Behavioral advertising. If you have visited a website in the last decade, or use any social media platforms, then you've been subjected to behavioral advertising. The old saying goes, if an online service is free, then that means *you* are the commodity.
We've all seen examples of this - visit Amazon, and see a list of recommended products based on your shopping or even browsing history. The same applies to Facebook (friend recommendations, games and apps, linked ads related to commentary you may be making on the site); LinkedIn (based on your social activity), Twitter (based on your connections, tweet activity, and topic searches).
All in all, this is not such a bad thing - some people may find it nice that the product they were thinking of just happened to be recommended to them on their next visit to that shopping website. But in some cases, this type of advertising can not only be annoying and spammy, but downright aggravating.
How to manage it, then? Here are my tips:
If you want to have some control over your Facebook feed, install Social Fixer
To eliminate pop-up ads, auto-play ads, sidebar ads, etc - install AdBlockPlus
Check and update your permissions on most of your platforms.
