Last Wednesday, just before Thanksgiving in the U.S., Google announced that the "new" Google Map was available to be embedded in webpages with no quotas for use. That's the good news. The bad news? In the coming weeks those embeds will include advertisements on the maps.
The embed funcationality is simple enough for "cut and pasters" to use. If you've opted in to the new Google Maps, find the "gear" and choose "embed" from the menu. Select the map size you want to embed and the custom code you'll need to paste into your page will be generated. The embedded maps will have all the customizations logged in visitors see when they visit the Google Maps home page.
As for the ads:
Finally, over the coming weeks we’ll be introducing a new ad experience we think is attractive for users of the new Google Maps embed. This new on-map design will allow relevant local businesses to connect with your users, similar to the ads you currently see in the new Google Maps and Google Maps for Mobile. As part of this release, we’ve also updated the Google Maps/Earth APIs Terms of Service to enable us to launch new APIs with advertising. Existing APIs and new APIs launched without advertising retain the requirement for Google to provide 90 days notice prior to including ads.
