Ask HN: How can I be more productive by using my browsing-related data?

Given all the data that one can accumulate by browsing the Internet:

  - Favorites
  - Articles saved in Pocket/Evernote
  - Web history
  - Google Web History (search history)
  - Google Ads Preferences
  - Other browsing-related data?

Can I use/analyze these data to be more efficient in my browsing ? i.e: Spending less time on sites whom I don't fave a lot of content.
