How to Determine if a Website Was Created Using WordPress?

So, how to identify if a website is built with WordPress? This popular platform powers millions of sites, but identifying one can be tricky. But don’t worry; there are detective methods to unveil the secrets behind a website’s creation. Let’s explore some ways to sniff out if WordPress is the mastermind behind the scenes!

Try adding “/wp-admin” to the website’s URL. If it leads to a login page (though it might be disguised for security reasons), it strongly indicates that WordPress was used to power that website.

Right-click and view the page source. Search for keywords like “WordPress” or “wp-content” in the code. These suggest the site uses WordPress.

Several online services can identify website technologies. Search for “WordPress website detection tools” to find these. They analyze the website’s code and provide details about its platform and potentially used plugins.
