As a web designer the way that I would increase the scannability of my web site is that I would make it as user freindly as possible. That is I would have my text in a good visible size as well as a non confusing font or text style. I would put my information in neat paragraphs that are not all jumbled toghether. That way anyone going on my page would be able to easily read my web page. Also I would make sure that I have the correct grid size, making sure it is a web safe grid size, so that everyone who visits my page can easily read it no matter what type of monitor they have.
