So it is no surprise when Wikipedia article comes up high in google ranking. But occasionally a Wikipedia article will NOT be highly ranked, and will appear only in google 20-30+ or even further down the line . Any idea what makes Google dislike certain Wikipedia articles?
I don't think time should be a factor, google crawls Wikipedia very often, I've had new articles of mine appear in searches within hours, sometimes minutes, of being published.
One factor I know of is language, but for this question let's assume English language article, searched for using English language google front.
