This should give 1000 free queries per month for 3 months. After that the cost (February 2017) is 1 cent for every 3 queries. This goes 100% to Microsoft for the use of Bing. Webometric Analyst itself is free to researchers in all respects.
To use the queries, start Webometric Analyst and enter the key in the Startup Wizard.
