John Mueller: "if it's not nofollow... then we can forward the PageRank we have there."
1. My G+ SEO principle: Apply basic rules, don't create new ones.
2. Facebook and Twitter down. That just leaves... "Oh! It's us."
3. A year later, I talk with John Mueller & confirmation arrives.
Following are just some of the Google Plus SEO principles I've written about, or will yet cover, that are important to explaining how & why my ideas about G+ ranking work. Many of these are common formerly known principles of indexing, ranking & passing authority within Google's Search index. Then based on my observations (now it's confirmed knowledge) that Google indexes G+ content & ranks it the same as any other, I have applied these ideas to my following Google+ ranking principles.
1. Google's index algorithms treat Google+ Profiles, Pages & content like any other site on the web.
2. Google+ Profiles, Pages & Posts, pass / receive PageRank once indexed by Google Search.
3. The effect of Google+ links on search ranking? "We treat that as any other link that we can find."
4. The index passes appropriate PageRank to Google+ content by the same follow or nofollow rules.
5. Any Google+ profiles, pages & content not indexable (ie. set private), will not pass PageRank.
6. Google Plus does not have, nor give, authority of itself at all.
7. The authority given and received in Google+ comes from people (in the form of shares/citation).
8. Google bots reach & then follow on from Google+ content just like any other web.
9. Crawling is done by spiders who like to crawl on webs, they don't like orphaned dead-end pages.
10. Google+ content is not parsed and then ranked in Google's index by independent algorithms.
11. We don't have to test/theorize about new G+ algorithms, this all happens in the current indexing.
12. Plus 1's are not a ranking signal, but can help find content if +1 pages are public (indexable).
13. I was wrong insinuating earlier that G+ PR might not be "extremely similar." The PageRank throughout the web & Google+ are actually one & the same, what my wording should have emphasized better is that, it's only the G+ structure that's different.
While I'm discussing PR here, let's not forget that traditional PR would be associated and passed on based on particular pages, but G+ [profile] streams are not pages at all. So we can presume they will have similar results, [Emphasis here for what I meant] but obviously the structure would be different. I also think that PR has evolved considerably and comments Matt has made [regarding Penguin & Disavows] also prove it, within the last year, or so. [Crossed out as inaccurate]
And I'm bringing this up about the structure of the G+ unidirectional stream being quite different than traditional webpages as a point of note, because I'll be explaining in another article why this also causes considerably different behavior in G+ post search ranking from traditional pages.
So how did we get on this story of PageRank in Google+ & its significant implications for SEO?
