If I am not wrong, I feel I have read at your site that our reseller ratings will automatically be linked or pulled in Google shopping account. And will show against our store.
Please help me providing the procedure linking it,
Google will add them automatically. I did not have to contact google or anything on my part. I suppose that Google added them when they matched my store listed on resellerratings and my products listed through Google Base. Also, it did take a while for the ratings to be linked to Google.
I would say at least 4-6 months after my first rating... it was quite a while unfortunately. Hopefully they have improved this process to where it doesn't take as long.
It is very inconsistent the way the ratings appear. In theory they should appear within 24 hours, however I had experience where they would appear and then the next day they would be gone.
It may be a work in progress; as everything is with google.
