This has probably been discussed before but:
If you moved the Javascript code in to an external file and called
it in rather than having it on the page itself it would reduce the
amount of code on the page, which helps the spiders decide what is
content and what is code it should ignore. There is a number after the
Javascript that has been found to be quite lengthy, so if you have
several scripts on your page it may only be worth moving one off in to
it's own file
