"'I suspect we'll see the industry adjust to try to circumvent ad-blocking technology," said Andrew Frank, analyst at Gartner. It'll be a game of cat and mouse.'
There are several things that advertisers can do to counteract the effects of ad blockers. Frank said there are ways to hide the source of an ad, circumventing blacklists. Publishers can also embed the content on their servers, rather than hosting it elsewhere. The way most ad blockers work is through a blacklist system. Advertisements are typically embedded into a publisher's webpage.
Ad blockers usually run as browser extensions, and tell the browser to skip loading content from sites it identifies as coming from servers that supply advertisements. Ads usually pay out either for every thousand impressions, where a publisher gets paid however many times the advertisement is seen, or for every time a user clicks on an ad.
If an ad is never seen, it never gets viewed or clicked."

"The next version of iOS comes with a major new feature called ‘content blockers’ which will allow users to install apps that block trackers, advertisements and other unwanted content for the first time."

"Much has been written about the impending threat of ad blocking on iOS — it’s the first time blocking mobile advertisements en masse will be possible and publishers may face an existential threat to their revenue streams.
Content blockers on iOS are a new type of app that’s able to block incoming content before it’s loaded by the system — it provides a list of sites and scripts to the operating system for blocking. Instead of requiring the browser to process what to block as the page loads, it’s performed on a system level before the page loads which increases speed significantly."
