Crawler simulator

# Website crawler simulator and bot tester

Last updated September 29, 2026

Simulate a visit from any of 100+ search engine, AI, and social crawlers. Enter a URL, crawl it as the bot, and inspect the status code, HTML, word count, and Open Graph tags it gets.

SIMULATE

## Simulate a crawler visit

Select a crawler and enter any URL on your website to inspect the HTML the bot gets.

How it works

## How to use the crawler simulator

1. Step 1
   ### Enter a URL
   Paste the full URL of any page on your website, such as a product page, a blog post, or the home page.
2. Step 2
   ### Select a crawler
   The tester sends the request with the crawler's user-agent string, so your server answers the way it answers a real crawler visit.
3. Step 3
   ### Run the crawl
   The simulator requests the page as the crawler and follows redirects, the same way the crawler does.
4. Step 4
   ### Inspect the HTML
   Check the status code, redirects, response headers, raw HTML, word count, and Open Graph tags the crawler gets. If your main content is missing from the HTML, the crawler cannot read it.
