The US and Canada have had access to the new Panama platform for some time and now advertisers in Europe are able to use the new version, just launched this week.
There have been many comments on the new system on both the positive and negative side of things, but hopefully most of the initial issues that plagued US users have been corrected in time for this launch.
When it first launched in North America, Panama caused chaos for some advertisers when the transition saw ad campaigns completely shuffled about. Some key phrases were lost, where others were moved into different groups and some groups disappeared entirely. While not everyone had issues with the account switch, there was plenty to be said in the forums regarding the changeover. (see “Yahoo Panama Pros and Cons, and Part 2“)
Hopefully Europe will see a smoother transition into the new system with the correction of some of the known bugs. Currently, Google has approximately 70-80% market share for search in Europe.
