In a recent issue of Doctor Ebiz, I said that both banners and
links increase link popularity. Though this is correct, reader Tim Jones
makes an important point on how Google evaluates incoming links:
"Google uses the textual words in the link as part of its relevancy/ranking
algorithm to determine how important that link really is." -- Tim Jones,

So, for link popularity purposes, banners are good but text links that
include relevant keywords are even better.
