Kissmetrics

1. Great tool for collecting the user interaction data towards web based products by defining user events.
2. You can easily track what are the features user liking and buying the product and from where they are abondaning it.
3. It really helps in making decisions towards the products and by performing AB tests over web based products.
4. You can easily acces the analytics data from anywhere by just logging in their site and defining your user funnel.
5. It is also easy to implement over source code of the product just need to include one javascript code and you can fire your events on every user actions.

The interface design of the admin tool is not good.

I think it's fair to say that Kissmetrics alongside Mixpanel are the 2 best tracking and leads analysis tools right now and for us, Kissmetrics won the competition for having a more accurate tracking tools and better pricing for a B2C company.
Generally these apps are made for B2B companies and therefore their pricing won't make sense for B2C since the total number of events they track easily impacts the price.

It takes a long time to implement it correctly especially if you have a complicated website with too many different events and properties.
They do help you to implement it but after it's done, you pretty much need to take care of new events tracking yourself. (Though, their support team still help you if you ask them questions)
There are certain limitations to it too:
- AdWords' dynamic tracking can't be reach by Kissmetrics. So if someone clicks on your AdWords ad, Kissmetrics only tells you it's Google. It can't tell you which ad group or ad it is coming from. Unless of course you deactivate the dynamic tracking and manually put the old UTM trackings for each ad in place.
- If you are doing Facebook Lead Ads, you should know since the lead conversion is happening outside of your main website, you can't store that information with the cookie attached to it to Kissmetrics or any other event tracking software.
- Kissmetrics says they have a good Salesforce integrations but it's not as smooth as you think it is. First of all, it's like an iframe within your SF and second of all, you can't do reporting within Salesforce regarding the Kissmetrics data. Their team says Kissmetrics should be the only place for your BI team to do reporting from.

All these aside, I still believe Kissmetrics is the best event tracking app out there with amazing pricing.

The amount of data it appends and tracks is amazing. We're able to see which prospects are visiting which pages, and the conversion process. This has helped cultivate our marketing messages per audience, as well as track over the course of three years. Historical data has been valuable to compare if our interpretation of the data is accurate. Needless to say, we have been very pleased!

Some of the data isn't easy to summarize but that is really the lease of our concerns.
