What is how to tell what platform a website is built on?

1. Check the URL structure: Many website platforms use unique URL structures for their pages. For example, websites built on WordPress tend to have URLs that end in "/page-title" or "/post-name."

2. Inspect the page source code: You can view the page source code of a website by right-clicking on the webpage and selecting "View Page Source." Look for specific platform-related code, such as WordPress themes or plugins.

3. Use online tools: There are several online tools available that can help you determine the platform a website is built on. Examples include BuiltWith, WPThemeDetector, and WhatCMS.

4. Look for telltale signs: Each website platform has its own unique features and characteristics. For example, websites built on WordPress often have a "Powered by WordPress" footer, websites built on Wix have URLs that contain "/site/," and websites built on Shopify have checkout pages with a specific structure.

5. Visit the website's robots.txt file: Some websites include information about the platform they are built on in their robots.txt file. You can view this file by visiting the website's URL and adding "/robots.txt" at the end.
