To me it doesn't seem that easy because a page is usually optimized for just one keyword ?

I think that if a page is truly optimized for the word "tennis" then it would be better to link to another page that is related to tennis (e.g., rackets, tennis balls, tennis tips) than it would be to link to a page that is optimized for golf.

Conversely, if you want the Golf page to do well, then it is probably a good idea to create pages that are related to golf and have those link to your golf page. Maybe that way google will see your site as an authority on golf, since you will have more than just one page on golf.

Just my two cents...
