I tried to submit the product my site on google merchant but it was not success tell me an easy process for this activity
Google announced the launch of the Google Merchant Center, which allows business owners to submit any product-type items to Google. These product listings can then be used to help shoppers find your site using Google Product Search, Google.com or even integrated with your AdWords campaigns.
you have to sign in to the merchant center and you just have to follow the instructions posted there...I hope you could do it well the next time around...
Can I ask how to register in Google products? Does it require you to make an account or you can use your Google Account (The one you use in Emails, Adsense, Feedburner etc)?
You might want to register a new account at http://base.google.com for the site that you submit to GMC. If it gets disallowed, it won't be attached to your personal Google Account. After you register you must VERIFY and CLAIM the site that you're submitting.
