Google, Bing, and Yahoo! are already using Schema.org markup through which they understand the data on page. So, you can manually add this data and tell Google to show rich snippets like star ratings in SERP(Search Engine Result Page). This data is being added manually, so, you can indeed add any value you want. A 5 star rating with few thousand reviews..haha noone is stopping you do that.

But please note, these are blackhat tricks and google will certainly find it out. In such a case, it is advised to install Rating widget and tell google that rating is coming genuinely. Better, right?
Here, we have used blogger as the trial because it’s free and easy to use. The results appear depending on how soon google crawls your web page. You can speed up this process like hundred times faster by using fetch and submit too in search console or simply, google webmasters tool. Don’t temme you don’t know yet what it is.
