a plugin which tracks visitor behaviour for defined funnels where a funnel represents a serie of ordered pages a visitor has to browse / complete (for instance a checkout process).

Interesting metrics to know would be
- # of visitors starting the funnel
- continuing the to next step
- the (onsite) page they’re going to when they step out of the funnel
- the page they use to reach the particular funnel step.

Funnel charts UI, see http://peltiertech.com/WordPress/bad-graphics-funnel-chart/

this would be a great addition to piwik. it is one feature, google analytics has, but piwik doesnt. the ability to analyse a funnel-process is very important for a lot of companies. so this feature would make piwik even more attractive to them.

I'm currently attempting to make a plugin to this extent for my own purposes, but just thought I'd share a very simple SQL snippet that could be useful.

SELECT v.location_ip, a.name FROM `piwik_log_action` a, `piwik_log_visit` v, `piwik_log_link_visit_action` l WHERE (v.idvisit = (SELECT idvisit FROM `piwik_log_visit` ORDER BY idvisit DESC LIMIT 1) AND v.idvisit = l.idvisit) AND (l.idaction_url = a.idaction) ORDER BY l.idlink_va

This will retrieve the entire visitor path for the last visitor, this could be ammended to do what you actually want very easily.

I'll update again when I put an interface to what is currently a colletion of SQL snippets.

The bigger challenge of this ticket is to report on each specific subpath from a given page, but efficiently and with large data sets. Rather than path by visitor, we are interested in per page metric.

@anonymous-piwik-user anonymous-piwik-user commented Jul 8, 2010

I understand the bigger scope here. I was providing the snippet as a general POC that the data is available in exisiting databases and can be mined retrospectively (an advantage over existing proprietary solutions), and also to provide a starting point for anyone requiring a small-scale quick solution via their own database.

My current development is able to retrieve statistics for any given path, (since this data is easily mined) on a per-visit/per-page basis but it is not efficient.. yet. I'm currently trying the possibility of archiving data relevant to pre-defined funnel rulesets on *.compute and then only having to retrieve the relatively small set of data for the period since last archive.

(An interesting side development of the way I'm currently looking at accessing data, is that a real-time web map, showing paths to from any given url and its "neighbours" would be a trivial development beyond this. If such a plugin doesnt currently exist.)

I think it's going to be very hard (too hard?) to scale Funnel analytics for Piwik. This would significantly slow down archiving for sure.

However real time visualization of paths on a map, if done well, would certainly be a killer :)

Hi,

As part of my work at http://mysociety.org I've started work on a plugin to produce a funnel report. The code is available here:

http://github.com/mysociety/funnels

It's pretty early days, but it now allows you to define a series of funnel steps associated with a goal, and will track visits to those steps and visualize the results. It's developed against piwik 0.6.4. It takes quite a strict approach to the idea of a funnel at the moment, requiring that steps are visited consecutively in one visit in order for a funnel conversion to be recorded. Any feedback welcome!

@robocoder robocoder commented Sep 17, 2010

crowbot: glad to see someone working on this. Can you post some screenshots?

The strict approach to a funnel is flawed because it's sequential and only represents the percentage not filtered out. (Technically, it's a sieve.) In reality, people may enter at different points along the path, or even skip steps. (This might even be viewed as a subset of click path analysis.)

License. We'll have to provide some license guidance if we include Funnels with the core Piwik distribution, but GNU Affero GPL is ok.

vipsoft: I've uploaded a couple of screenshots as requested. I think you're right, the strict approach definitely has flaws. However, with entry and exit stats you do have some indication of where people are going when they are filtered out, and where they join (or rejoin) the funnel from. I'm going to gather some feedback from our team on whether this interpretation of what a funnel is is useful to them in practice, or if they'd prefer something more fuzzy.

Nice. Have you built any widgets, similar to the bar chart and multi-line (evolution) chart discussed in peltiertech blog? Such might be useful for the dashboard or a funnel overview screen.

That looks really good and interesting :)

Can you please post the current status of the code (after maybe a quick review as per coding standards http://dev.piwik.org/trac/wiki/CodingStandard if you have time). It would be great to look at the code and give some feedback early in the process, so we can hopefuly include this in piwik core in the future? Cheers! great work

I'm going to try and review it this week.

Silly question: does a funnel path have to be associated with a goal?

@robocoder

Contributor

@robocoder robocoder commented Oct 30, 2010

I'll try to find more time for review, but from a cursory examination:

  • this nested loop would concern me re: the impact on tracker performance in recordFunnelSteps:
// pseudo-code
foreach($funnels as $funnel) {
    foreach($steps as $step) {
        if($step['url'] == $actionUrl || $step['name'] == $actionName) {
            SELECT ...
            INSERT ...
        }
    }
}
  • not obvious from the funnel definition page that 'Name' corresponds to action name, and that a "match" for a particular step is either by url or action name; personally, I expected Name to be a free-form description of the step
  • answering my question in comment:18, there should be some help message on the funnel definition page that the goal is implicitly the last step; the dropdown list should exclude manually triggered goals as these have no associated URL
  • API.php: getFunnels, getFunnelsByGoal: should check has view access
  • unit test fails because piwik_funnel table hasn't been created
Exception: Test_Piwik_Funnels -> test_addFunnel -> Unexpected exception of type [Zend_Db_Statement_Exception] with message [SQLSTATE[42S02]: Base table or view not found: 1146 Table 'piwik_tests.piwik_funnel' doesn't exist] in [/path/to/piwik/libs/Zend/Db/Statement/Pdo.php line 234]
  • integration tests fail once plugin is activated (i.e., no expected results)

recordFunnelSteps() might benefit from the tracker cache to replace the call to Funnels_API getFunnels():

  • The tracker cache are files in tmp/cache/tracker to reduce the number of SQL queries by the tracker.
  • In plugins/SitesManager/SitesManager.php, recordWebsiteDataInCache() hooks on "Common.fetchWebsiteAttributes" to cache site data. The funnel steps for each site could also be saved this way.
  • In API.php, any update of the site table is followed by a call to Piwik_Common::regenerateWebsiteCacheAttributes().
  • recordFunnelSteps would call Piwik_Common::getCacheWebsiteAttributes( $idSite ) to access the tracker cache (which may already be loaded at this point), thus avoiding a SELECT during tracking.

@robocoder robocoder commented Nov 3, 2010

I'm falling asleep, but I want to record some thoughts re: the nested foreach loop:

  • if steps are unique, INSERT IGNORE could replace SELECT + INSERT; then inner could "break" after the INSERT
  • alternately, might reduce to a single loop by flipping the funnel data structure around to quickly lookup url/name-to-funnel(s)

crowbot, it would be great to work together to put this plugin into Piwik core.

Do you have a more recent version than the one vipsoft reviewed?

I would like to do a review, but maybe you are making some changes at the moment. Please let me know if you would like a review now or a bit later. Thanks!

Hi matt,

I did start work on replacing the tracker loop with an "INSERT IGNORE" statement - but I haven't really tested it at all - I'll try and get that version checked in in the next week or so - so a bit later would be great!

As far as I'm aware, AGPL3 and GPL3 should be compatible:

Can you tell me where the problem arises? Thanks!

@robocoder robocoder commented Nov 20, 2010

(This'll be terse...I'm afk an using my iphone.)

the licenses are compatible to the extent that we can redistribute gpl and agpl code together, but is problematic if copying/pasting code between the two (eg as in refactoring).

I jotted some notes in #1826 to document the effect of the "network interaction" and "corresponding source" clauses, but will have to revise the text given the expanded scope, ie a request by the js tracking code to the piwik server (and thus, tracker plugins) qualifies as "network interaction"; also "corresponding source" means all modified source, not just those changes upon which a customized Funnels plugin might depend on. This changes the intent behind the decision to use the GPL (instead of AGPL).

For inclusion in core, I would prefer GPLv3 or later, so that there's less licensing confusion.

This is a brain dump, eg new reports / enhancements to this plugin.

  • page views -> unique visits -> user sessions / unique visitors -> ROI / conversion tracking -> click paths / funnels -> propensity to repurchase

Will there be a new "release" of the latest version on
https://github.com/YanK-fr/funnels/releases ?

and maybe you could also push this latest version also to
the non official marketplace
https://github.com/csuenkel/piwik_marketplace
(at this time there seems to be a very old version available there: "0.1 alpha")

=> doing this lots non advanced piwik users would be happy and could use your great plugin - without an installation hurdle...

since the plugin is hosted on github, it only seem to be a very small effort to distribute it in this marketplace: there is an automated process:

oh someone must have already noticed the age of the available version
=> now a newer version (1.11) is available via this marketplace :-)

But there seem to be a problem => how could it be set up? There is a new tab "Funnel" with a text "Funnels Management" - is it a broken link to a config site??

edit: ah ok it should look like
http://issues.piwik.org/attachments/5640/creating_funnel.png

everything below the words "Funnels Management" is missing
see:

and a tiny thing: the funnel tab is shown before the dashboard

Hi,

I don't have installed the last version of the pluggin with Jess's enhancements, but I have a question there :

I have a conversion funnel where all the steps are in fact the same page (//host/souscription?orderid=1234).
Can we define different steps of the tunnel with the same URL ?

Thanks
Florian

@anonymous-piwik-user anonymous-piwik-user commented Sep 20, 2013

Pluggin https://github.com/YanK-fr/funnels installed !

To answer to my question above, even if the different steps of the tunnel use the very same URL, you can use title of page to differentiate them. Well done.

However, I got this warning on each tab with many yellow boxes and long backtraces :

Warning: Invalid argument supplied for foreach() in /var/www/html/piwik/plugins/Funnels/Funnels.php on line 660

There is something to do with the date retrieved in the request.
Indeed, this happen only when the period's end-date is upper than the date where I installed the pluggin.

If somebody can help...

I use Piwik v1.12

Thanks !
Florian

Along with the Piwik 2.0 release and new design for Piwik, we have also launched the official Plugins Marketplace to let any developer share their work to the thousands of Piwik users worldwide.

Maybe you'd like to publish your plugin there?

In any case, keep up the good work and we hope you enjoy Piwik 2!
