manfully.

Dude, if you're just coming to this forum to drop links to your site, I don't think anyone is going to take your work in optimization seriously.
