Hi, I have an Annotated Bibliography. My professor asked me to get 20 sources about ( How does social media affect business?! )

The annotated bibliography should be informative and descriptive and it should not exceed 70 words for each source. Basically, you have to read the abstract of each source and paraphrase the main points ( what the authors or researchers discussed, examined,etc..) Then you should add 1-2 sentences how the source is relevant or useful for my topic?

for sure, APA citation should be added before the paragraph of each source.
