Having read the new "Best Practices Guide", I can honestly say that I know less than I did before.
Perceived correct practices have now been replaced with "Arbitrary and Subjective" guidelines.
No. The dichotomy between Google Search and Google AdSense has NOT been resolved. Not by a long shot.
Maybe the "steel wall" between Search and AdSense in not such a good idea, because of the conflicting interests of the separate entities. Google needs to present a coherent, consistent protocol for webmasters, which they are not currently doing.
Search wants to optimize user experience.
AdSense wants to maximize Google income.
These two objectives are not compatible, and have never been.
Will they ever be?
Will Search ever say, "Let's fill every page with ads?" No.
Will AdSense ever say, "Let's cut Google revenue for esthetic reasons." No.
There you go. No resolution will be forthcoming, IMHO, as far as I can see.
