If you use Google Analytics, you'll recognize this as the basic navigation bar from your dashboard. Click on "Traffic Sources" and then on "Keywords," and you'll see a list of all the words and phrases people used as search strings when they were going to your website.

So, we can see that -- in addition to more obvious things -- someone typed "technological ineptitude" into Google, saw the page below, and clicked through to my blog post about
making your website friendly to less tech-savvy people. More than one person, actually. I never aspired to be #6 at Google for "technological ineptitude," but I am, and people come visit me after typing that in. I don't pretend to know what they were looking for, but I hope they found it here.

The keywords are listed in order of frequency -- that is, the number of people who typed in that word or phrase at a search engine and then clicked on your page. Within a particular frequency, they're alphabetical. So all the phrases that fourteen people used will be together in alphabetical order, and then all the ones that thirteen people used, and so on.
While there can be some amusement value (I'm still wondering why that client of mine has "bar pizza" in his GA keywords list), you can actually learn some very useful things from this metric in your analytics.
Take the case of
Courtney and Wise, upscale Sydney house painters. When I started working with them, these were their top ten GA keywords for a week:

While a few people found them by looking for "painting services," after that they were getting visitors who wanted information about art. The person looking for "animal art" or "art easels" isn't looking for someone to paint a house.
Here's last week's top ten:

While the folks looking for "house painters, usa" aren't Courtney and Wise customers, the great majority of people reaching the website now are looking for the business, or for house painters around Sydney.
There are a lot of lessons here. The first is that simple traffic doesn't tell you enough. Of course you want traffic. Increased traffic is pretty much always a good thing. However, Courtney and Wise could have thousands of people visiting them while looking for art over the fireplace, and expect very little new business.
By looking at their keywords, I could see that they needed a much tighter focus, and much more relevant, targeted online marketing strategy, to make their website useful to their business.
By looking at their keywords now, they can see that we've succeeded in accomplishing this. If we hadn't, then we'd know we ought to do something different for them.
If you use a blog, your keywords can tell you what topics are most useful to your readers, or most successful in reaching new readers via search. You can see below one week's top keywords for my
lesson plan blog. People reached my blog that week through about 2500 different keywords, yet it's pretty clear that fairy tale lesson plans and activities were a favorite.

Fairy tales are always a favorite for the blog in question. So, while I write there about everything from science to classroom technology to music, I make sure to keep fairy tales a frequent topic. I also make sure to keep those fairy tale lesson plan posts updated, with usable links and so on, since they continue to bring me traffic for years.
If for some reason I wanted to change the focus of that blog and bring in different kinds of traffic, keeping an eye on my keywords would allow me to fine-tune my efforts and make sure that I met that goal.
You can also search for a particular word within your results -- handy if you have thousands of words and phrases on the list. Since people might approach a topic from a number of different angles, it's good to be able to find all the variations. So, when I wanted to know whether people were looking for lesson plans using Sketch Up, I was able to answer my question even though folks used phrases ranging from "Sketchup lesson plans" to "class activities for google sketch up." Knowing that there were some people interested in the topic told me that it would be a useful topic to write on again.

Your GA keyword list can give you even more specific information if you use the "Dimension" menu. Click on a particular keyword from the list, and you can find out more about how people used that word. In the example here, we can see that a high proportion of people using one particular keyword this week were from Indianapolis. Seeing this, we want to find out -- if we don't already know -- what happened in Indianapolis this week to catch so many people's attention. Whatever it was, we'll want to repeat it.
Explore your keyword list some time. You may find, as I did, that people visit you with surprising things on their minds -- not just technological ineptitude, but "2 scary things" and "strategies for avoiding piracy" are on my list -- but you'll also get some useful information.
