On page report card for the keyword "computers"

[seoanalytics]

I was looking at which websites ranks in the TOP 3 for the keyword "computers"...

I noticed that first is wikipedia and then there are Dell and Apple...

I then did an on page report card and I noticed that wikipedia has a grade A (which is great )

However, Apple has an F ( which sucks !! ) but there still rank out there.

My question is why is Apple ranking for the keyword computers with no tiitle, no URL, no H1, no body, no B/Strong... when wikipedia has all of that and the term " computers " occurs 290 times on its page...

Is is due to the fact that apple has millions of external links and is that enough to rank even with an " irrelevant " page ?

By the way I have noticed that on other keywords such as " bicycle ".

Wikipedia is ranking 1 st and then sites like www.trekbikes.com are out there but they shouldn't based on their homepage "optimization ".

I know there are other factors but I am just trying to figure why such sites ( like apple or trek bikes ) rank out there.

Thank you,

Links and page authority. I'm sure that is the main reason.

The website apple.com has 6,028,446 backlinks. It has 23,558 rankings in Google's organic results, a Link Influence Score of 100% to the website. That means that links from apple.com have an extremely high influence on the search engine positions of the linked sites. Plus, having a page rank of 9 doesn't hurt either.

That is what I though. However, is the on page optimization only valuable for long tail key phrases that are not requested very often ?
