I came across this Chrome browser extension that allows you to see how Facebook collects your data.
It can only use data on what categories Facebook has placed you in (not identifiable information or cookies, for example) but the name of the category, the I.D. number Facebook gives it internally, some other subcategories and your logged reaction to the category.
There are so many questions, rumors and concerns about social media and the Internet concerning privacy and data collection that this seems very relevant. I know that amongst my own friends and students there is a lack of knowledge about what is collected and how it is collected when you’re online, but there are a lot of negative feelings about it.
Most people know that sites want to determine your ad preferences and use data and tracking to figure out which ads might be relevant and useful to you. They don’t do it to be nice to you – although if I have to see an ad I would rather it have some relevance – but because advertisers want to know their ads are getting to the correct people.
Your Facebook profile information and interactions with friend and businesses influences the ads you see. It is not so different from targeting ads from before the Internet Age. Demographic information—such as age, gender and location have always been important. But we voluntarily give so much more information (even if unconsciously) by our thousands of clicks and activities online that targeting is much more refined.
When you use the “What Facebook Thinks You Like” app offered by propublicasocial, you’ll see how your interests in people, travel, news etc. help determine the ads you will see.
