Web opimisation - bad spelling just has to go!

Checking the allthingsweb site position in Google for keyword phrases that I am targeting I was appalled to see that I am 4th worldwide for "website opimisation".

Thing is its dragging traffic in BUT I hate bad spelling so its just got to go.

Yes it will reduce traffic coming in to the site but on the other hand I'll be ensuring my site is perfect for users. So it's a toss up between bad spelling or traffic. For now I'll sacrifice the traffic (I'm such an SEO martyr!)

... now which client could I grab a testimonial from with this mis - spelling included from them, so I can keep it on the page??? ;)
