Engine score setting: You can enter a
number in the Weight field next to each Engine to indicate
how important the engine is for your own needs. For example,
you can set "100" in Google and "20"
in AOL if you consider Google to be the search engine which
is more important than AOL for your business.
Position score setting: It has been set
for you by default. But you can always change the weight
setting to suit your needs.
