Here's a surprisingly basic question for you: Do links to page A (about widgets, say) improve the page rank of page B (about gadgets) from the same site?

Let's take StackOverflow.com as an example. The general quality of information on SO is quite high. Let's say there are two questions (pages) on SO, one about Javascript closures and another about C function declarations, and that there are hundreds of links to the "Javascript closure" page from other sites. Naturally that will (eventually) improve the rank of that page when someone is searching for "Javascript closure". But does that do anything to improve the page rank of the C function declarations page if someone searches for "C function declaration"?

E.g., does a domain have any kind of general reputation in the algorithms of search engines? Or is it all "about the page, baby, all about the page"?

  • Actually, Nathan, People have discovered how Google works, but they have several algorithms that determine how pages are ranked. Google uses a system called PageRank, or they did, at least, that will rank pages based several factors. If you figure out how to abuse this system, they will change it. Ste4lth almost 9 years ago
  • Doug, I politely disagree: SEO is a major part of web design. If this were a car manufacturing Q&A, would we throw out questions about marketing cars to dealers? We have to consider search engines to be one of our audiences as well as real users. Sean Maher almost 9 years ago

A domain has almost no bearing on the rank. It's primarily based on content and how many pages are linking to that site, and based on how many visitors visit/click the result. Different search engines work differently but Google is the most complex, since it's based on several different factors.

  • So you're saying no, page A's quality (as measured by links into it) does not affect page B. T.J. Crowder almost 9 years ago

Do you mean if page A links to page B and page A has a hundred pages that link to it? Do those links flow upstream to B to increase it's rank? If so I would say no; generally it's how many direct links there are to a page that increase it's PageRank.

  • No, I'm not talking about any cross-links between the two pages. Just that they're in the same domain (er, and probably each has links to some common area, but that's a lesser point). T.J. Crowder almost 9 years ago
  • Sorry, not the same domain, but subdomains of the same domain. T.J. Crowder almost 9 years ago

There is a little evidence that domain does (sometimes) matter: If there is a wikipedia.org article which matches the search terms, it will be a top-10 (usually top 3) result even if the wikipedia article is only 24 hours old. (Also, wikipedia's version of an article always seems to outrank any wikipedia mirrors, although the latter usually aren't as fresh as the original). This may well be because google has a specific exception built into its algorithems for wikipedia and selected major domains. (I note that using a page rank tool on a wikipedia article returns n/a).
