Hi,
On my website (still not finished since there is always more to do

), I recently decided to put all the html code of my menu and footer in a javascript. This allows me to not have to paste the menu on all my pages everytime I change or add a category in my menu. That works great (only one menu definition, reduce size of pages) BUT I start to think that it may be a very bad solution for
SE Optimization...

: What would you recommend I should do ?

: Are javascript files a bad thing to use for an efficient SE spidering ?

: How important are internal links within a website ?
Please help, any advice ?
Thanks
