of course I can provide a screenshot of the visitor log, but I would prefer not to post it here in public...please post me a line and I would send it by mail...

unfortunately this is by design, since we create one "abandoned cart" per visit and you made 8 visits to the shopping cart page. one solution could be that you only call Piwik when an object was added or removed from the cart, then these "page refresh" would not be counted as extra carts.

thanks for your answer.
I understand.
Keep doing it the way it is you really got only wired numbers...
(It's the same like counting all bots on your website as human visitors...)

so if I understand it right we simply need the (additional) possibility to only count different abandoned cards. This could be done via a comparison of the abandoned card to the abandoned cart of the visit before.
What should be compared is the

• the number and
• the name
  of the articles on the cart,
  or doing it the dirt way (as a first step): only the price sum of theses two cards.

What do you think?

Should I open an extra ticket for that?

or / and / detail

we could distinguish between

1. counting the visitor action "abandoning cart"
   => can be done each visit
2. counting the visitor action "abandoning a new cart"
   => only counts different(new or modified) carts

e.g. in the visor log we need a new symbol to show the difference:

one idea could be simply

for 1. => using the symbol of the supermarket trolley with the red cross and put it in brackets

for 2. => keeping the symbol of the supermarket trolley with the red cross

or doing it the other way around:

we count additionally the number of "the abandoning of each cart"

if this number is 1: it's a new abandoned cart
if this number is >1: it's a re-abandoned cart...

Like returning visitors and new visitors...

what's your opinion?

I re-read your ticket more carefully.
My opinion is that there is a bug in the Magento plugin for Piwik.
On the Basket page, it should not trigger the doEcommerceCartUpdate unless the user actually does an interaction or click to add something to cart or update it.

Here you say that the cart page was simply reloaded. This shouldn't have created a cart entry at all.
Please report this suggestion of change to Magento plugin developer :)

Are you using http://www.statstory.com/piwik-ecommerce-extension-for-magento/ ?
Cheers

thanks for your fast answer/feedback!
yes I'm using this plugin.
I'll post Adrian a message to this ticket...

I have reviewed and it is not a bug. The plugin is working as intended. I will respond to the email HPVD has sent me.
