explicamos esso por causa de a audiência do feed é separada de a audiência do sitio. Quando o tráfico ao feed cresce, tráfico em total cresce. não é evidência que feeds completos possem reduzir o tráfico ao sitio.

in English (if someone wants to do translate better than my poor Portuguese above):

It’s clear that subscribers prefer full feeds. We have cases where publishers publish both partial and full feeds (even with advertising). In every case, the subscribers prefer full feeds with advertising over partial feeds with no advertising. Typically the breakdown is 95% of the people subscribe to the full feed. Most subscribers like to stay in their feed reader whenever they can.

Many publishers are worried about losing traffic to their site when they provide full feeds. The evidence shows however, that most site traffic still comes from search and that feed subscribers are a separate audience. Increasing your feed audience is important, and as it grows, you will find that the total traffic of site + feed traffic is much greater than just the site traffic alone with a partial feed that not many people subscribe to. Many people still click back to the site as well.
