Online advertising is a common phenomenon on the Internet, as it is the way many companies generate revenue. However, from the user’s perspective, these ads can seem strange, annoying, or even disturbing, especially when the same ad seems to “follow” the user. For example, you might visit Nike’s website, then open an article on another company’s website and see an ad for the shoes you just viewed.

While these ads can help remind you of products you might want to buy, they often get in the way of content you want to see and can slow down web page load times.

Online advertising is necessary to support websites and cover costs such as web hosting, compensation for writers and developers, and other expenses. However, many people find online ads intrusive and annoying and prefer to turn them off. This is supported by several studies that show the negative attitude of people towards online advertising.

It’s clear that most people who use the web don’t care about ads on their websites, blogs, video sites, or social networks. But as people have become accustomed to online ads, advertisers have become more creative with their marketing tactics, creating something called behavioral retargeting, also known as ad remarketing.
