This feature is important to web marketers and to a web analytics solution in general. The user should be able to select two periods to compare in the Piwik UI. The graphs, tables, sparklines, texts, would show values for both periods as well as the % of evolution.

Related to comparing segments https://github.com/piwik/piwik/issues/7716 since both would use same mechanism

Hi, I have working on a Piwik for a few weeks and my project needs a period compare mode. Even if this feature is planned after V1, nobody has post on this ticket.
Did anybody work on it? And what is the progress? Could I help to develop the feature since I quickly need it?

@mattab commented on May 29th 2009 Member

nobody is working on it.

The best way if you would like to contribute this back to core, is to post here your specification of what you want to do and how you are planning to do it, and we might be able to review and help you out. This is not a trivial task so it requires careful planning. that would be great new feature though

This feature might be picked up soon as requests are increasing. If you are interested in sponsoring the feature, please contact us at services at piwik.org

Note that the code in the branch cannot be reused, but definitely a good place to look at for ideas on how to implement this the easiest way.

Comparing 2 reports together is useful for dates, but also to compare visitor segments (eg. All visitors VS Visitors coming from Adwords) - see #2135

See this example to integrate "Time comparisons" in a table: http://www.shufflepoint.com/assets/slides/267_prr.png

But a green/red indicator might be as good or better than 2 horizontal lines per row...

This would be used

  • In all tables in the UI when comparing 2 periods
  • In the PDF/Email reports by default (compared to N-1 period)

Is this something we can expect in the future? I really would like to have this feature! I switched from GA to Piwik on a site with millions of visitors a month, I really miss the ability to compare monthly and quarterly reports in a quick and easy way

Yes, we hope to implement this feature in the future. If your company can sponsor this change, it would certainly help make it happen faster :+1: https://piwik.org/development/
