Google makes this easy. This is best done after you have established your business in Google Places. Simply search for your business on Google Maps and select directions option. After you locate it you will see a Link icon (chain links), chick on the link icon. Follow the “Customize and preview embedded map” link, now select the size you would like, then copy and paste the code provided to your company’s directions pages.
Adding a text description with landmarks should also be included on the page, along with any parking information. Recommend a parking lot if you do not have on-site parking.
