    Kohki, as always, great analysis. One question: were these ads all right side bar ads or a combination of right side and newsfeed ads? I have found that newsfeed ads are also quite a different animal in terms of reach/frequency and its impact on CTR/CPC.

    Hi Catherine, great question! The data above is a combination of both. As you say, news feed ads behave very differently from RHS ads, most notably with frequency having a defined ceiling. So the trend for frequency above apply mostly to RHS ads, but the learnings on reach apply to both.
