A search engine spider (also known as a web crawler or bot) is a program used by search engines like Google or Bing to crawl, index, and rank web pages. These bots do not see your site like a human — they read the raw HTML code, links, metadata, and content structure.
The Search Engine Spider Simulator by seochecker.tools helps you visualize how these bots view your website, allowing you to identify SEO issues, hidden or inaccessible content, and blocked resources.
Preview how bots interpret your web page
Find inaccessible or hidden content
Verify if meta tags, alt tags, and keywords are properly used
Detect broken internal links and redirect chains
Analyze crawlable vs non-crawlable elements
Optimize crawl paths for search engine efficiency
By understanding the spider’s perspective, you can better optimize your on-page SEO and ensure all important content is indexable.
Shows pure HTML content as bots see it
Highlights visible vs hidden content
Lists all internal and external links
Displays metadata (title, description, keywords, canonical)
Detects redirect chains and blocked resources
No login required, fast and accurate
Q1. How is this different from viewing my page source?
Your browser may render content dynamically via JavaScript. Spiders often do not execute JS. This simulator shows the static HTML output that bots actually crawl.
Q2. Can I use this tool to test JavaScript-based websites?
Yes, but keep in mind that some spiders may not render JS content. If your core content loads via JS, it may be invisible to bots unless server-side rendering or proper SEO techniques are used.
Q3. Why is some content missing in the spider view?
That means your important content may be blocked via robots.txt, noindex, or loaded via scripts that bots can't process.
Q4. Does this tool show metadata?
Yes, it extracts meta title, description, keywords, canonical tags, and header tags for bot-view comparison.
Q5. Can I improve SEO by simulating spider views?
Absolutely. This is one of the best ways to catch content visibility issues and optimize how search engines crawl your site.
Check if search engines can crawl your site properly
Validate SEO metadata, internal links, and headings
Test if dynamic content is visible to bots
Perform pre-launch technical SEO audits
Troubleshoot pages that aren't indexing properly
