Unjustified ratings and reviews in google SERP?

[Darioz]

I was checking Google US for some search term my company is interested for and found a thing I cannot explain well.

The site Tradecarview is shown with a rating of 4.4 stars from 4209 reviews. (Please see attached image).The same rating is shown on their homepage, but I could not find much more details. (By the way: Tradecarview is a sort of directory for used car dealers to post their vehicles, something similar to Ebay or Yahoo motors.)

The question is simple: is Google trusting the ratings given directly on the website?

Maybe just summarizing the ratings shown here? http://www.tradecarview.com/pr/providerlist.aspx?pn=0&st=7

Or are there other sources I couldn't find that Google used to specify the rating?

What do you think?

Thank you in advance for your answers,

Dario

Hello, thank you, I understand.

In this case "seller reviews link" is not available, so it is not possible to directly check the websites the ratings come from. (see them image of the SERP I have attached).

Also the second funny thing, is that the rating and the number of reviews shown by Google is basically the same of the one declared by the website itself in their top page.

It seems almost that Google is taking the rating directly from the site itself.

What do you think?

Google looks at a range of review sites, lets say 5 and works out a star rating from the feedback given.

I know for a fact from speaking to my Google account manager if the star rating worked out is 4+ stars then you have an option to turn it on for Adwords Ads.

So the answer to your question is no, they take the reviews from a wide range of review sites and use that data.

If you click on seller reviews link, it should take you to another Google page which shows the reviews, you can then click a link and it will take you to a review site showing that review.
