Clicktale offers advanced filtering options, which you can use to sort visitors by actions, locations and more. Here's a range of filters you will play with:
Dates - select dates or date ranges for recordings. Useful for comparing user activity after redesign, new copy or other site improvements.
Page Viewed - view recording by URL or page popularity.
Referrer URL - see how various referring URLs affect visitor behavior. Filter by Google, Yahoo, Live (and other search engine) or by banners/links/adverts. See the difference between search engine users and users who come through referral links or advertisements.
Visitor Activity - here you can find more granular measurements.
Tags
Click Count - filter videos by number of clicks, from 0 to 80. Useful for monitoring engaged users, who are more likely to deliver conversion.
Mouse Move Count - filter videos by number of mouse movements, from 0 to 400.
Scrolling Distance - see visitors who scroll a percentage of the page from 0% to 101%. This can be an indicator that the user is reading the page, but you have to add a minimum time limit to truly filter out readers, since the majority quickly scroll down to the bottom of the page, just to check what's there before hitting the back button or clicking away.
Demographics - useful for tracking users who are a part of your targeted geographic area, for comparing visitors from different cities, and clearing out irrelevant traffic.
Countries - filter out irrelevant countries if you're limited nationally. Compare user behavior from different parts of the world.
Languages - do French speakers browse differently from the English population?
Browser - I don't think the browser affects user behavior, but I might be wrong.
Platform - Windows, Mac, Linux, Mobile.
Time Zone - does user behavior differ with timezones? Find out.
IP Address - more advanced, as you can filter out by cities.
Intervals - this section of filters has some really powerful features, like visitor active time, page count and more.
Visitor Active Time - track visitors who only spent X amount of time on your website. Perfect for filtering out "accidentals" and leaving only serious customer prospects. Keep in mind as much as half of the traffic is usually not interested in buying, while the other half is at different stages of the buying process.
Visitor Open Time - from my understanding this measurement only shows videos of visitors who keep the page open for X amount of time. Range is 0 to 90 seconds.
Visitor Page Count - sort videos by number of pages visitors view in a single visit. Useful for sorting out serious prospects, as conversion requires at least a few page views (lander > another page > checkout/application > thank you, etc). See where visitors stumble in the conversion process.
Page Active Time - this filter will show only visitors who spent X amount of time at a specific URL.
Page Open Time
Page Load Time
HTML Load Time
Dimensions - the last of the filters offered by Clicktale are:
Font Height
Width and Height Resolutions
Width and Height of the Web page
As with any quality tool, many features are overkill, but you can create extremely useful combinations, which is the next topic.
