Periodically, we profile a Blogger partner that can add functionality to your blog. This week we'd like to spotlight Lijit, a company building "search powered web applications for publishers" (that's you!). Lijit has made adding its "wijit" as easy as could be—just fill in your blog's URL and complete the sign-up wizard, you'll be good to go.

What does Lijit give you? For starters, Lijit provides a nice search tool for your site that will not only search your blog, but search the blogs of your friends, and all of the related sites (Flickr, YouTube, Picasa, bookmarks, etc.) that you and your friends use regularly.

Where Lijit shines is in the stats they gather for you: what are people searching for when they come to your blog? Once they arrive, what do they then look for? Where are they coming from? How has search traffic changed over time?

Best of all, Lijit lets you expose this info via a customizable "wijit" so that your visitors can see where other visitors are coming from and what they are looking for. To see this in action, take a look at Dark UFO's Lost Spoilers site, a Blogger blog focused on unraveling the mysteries surrounding the TV show Lost. The Lost Spoilers wijit shows not only the most recent searches that have brought visitors to the Lost Spoilers site:

It also shows a map of their visitors:

And finally it shows a list of the most recent visitors, their locations, and if they used a search to visit the site, the search term they used:

Interested? Give Lijit a try - just visit their site and you'll have it on your blog in just a few minutes!
