Hi,
We are running a website in Spain to teach touch typing to children (www.mecanografia.com). Our main keyword is mecanografia (touch typing in Spanish) which is official written with an accent on the i.
Our SEOMOZ on page optimization report was initially an F because we set the keyword mecanografia without an accent and on the page we use the grammatically correct version with an accent on the i. Once we added the keyword with accent to SEOMOZ our rapport was upgraded to an A.
Our question is: how does Google treat accents. Is it necessary to optimize for words with and without accent or does one version suffice. Users search about 50% of the time without using the accent.
Any advice is greatly appreciated!
