If Google detects your website has been hacked, it won’t whisper – it shouts with big, scary warnings. From red screens to alarming browser alerts and unsettling messages in search results, these alerts are designed to protect users—and put serious pressure on you to fix your site fast.
Whether you’re a small business owner or run a large e-commerce store, these warnings can cripple your traffic, destroy your SEO rankings, and damage your reputation. A hacked website isn’t just a technical issue—it’s a business emergency that demands immediate action.
