What is PR4 PR8?

Nobody was born knowing any of this stuff! And in many cases, there's an industry of people making a living out of it by exploiting the fact that many "beginning marketers" aren't quite au fait with it all.

Page rank seems to be of less and less importance with every change made to Google's algorithms, both the big, publicly announced/debated ones and the other, smaller, continually ongoing ones.

One can see this for onself from - among other things - the regularity with which lower-PR pages (often with fewer backlinks) outrank higher-PR pages (often with more backlinks) in Google's SERP's. SEO these days is increasingly about quality and relevance. Numbers of backlinks alone, and especially page ranks, are actually pretty unimportant. And gradually getting less important, too. Google says that's intentional, and will continue. Meanwhile, a lot of backlink sellers (some of whom call themselves "SEO consultants", these days - you can imagine) don't like this being pointed out, for obvious reasons.

I'm among many Warriors here who keep saying that we'd be delighted if Google just abolished page rank altogether rather than continually devaluing its significance further and further all the time. (Don't think that will happen, though!).

Woah Diana no, no, no!

No one starts knowing everything. I know, I've learned a lot from my mistakes.
