Search engines find and catalog web pages through spidering (also known as webcrawling) software. Spidering software "crawls" through the internet and grabs information from websites which is used to build search engine indexes. Unfortunately, not all search engine spidering software works the same way, so what gives a page a high ranking on one search engine may not necessarily give it a high ranking on another. Note that rather than waiting for a search engine to discover a newly created page, web designers can submit the page directly to search engines for cataloging.
Attempting to replace a dead link with your own is easily and routinely identified as spam by the Wikipedia community, which expects dead links to be replaced to equivalent links at archive.org. Persistent attempts will quickly get your account blocked, and your webiste can be blacklisted (the Wikipedia blacklist is public, and there is evidence that Google uses it to determine rankings), which will have negative SEO consequences.
Brian, I’ve drunk your Kool aid! Thank you for honesty and transparency – it really gives me hope. Quick question: I am beyond passionate about a niche (UFOs, extraterrestrials, free energy) and know in my bones that an authority site is a long term opportunity. The problem today is that not many products are attached to this niche and so it becomes a subscriber / info product play. However, after 25+ years as an entrepreneur with a financial background and marketing MBA, am I Internet naive to believe that my passion and creativity will win profitability in the end? The target audience is highly passionate too. Feedback?
Having an industry influencer publish a blog post on your site or turning an interview with them into a blog post can help to drive traffic both through organic search but also via that influencer promoting the content to their audience (see the backlinks section above). This can also help to add more variety to your content and show your visitors that you are active in your field.
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. 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 in addition to their URL submission console. Yahoo! formerly operated a paid submission service that guaranteed crawling for a cost per click; however, this practice was discontinued in 2009.
