...Do you agree that sales might be lost due to the way Google is set up?
No. I believe that lost customers occur long before the payment page ever comes up. What I mean is...
When I arrive at an online store, I make some initial decisions about whether I want to shop there based on professionalism and organization of the store itself. If the store has professionally made graphics and template, well written privacy and about us pages, fair shipping and return policies, and no broken links or revolving doors to nowhere, then they are okay...so far. I don't like to see banner ads and confusing specials all over a store either.
Then I size up the selection and price offerings of their merchandise. If the descriptions and pictures are crystal clear and informative, then I feel safer. If anything did not scare me away by now I am feeling more confident. If they have exactly what I was looking for, I may take the leap.
By the time I arrive at the payment page, I have already made the decision to buy and my credit card is out of my wallet. As long as the payment methods are at least ones that I have heard good things about, I would give them a try. The fact that I get sent to Google to log in actually makes me feel safer because they are a household name all over the world.
You wouldn't have lost MY sale because of GCO.
