On Pages for brands and products, however, some companies have reported CTR as high as 6.49% for Wall posts. Involver, a social marketing platform, announced in July 2008 that it managed to attain a CTR of 0.7% on Facebook (over 10 times the typical CTR for Facebook ad campaigns) for its first client, Serena Software, managing to convert 1.1 million views into 8000 visitors to their website. A study found that for video advertisements on Facebook, over 40% of users who viewed the videos viewed the entire video, while the industry average was 25% for in-banner video ads.
