Google Maps added a quick embed feature which lets you quickly add any map to your web site. Prior to this, you needed to have a Google Maps API key, which is fine if you are developing a larger application, but a pain if you just want to make a blog post with embedded directions.

To use the feature, you just click the “Link to this page” link at the top right of any map in the Google Maps interface. There’s a quick snippet of 425×350 iframe embed code that you can then copy, or you can choose to customize the layout. The latter lets you select the target size and additionally allows you to tweak the map view to zoom or center on the area of interest.
