Thank you all for your support!

This is the first post of a new series all about "Using Piwik Effectively" and in a live environment.  Designed to help both businessman & hobbyist make the most out of Piwik.

Analytics Set Free - No More Constraints

There is no doubt that we are now in a world where digital data, bits & bytes, 1's & 0's all have a value, and a very significant value at that.  Just look at Google as a classical example of how valuable the digital world has now become.

Without data Google would have nothing to work with and I would be out of a job.

Previously when using say radio advertising or TV slots it has been a very hit and miss sort of game.  You don’t have an in-depth view into EXACTLY what it is that your viewer is looking for, so you would have to profile a demographic and then hope your offer or advert was appealing enough to spark interest.

Now bring it into today's digital world and you can track almost everything.

This puts an immense power in the beholder of the most data as not only would you know how people are using the internet, but you would also have so many small bits of data around each visitor that you are now able to start to profile your visitor or future customer.

So how on earth does this relate to Piwik?

Well…..

Let’s suppose you are using another of the many large third party tracking programs, who do you think owns all of that valuable data that is being tracked from your site?

It's certainly not you.  Sure you may be able to analyze that data and see some nice pretty reports, but at the end of the day that data does not belong to you and you are confined within the restraints that the third-party solution would put on you.

Now just imagine for a moment that you had access to a completely free piece of software that let you take control over your sites and the data collected from them….

Welcome To Piwik

Piwik is the ONLY software of its kind around that gives you total control over everything and the ability to expand and use your own data beyond your wildest dreams…

So on with the seven reasons.

#1 You Own The Data

This is one of the biggest reasons you would want to move to Piwik (this combined with #2 & 3) below and it becomes a knockout.

#2 Fully Expandable Feature Set Just Like Wordpress

We all know that wordpress out of the box is nothing special.  It’s just another blog solution, until you start adding in plugins to extend functionality.  You could almost say the same about the Iphone, it’s the applications that make it.

Well this is one feature that makes Piwik REALLY shine out, the developers when setting out to build the ultimate free open source tracking system developed it with expansion in mind and built into it a plugin system that lets you just tap on entire new modules of function with simply a few mouse clicks.

This is HUGE when combined with #1 & #3

#3 API Developer Access

Complete API access is something that has been built into Piwik right from the very core.  This means that you can access any data from within the current functions of Piwik and easily import it into your own application to even further enhance your experience.

If you need to access more data or access it differently then you can easily create a new plugin from #2 to handle and work with that data, this will then make it available as an API.

In case the alarm bells have not gone off in your head just yet let me put this in another way.

Let’s say that you wanted to be able to see the top 3 pages viewed by visitors by country.  No worries all you need to do is create a new plugin that adds that functionality in and hey presto you can now do this.  But taking this even further.

With the combination of points #1, #2 & #3 you can now create your own custom applications (adobe air, .NET, php or any other language you like) that can import any of this data and then use it however it likes.
Imagine if you could have a desktop application that when you opened it could show you the following at a glance.

1.    How much you had made today in sales & from what products.
2.    A comparison of today vs the same day last month.
3.    The weekly average of your sales also in comparison to last week.
4.    Your top performing traffic sources by ROI (because you custom created a plugin that let you set a specific traffic referrer by advertising budget with them)
5.    The top pages that converted into a sale for you

This is just a simple example of how you now have an ROI & Commerce relevant application based entirely off your Piwik data.

Amazing right?

(Feel free to get in touch with me about developing custom Adobe Air applications I am looking for someone to give us a hand).

#4 Real Time Tracking

As its on your own server you can refresh stats as much as you want and get up to the second traffic stats.

#5 Total Privacy

Do you really know what all of these third party services are doing with your data?  What if it were in any way able to help your competitor gain an advantage over you?

Not anymore you have Piwik

#6 It’s Free

Hey free is always good, just this good has sugar coated on top.  Of course it is important to note that there are server costs or hosting costs though if you are running a few websites this is already covered.

#7 It Will Make You More Money

If data is valuable, and you now own all of your data, by default you have increased your wealth digitally.  You can now very easily run custom search queries or strings across all of your sites, across all converted goals or products and find trends that you may never have even noticed.

Piwik being only 1 year old and already covering as much ground as it does really sets the future for what you can expect from Piwik.

As you can see Piwik really kicks butt and is a serious contender to the analytics game, one that in my opinion gives you more power than any of them.

I know it is giving us an edge over our competition by letting us develop custom applications and plugins that provide data in way that has never before been achieved.

Over the coming weeks I will be posting more Piwik guides on how you can leverage Piwik even further in a real environment with real sales coming through the door, these will be live case studies on sites making well over 7 figures.

Please if you have any queries or questions about topics you would like covered in this  Using Piwik Effectively, Marketing Series feel free to post them as a comment and I will take note of them all.

Cheers

Inspired by Remy Damour's code contribution, planning and redevelopment of piwik.js began over 9 months ago. Over this period, we continued to maintain the legacy piwik.js while developing this new and improved version. We looked at the APIs of the "Big 3". We heard your complaints. We read your suggestions. We tackled your support requests. And after many code reviews and test cycles, we believe it's time to unleash the code.

On behalf of the Piwik community, I'd like to thank everyone who submitted bug reports, suggestions, and input that drove this rewrite.

Highlights

The new piwik.js is:

• Object-oriented.
  Multiple trackers on the same web page is now possible. And with the exception of legacy support, the code lives entirely in the Piwik namespace.
• Backwards compatible.
  You don't have to update the tracking code on your pages. Note: we have deprecated piwik_track(), piwik_log(), and global variables for configuration but backward compatibility will always remain.
• XHTML-friendly.
  The code no longer modifies the DOM. Specifically, the calls to document.write() — to attach the transparent 1×1 web bug image or to detect plugins in Internet Explorer — are history.
• Less restrictive.
  The code is more forgiving about where you insert the new tracking code in your pages. Also, custom data is now JSON stringified and no longer limited to a flat structure.
• Industry-conforming.
  The code now tracks the click event instead of mousedown.
• More customizable.
  Check out the API. For example, you can now define your own CSS classes for piwik_ignore, piwik_download, and piwik_link.
• Heavily tested.
  We added automated unit tests via QUnit. The code also passes JSLint and (Microsoft's) JavaScript Leak Detector.

Documentation

You can find the updated documentation for the revamped JavaScript tracking API here:

As always, we would appreciate your feedback. Thank you for using, supporting, and promoting Piwik.

Piwik is highly extensible thanks to the Plugins Framework and the web service API. Custom Plugins can be developed to meet your business needs, add a new feature, or modify an existing functionnality. Piwik can easily be rebranded and offered as a white label web analytics solution to your customers or community users.

We have received many requests for custom paid plugins development from community users, companies, SEO experts. The Piwik team would redirect these demands to community members that we knew were available and knowledgeable about Piwik; to simplify this process and make it easier to find the right person to help you, we have created the Piwik Consultant directory. The Piwik Consultants listed are approved Piwik developers: their previous work on Piwik has been reviewed by the Piwik team and followed our quality guidelines and coding standards.

How can I become a Piwik Consultant?
We would like to get more qualified developers listed on the page. Please see the FAQ How can I become an official Piwik Consultant? for more information about what is required to be listed on the consulting page.

We hope that the Piwik Consulting program will be useful for users seeking quality Piwik related work. Piwik does not receive money from this program, but we encourage that the work is made open source, so that this benefits the whole Piwik community. We already had one plugin built thanks to this program, and we hope to see many more. Good luck to our consultants!

What is an "API" in Piwik and how to use it?

In Piwik, every plugin can expose its own API. Creating an API in a Piwik plugin is as easy as creating a class in a file called API.php; see example of the UserCountry/API.php API.

This class is then automatically loaded in Piwik and the public methods of the class are automatically available to call as a REST web service. For example, to call the method

public function getCountry( $idSite, $period, $date )

You can simply call:

index.php?module=API&method=UserCountry.getCountry&idSite=1&period=day&date=yesterday&format=xml&token_auth=X

You can see that the parameters idSite, date and period are automatically mapped from the URL to the original php function. This is where the magic happens, using the PHP Reflection API.

The page piwik/index.php?module=API&action=listAllAPI, available from the "API" link in the top bar of the Piwik user interface, will load all plugins API files, and automatically generate the "documentation", with example links to the calls.

How is this automatic REST API implemented in PHP5?

I have published a quick presentation about the concept behind the implementation of this API code. Here is the embed presentation:

You can also see the presentation on slideshare: "Easy rest service using PHP reflection api - on slideshare"

All the code used for this API functionnality is located in piwik/core/API/* ; you can browse this code online in the Piwik code browser. Feel free to reuse this code in your project, and submit any patch that you may have to the Piwik team.

If you're interested by this topic, see also the blog post: How to design an API?

Let us know your feedback or questions.

You can say that I am a bit of an analytics freak since my background is financial and I typically work with analytical data and with spreadsheets. Now as a part-time webmaster, I find that using analytics is pretty important to optimize a site. I was intrigued with Piwik when it first arrived - especially as an alternative to Google Analytics.

When I was playing with Piwik on my site, I was looking to show my stats without having to give anonymous users view access to my stats. At the moment, it is only possible to show PiWik widgets publicly only if you give anonymous users view access. So I was curious to see if I could leverage Google Spreadsheets and the Piwik API to publish data and charts from Google Spreadsheets.

I have say that with the PiWik API is was really easy to use within Google Spreadsheets. Since Spreadsheets has the handy importXML function, it was a nice fit since the PiWik API can product its data in XML. It is also easy to change the Piwik API using normal spreadsheets functions. The result is the following Google Spreadsheet which has 3 pages to show you an example:

http://spreadsheets.google.com/ccc?key=pxxUvud3iB_ZgeTOMg64jdw#

• Page 1 – Setup / Configuration

• Page 2 – Dashboard Example: This example shows how to make dynamic reports since you can change the number of “Top Website Referrers” or “Top Keywords”.

• Page 3 – Chart Example: In this example, the chart can be published anywhere as a simple image. No need for flash like Piwik widgets.

The above spreadsheet is in view only mode so you’ll need a Google account to make a copy of the spreadsheet to play around with it. Also, I have noticed a few times that Google may at times not get the XML data – just be patient. When you look at the spreadsheet, I have put in a simple setup page so you can change the reports for your site on Piwik. Just enter in your url where Piwik is installed, siteid and token_auth (that you can find on the API page in Piwik) and the reports will refresh automatically with your data!

The nice aspect of this is if you are using Piwik for commercial customers is that you can create all kinds of dynamic reports which operate in real time. I think the possibilities are pretty endless now. The only downside is the potentially performance impact of using many Piwik API calls.

Happy Reporting & Analysis!
