Is your website hacked or slow? 7 warning signs and what to do

Spam redirects, browser warnings and slow pages cost you visitors and rankings. Here is how to spot the problems early.

Is your website hacked or slow? 7 warning signs and what to do

A hacked or slow website quietly costs you money. Visitors leave, Google lowers your rankings and ads send people to a page that doesn’t load. The good news: most problems show clear warning signs.

7 warning signs

  • Visitors are redirected to spam or unknown websites.
  • Google or the browser shows a “this site may harm your computer” warning.
  • You see admin users or files you don’t recognise.
  • Strange pages or keywords appear in Google search results for your site.
  • Your hosting provider suspends the site or reports unusual activity.
  • Pages take more than 3 seconds to load on mobile.
  • Your site fails Google’s Core Web Vitals in Search Console.

What to do if you think you’re hacked

Don’t delete things at random. Take a full backup first, change all passwords, and get a proper malware scan. The infection needs to be removed and the entry point fixed, or it will come back. If Google has flagged the site, a review request is needed once it is clean.

How to make a slow site fast

Most speed problems come from oversized images, too many plugins, heavy page builders and missing caching. Converting images to WebP, adding caching and a CDN, and removing unused scripts often cuts load time by more than half without a redesign.

Prevention

Keep your CMS, themes and plugins updated, use strong passwords, add a firewall and take regular backups. A small monthly maintenance plan is far cheaper than a clean-up.
