It might be advisable to move the donation message somewhere else, since
it is included in the Google summaries, leaving only very little room
for lines from the article that are relevant to the search term.
The Google result for "Otto Rank" for instance looks like this:
=====
Otto Rank - Wikipedia
Otto Rank. From Wikipedia, the free encyclopedia. Find out how you can help
support Wikipedia's phenomenal growth. ... External link. Otto
Rank.com. ...
=====
Not all Google results show the donation message, possibly because they
haven't been indexed recently.
The whole repetition of "Otto Rank. From Wikipedia, the free
encyclopedia." is redundant. Maybe it is possible to add "the free
encyclopedia" to the HTML title of the page, and then reorder the
contents so that Google will pick up directly at the first sentence of
the article (which will typically contain the search term).
