# How to Monitor and Reduce Crawl Errors: A Complete Guide
#### Introduction

Search engines like Google and Bing use crawlers to scan and index websites, helping your pages appear in search results. When these crawlers cannot access certain pages, the result is known as a crawl error. These errors can negatively impact indexing, page rankings, and overall SEO performance. As websites grow, technical issues such as broken links, misconfigured redirects, or server downtime become more common—making it essential to monitor and fix crawl errors regularly.

If you're looking to boost your site’s visibility and ensure smooth indexing, understanding how to monitor and reduce crawl errors is a critical part of your SEO maintenance strategy.

#### What Is This Topic About?

This guide focuses on how crawl errors occur, how to detect them using tools like Google Search Console, and practical strategies to fix or prevent them. Crawl errors are divided into two main categories:

Site-level errors: Affect the entire website (e.g., DNS issues, server errors, robots.txt blocking).

URL-specific errors: Affect individual pages (e.g., 404 pages, soft 404s, redirect loops).

By identifying and resolving crawl errors early, you support better indexing, user experience, and search engine rankings.
