You need a minimum screen resolution of about 700 pixels width to see our exercises. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.
Create a new Power BI report. Load data from the Excel workbook in the above folder to get:
The initial list of websites (we have much to do).
Make the first row the header row and rename and remove columns to get:
Better - now the fun begins!
Add in a column to number each row, as shown here, and rename the resulting column to Ranking:
This option effectively numbers each row.
Use splitting columns to derive the current Alexa rank, keeping the number but losing the bit in brackets after it:
Alexa is an online tool to show how popular websites are (it's by no means 100% reliable). Although the early Alexa numbers are the same as those for the website's ranking, you'll see there are big differences towards the bottom of the list.
Load this data back into Power BI, and use it to create a chart something like this:
This chart shows how many domains there are for each country and type.
Save this report as Google rules, then close it down.
