Google: End of the Online Advertising Bubble
"Facebook on the other hand, has a better control of who is actually seeing its ads, and will benefit from the turmoil by gaining market share."Did they pay you to write this?Google ads in search will always be valuable because you can advertise nail varnish to people who have just searched for "buy nail varnish".This is also about the millionth post I've read which assumes that companies simply throw money at advertising and don't run any statistics of their own. Simply, if you spend a lot on an ad campaign for a product and your sales don't go up, you notice that and rethink your next campaign. CPM and all that are at best proxy metrics for the thing you really care about, "are our profits/sales up".
