How long does it take after Google connect to show graphs on the Dashboard?

After the connection with Google has been made, it takes up to 24 hours to pull all metric data into the platform displaying it on the Dashboard because the processes are intervallic.

If you adjust the filter to Overall, our system will also display historic data starting 18 months before the actual connection with our tool.

Why is there a difference in Average Rating for the reviews between the platform and Google?

It happens because Google rounds up the average. So, for example, 4,45 turns into 4,5; whereas our platform only shows one decimal of the average, turning 4,45 into 4,4.

What is the difference between Google Queries and Google Impressions?

Queries refer to the (number of) keywords for which someone searches that result in Google showing your site/pages. 

Whereas impressions are the total number of times that your site/pages showed up in Google Search results (not including any paid Google Ads). For example:

If 100 people searched Keyword 1 in Google: then your site showed in Search Engine Result Pages (SERPs) 100 times. Therefore, the total number of impressions is 100.
