Google Labs has been a playground for search engine optimizers and marketers
for a long time. Google Labs offer a wide variety of searcher toys that are
not quite ready to be unveiled on the main Google site, and some developments
eventually become a significant part of Google.
Some of the not-quite-ready-for-prime-time players here are:
- Google Transit
- Accessible Search – Web search for the visually Impaired
- Google Extensions for Firefox
- Google Spreadsheets
- Google Notebook
- Google Trends
- Google Related Links
- Google Mars
- Google Page Creator
- Google Dashboard Widgets for Mac
- Google Reader
- Google Web Accelerator
- Google Ride Finder
- Google Suggest
- Froogle Mobile US | Froogle Mobile UK Improved!
- Google Sets
All are fun to play with and each one is worth the one time registration.
