How to use the spider simulator
Enter a URL and click Crawl page to fetch the raw HTML with Googlebot's or Bingbot's user agent, or paste the page source yourself. The simulator strips scripts, styles and other non-visible code and shows what a crawler reads: the title, meta description, canonical and robots tags, the heading outline, the visible text, every link with its anchor text and rel value, and the alt text of every image.
Why this matters
Search engines rank what their crawlers can read, not what visitors see after everything loads. Content added by slow JavaScript may be missed. Missing alt text costs you image search visibility. Generic anchor text such as "click here" tells search engines nothing about the page it points to. The simulator surfaces these issues in seconds.
What the simulator does not do
It reads the raw HTML and does not run JavaScript. If your site builds its content in the browser with React, Vue or Angular and does not use server-side rendering, you will see a nearly empty page. That is a useful warning: Google renders JavaScript later, but many other search engines and AI crawlers do not.
Frequently asked questions
What is the difference between View Source and Inspect?
View Source shows the HTML the server sends, which is what a crawler downloads first. Inspect shows the page after JavaScript has changed it. For SEO checks, View Source is usually the more important one.
Does Google see exactly this?
Close, but not exactly. Some sites send different HTML to different visitors or block server requests, and Google renders JavaScript in a second pass. Use Search Console URL Inspection to see Google's rendered version of your own pages.
How does Google handle JavaScript content?
Google renders JavaScript, but later than the first crawl. Many smaller search engines and AI crawlers do not render it at all. Keep your key content in the initial HTML for the widest visibility.
What makes good anchor text?
Good anchor text describes the page it links to, for example "marketing ROI calculator". Generic text like "learn more" wastes the link. Aim for short, descriptive anchors across your site.
