Snap.com, a fairly new and interesting looking search engine, is offering website and blog owners a handy little device. (Thanks to John Battelle at Searchblog for pointing this out.)

The tool is called Snap Preview Anywhere and allows a surfer to hover over any link that has been enabled by this service and see a very nice visual window of what the page they might choose to surf to looks like.

Here’s a page I am building to promote my book that is due out in about 6 weeks. Duct Tape Marketing – The World’s Most Practical Small Business Marketing Guide. (Hover over the link and you can get a quick view of the page.)

Adding this feature to your website is simple and free – just add a line of javascript code provided by snap when you complete the sign-up process. Tools like this won’t make or break your blog, but I think they add to the overall experience.
