Welcome to the Q&A Forum

Backlino Guy is talking about a table of contents at the top of the article... See the gray box TOC on the left side of this wikipedia page for Philadelphia https://en.wikipedia.org/wiki/Philadelphia On-page anchor links with keyword hypertext, in my opinion, are second in optimization power only to the <title>tag.  One of the secret weapons of big article optimization.</p> <p>Hub-and-spoke is a multipage technique.  You have one main page for a topic... like Pennsylvania... and that page links out to many article pages about different cities, form of government, economy, parks, etc.   It is similar to a category page but is self-standing expository content.</p></title>
