I noticed that the "show map of" link has recently popped up in the Google listings of some of my projects.
I searched on the net to understand the mechanics behind this feature, but I couldn't find any clear explanation.
So far, just two explanations came to my mind, please correct me if I'm wrong:
- Google uses the addresses I set up in the Google Maps modules and concatenates them with the rest of the data of the page content.
- Google extracts the addresses (some project have addresses in the page content), from the content of the pages and associates them with the rest of the data.
I would like to know how Google extract the address information from my pages to eventually "control" the use of my data. Also, I'd like to switch to an alternative of Google Map like OSM, and I want know if that will impact the "Show map of" feature.
