Crawl Google
Crawling is when Google's automated crawler discovers and requests web pages so they can be analyzed for search.
Key takeaways
- Crawling is the discovery phase of Google Search; without it, pages can't be indexed.
- Use crawlable links, sitemaps, and a clean robots.txt to guide Googlebot.
- Crawl budget is a real concern for sites with thousands of pages.
- Always verify crawl status in Google Search Console.
If Google can't crawl your pages, they may never appear in search results.
Example: How Googlebot Crawls a Blog Post
- You publish a new blog post and add a link to it from your homepage.
- Googlebot visits your homepage (already known) and follows that link.
- It downloads the HTML of the new post, including images and scripts.
- The URL is added to Google's queue for indexing.
- If you later update the post, Googlebot will recrawl it when it next visits your site.
Quick-Start: Make Your Pages Crawlable
- Submit a sitemap via Google Search Console.
- Use crawlable links – standard
<a href="...">tags, not JavaScript-only navigation. - Check robots.txt – ensure it doesn't block important pages.
- Test a URL with the URL Inspection Tool in Search Console.
- Monitor crawl stats in Search Console to spot issues.
- Fix broken links – 404s waste crawl budget.
How to Judge If Your Site Is Crawlable
- All important pages are linked from at least one other page on your site.
- Your sitemap is submitted and error-free.
- robots.txt allows crawling of pages you want indexed.
- No critical content is hidden behind forms or login walls.
- Googlebot can render your pages (check with the URL Inspection Tool).
Common Crawling Mistakes
- Blocking indexable pages in robots.txt – prevents crawling and indexing.
- Assuming a crawled page will rank – crawling is just the first step.
- Using uncrawlable links – e.g., JavaScript events without fallback
<a>tags. - Ignoring crawl budget on large sites – Google may miss important updates.
- Relying on infinite scroll without proper HTML navigation – Googlebot may not load more content.

FAQ
What is the difference between crawling and indexing?
Crawling is when Googlebot downloads a page's content. Indexing is when Google analyzes that content and stores it in its search index. A page can be crawled but not indexed.
How do I check if Google is crawling my site?
Use Google Search Console's URL Inspection Tool to see if a page was crawled and indexed. Also check the Crawl Stats report for overall crawl activity.
Does blocking crawling with robots.txt prevent indexing?
Yes, if Google cannot crawl a page, it cannot index it. However, if other pages link to it, Google may still index it without crawling (rare). Use noindex meta tag for pages you want crawled but not indexed.
What is crawl budget?
Crawl budget is the number of URLs Googlebot will crawl on your site within a given time. It matters for large sites (thousands of pages) to ensure important pages are crawled frequently.
