Web scraper for Yell
I would focus on the following improvements:


avoid code duplication - for instance, you have the User-Agent string specified twice - extract it as a constant and re-use. GetPageData also has duplicated code
some of your locators are layout-oriented which makes them less reliable and less readable - Bootstrap classes like col-lg-12 or col-md-11 have a layout/design meaning and have a high probability of change. row businessCapsule--title can become businessCapsule--title; col-sm-10 col-md-11 col-lg-12 businessCapsule--address would become businessCapsule--address.
