Most website owners and bloggers depend on banner advertisements as one of their revenue streams. Banner ads come in a variety of styles, which fit well with websites that come with a mobile version. The iOS & Safari has been contributing quite a high percentage of bringing traffic and ad incomes to the mobile sites. The latest report shows that iOS is the major revenue contributor although it brings less traffic than the Android counterpart. But this will no longer be true when iOS 9 arrives on the iOS devices.
Of course, Content Blocker only functions when it’s enabled by the users. The beta version of the iOS 9 hasn’t yet got this function but NewMobileLife has got a version from one of the developers, Crystal, which shows a screenshot as above on how Content Blocker (just below the Block Pop-ups) can be enabled and added with a list of disallowed sites; by going to the Safari’s Settings on the iOS 9.
