Reality bites. You could draft up an amazing strategy, bright-eyed and bushy-tailed, to which you're rebuilding an entire category structure of one of the website's most lucrative lines... only to find out there's a ticket queue for the necessary resources that's more than 6 months long. Despite your brilliant idea, you're going to look bad when the client calls you out on not understanding their business.
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.
