does it matter how the link looks that the anchor text is pointing to? like for example: anchor text: finance link: http://www.yahoo.com/FINANCE anchor text: finance link: http://www.yahoo.com/finance does it make a difference to google robots?
Case does matter to some extent, but not a whole lot. Here are two examples one with "Shoes" another with "shoes" http://www.google.com/search?hl=en&q=Shoes&btnG=Search http://www.google.com/search?hl=en&q=shoes&btnG=Search You can see there are some difference on SERP.
