The ad-blocker, which would be available as a default setting for both mobile and desktop, could spell the end of certain online adverts which many users claim disrupt their browsing experience, the paper said, citing sources familiar with the company.
Targeted adverts are likely to be those featured in a report released last month by the Coalition for Better Ads, a U.S. and European industry group, the Journal suggests. These include six desktop and twelve mobile web ad experiences which it said fell below the threshold of "consumer acceptability," such as pop-ups and auto-playing video ads.
Under one potential iteration of Google's plans, the ban could extend to all advertising that appears on sites with offending ads, rather than just the offending ads specifically.
The reports claimed that the plans could be announced and rolled out in weeks – or withdrawn entirely.
Google refused to confirm the claims, saying "we do not comment on rumor or speculation."
However, the technology company, which is owned by Alphabet Inc., said it had been working to explore new ways of improving the browsing experience for users.
"We've been working closely with the Coalition for Better Ads and industry trades to explore a multitude of ways Google and other members of the Coalition could support the Better Ads Standards," a Google spokesperson told CNBC Thursday.
