Now updated for Joomla 3.
I added a little inline styling, so it will probably work "out of the box" for none-coders. Some of you might want to remove that and put in in your stylesheet. :)
You can just use it instead of de standard breadcrumbs, all the rest is the same.
If all goes well, this will give a nice category-display in the Google search results.
You must not forget to disable the old breadcrumb module that comes with the jooomla installation, as you won´t need it anymore. Once the new google breadcrumb is working, you will see the orange arrows, and it will look very neat and styled. I am extremely happy that it worked so well and the author promised. Congrats. A must have extension for a succesful improvement of you search engine ratings.
