Think of this document as a living communication between you and your client or boss. It is a document you should refer to often. It keeps all parties on the same page and aligned. I recommend sharing it in a collaborative platform so updates are shared between all viewers without having to constantly send out new copies (nothing sucks the life out of efficiency faster than "versioning" issues).
The leading search engines, such as Google, Bing and Yahoo!, use crawlers to find pages for their algorithmic search results. Pages that are linked from other search engine indexed pages do not need to be submitted because they are found automatically. The Yahoo! Directory and DMOZ, two major directories which closed in 2014 and 2017 respectively, both required manual submission and human editorial review.[40] Google offers Google Search Console, for which an XML Sitemap feed can be created and submitted for free to ensure that all pages are found, especially pages that are not discoverable by automatically following links[41] in addition to their URL submission console.[42] Yahoo! formerly operated a paid submission service that guaranteed crawling for a cost per click;[43] however, this practice was discontinued in 2009.
