Last week, Google unveiled the latest must-have tool for every online campaign operative - Google Browser Size.  Upon entering the URL of your choice, Browser Size pops up an interactive overlay showing you what percentage of web browsers are able to view which sections of your site.  This comes in very handy when your campaign is trying do decide where to place a donate button, an email sign-up box or a highlighted video.

To demonstrate the power of Browser Size, I analyzed ChuckDeVore.com using the Browser Size tool:

By plugging ChuckDeVore.com into Browser Size, we are able to determine that DeVore's email sign-up box fits completely in 95% of browsers without the user having to scroll. 

Clicking through the splash page onto DeVore's homepage, we find that the "DONATE TODAY" pop-up button falls slightly down the page, viewable in 90% of browsers without scrolling:

Both DeVore's email sign-up page and donate button appear to be in easily viewable locations, increasing the likelihood that his supporters will submit their email addresses and/or donate to his campaign. 

As Browser Size can show you, moving critical components of your campaign's website just a few hundred pixels can have serious implications.  Take a look at Alan Grayson's campaign website, which has undoubtedly received a great deal of traffic ever since his "Die quickly" moment in late September:

Browser Size shows that less than 40% of Grayson's website visitors can see the entire "CONTRIBUTE" button.  If 100 people visit Grayson's site, 60 of those 100 can't see his contribute button!  That's an astounding number that should alarm any candidate, but since it's Grayson, I'm not too concerned.

What percentage of your website visitors can see your donate button?  Find out at browsersize.googlelabs.com.
