Take the 10 pillar topics you came up with in Step 1 and create a web page for each one that outlines the topic at a high level -- using the long-tail keywords you came up with for each cluster in Step 2. A pillar page on SEO, for example, can describe SEO in brief sections that introduce keyword research, image optimization, SEO strategy, and other subtopics as they are identified. Think of each pillar page as a table of contents, where you're briefing your readers on subtopics you'll elaborate on in blog posts.
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.
SEO is short for "search engine optimization." To have your site optimized for the search engines means to attempt to have top placement in the results pages whenever a specific keyword is typed into the query box. There are many search engine optimization services to choose from, so here are some things to keep in mind when seeking SEO services or developing an SEO strategy of your own.
Great post. I know most of the stuff experienced people read and think “I know that already”… but actually lots of things we tend to forget even though we know them. So its always good to read those. What I liked most was the broken link solution. Not only to create a substitute for the broken link but actually going beyond that. I know some people do this as SEO technique but its actually also useful for the internet as you repair those broken links that others find somewhere else.
