Ad-blockers have become a must-have for anyone who spends time online, and it makes sense. There’s nothing more annoying than an obnoxiously loud video that drops in front of you as you’re about to read an article. Ad blockers are free, easy to install, and they make browsing faster. According to a report from PageFair and Adobe, ad-block usage in the U.S. grew by 48 percent in 2015 and increased to 45 million monthly active users during the second quarter of 2015.

But what’s good for some, isn’t for others. Advertisers lost an estimated $21.8 billion, the report notes. And ad-blocking has not only been a problem for the advertising and publishing industry, it’s presented a real problem to small business owners. With fewer dollars to spend and confusion with the myriad of digital advertising choices, many of us are concerned that ad-blocking software inhibits our marketing reach.

Not on Facebook.

This week, the social media giant said it will still show ads even when there’s an ad blocker present. In a blog post the company said that it put more tools in place for users who want to block certain ads. But even as more controls are given to its users, the company said it will “also begin showing ads on Facebook desktop for people who currently use ad blocking software.”  Translation: If you’ve got an ad-blocker, it’s not going to work on Facebook.

Of course, Facebook is trying its best to balance user experience with its own hunger for advertising revenue. But this is also an opportunity for advertisers, particularly small businesses. In its blog post, Facebook says that “the right kind of ad, ones that are relevant and well-made” can be useful and help us “find new products and services and introducing us to new experiences.”

Facebook is the most popular social media for small businesses like mine. We have meager budgets. We want our ads to be seen by as many people as possible and not blocked.  o where are we going to get the most bang for our advertising dollar?
