Does the Google Alerts Method Still Work???

Everyone knows the Google Alerts method, where you create keyword specific alerts so google will notify you every time new content related to that keyword is indexed, you would then comment on as many articles, forums, and blog posts as possible to spread your links. But does this till work? Obviously not for SEO it doesn't but what about general traffic generation???

This method is unaffected by any G updates as per its design. You are posting your comment and link to the freshest targeted sites that are actively commenting on your targeted niche. Why wouldn't it work? This method is perfect for pinpointing and harnessing specific traffic.

Tried this a long time ago and it didnt work well. Your comments will rarely get approved.
