the page for users
without javascript.”

“…what does a like mean? Some
people like the page, some folks might
like the content, some folks might just
think it’s funny and likeable. As you
said, the likes are a good signal, but
they’re not a granular signal of what

expressing a like about.”

This is why people think the links pass value
Note: Google deliberately and carefully architected this to pass PageRank
They did so for a reason

lead to higher
Google web

causation”

“It was a complete
overhaul of the search
engine … they were going
to be able to handle link
data differently … they
could handle new social
signals they could not
handle before.
