💡 Think of it like this: Imagine Google is a postman who can only deliver to certain streets. Web Crawling determines which streets the postman is allowed to visit — and how often.

How Web Crawling Works

Web crawling is the automated process by which search engine bots — Googlebot, Bingbot, and others — systematically browse the internet, following links from page to page to discover and record web content for indexing. Crawling is the first step in the search engine process: before a page can appear in search results, it must first be crawled. This makes crawlability a foundational concern in technical SEO.

Why Web Crawling Matters for SEO

When I conduct technical SEO audits for Nepal-based clients, crawl accessibility is always the first thing I verify. If Googlebot cannot reach your pages, nothing else matters — your content will not rank regardless of how well-written or linked it is. If you’re unsure how Web Crawling is impacting your site, working with an experienced SEO consultant can help you identify the problem and fix it efficiently.

Common Web Crawling Mistakes

You can guide Googlebot’s crawling behaviour using robots.txt directives (which pages to crawl), the crawl rate setting in Google Search Console, and internal linking structure (which pages receive crawl priority through internal PageRank). Blocking important pages in robots.txt is one of the most common and damaging technical SEO mistakes I encounter. Get your crawl configuration checked through a Free SEO Audit.

Do’s and Don’ts: Web Crawling

✅ Do This	❌ Don’t Do This
✅ Submit your sitemap.xml to Google Search Console and keep it clean	❌ Ignore crawl errors — they waste crawl budget on dead pages
✅ Set canonical tags on duplicate and near-duplicate pages	❌ Leave both HTTP and HTTPS versions accessible without redirects
✅ Test your robots.txt before deploying to prevent blocking key pages	❌ Block JavaScript or CSS files in robots.txt — it breaks Google’s rendering
✅ Monitor Core Web Vitals monthly and fix regressions quickly	❌ Ignore page speed issues — slow pages lose rankings and conversions

If you remember one thing — focus on how Web Crawling affects your users first, then optimise for search engines second.
