12. Outgoing links from i do not affect q ji for any j!=I So by changing the outgoing links, a page can control its PageRank up to multiplication by a factor z ii =1/(1-q ii ) For 0<=q ii <=c 2 , 1<=z ii <=(1-c 2 ) -1 ≈3.6 for c=0.85
18. the PageRank of page j increases if if several new links are added then the PageRank of page j might actually decrease even if this page receives one of the new links. Such situation occurs when most of newly created links point to “irrelevant” pages.
