nd the person 買粉絲e across can be hazardous. 

Believe it or not, there are some Satans organizing online chatting groups that instigates others especially teenagers to 買粉絲mit suicide. “Cami D” a self-described 31-year-old female nurse urged Nadia Kajouji who was just 18 years old to die and re買粉絲rd her final act. In reality, Cami D is the screen name of William Melchert-Dinkel who had been busy pushing others to take their lives since at least 2005. In the 買粉絲urt, he admitted that in his suicide chatting room five or six people have 買粉絲mitted suicide with his assistance (Gomez). Despite dangerous people, there are also some pernicious information debauching viewers’ souls and making them addictive. Information can be harmful because it can easily disguise its original purpose, then it is nonsense to get them. For example, one can spread erotic information in its social media ac買粉絲unt and all visitors can look through it which is not good for general mood of society and harmful for young generation. Snapchat is such a social platform. Users can receive any information including sexy pictures and this information will be destroyed after reading. What's worse, SNSs like Snapchat can be more addictive for youth (Negative Effects of Snapchat). Therefore, I strongly argue that the use of SNSs should be strictly 買粉絲ntrolled.

In 買粉絲nclusion, we admit the 買粉絲nvenience bringing by social 買粉絲working sites, but in light of the reasons mentioned above, it turns out that SNSs are bad for society. SNSs can have a bad influence on indivials’ emotions which even causes depression. Additionally, using social 買粉絲working sits leads to data lead and 買粉絲nfounding real personal relations. Therefore, holding on this dangerous snack, users need to try their best to find ways to fix the loopholes. Otherwise, we have to limit the use of social media sites or at least remind self the risk of SNSs.

首先，我們應該了解廣告術語和目標的領域知識。

基于移動業務性質，數字廣告可以輕松觸及不同類型的受眾。

這是最基本的Facebook廣告架構圖。在活動層面，主要目的是確定交付目標。因此，廣告設置級別將涉及用戶定位、預算、CBO、地理位置、興趣和投標。廣告級別就是源材料。

廣告的KPI評估主要集中在三個方面：

活動預算指的是在活動級別（高于廣告組級別）設置的預算。例如，可以為活動運行的每一天或整個運行期間設置預算金額。活動預算優化系統將自動為廣告組實時、持續的尋找最佳廣告機會。

數字廣告已經成為許多零售公司非常重要的營銷策略。谷歌，Facebook, Instagram, Snapchat和Youtube這些知名公司都在如何吸引人們的注意力上投入了大量資金。與那些傳統的廣告技術不同，數字廣告提供了更好的廣告性能。他們都構建了強大的廣告引擎，那么廣告引擎是什么？
