Part of the technology behind search engines and search engine optimization consists of the processes of crawling and indexing. But what is crawling and indexing? These are processes that search engines like Google use to discover and organize web pages. They are important to understand for anyone who wants to master SEO, and often when you need to solve an SEO problem too. It’s essential to ensure your site is being crawled and indexed if you want its pages to be discoverable through search engines.<\/span><\/p>\n

This guide will take you through the ins and outs of SEO <\/span>crawling and indexing<\/span><\/a> to understand the science behind it. It will help you get a grip on some of the technical principles of SEO and the steps you can take to ensure your site is being crawled and indexed properly.<\/span><\/p>\n

Dive Into Web Crawling<\/span><\/h2>\n

Crawling is the first part of the process of crawling and indexing. Pages can’t be indexed until they’re crawled. So what is it, what is a crawler, and how do they work?<\/span><\/p>\n

What is crawling and what’s it for?<\/b><\/h3>\n

Crawling is the way search engines find and index URLs on the internet. Crawlers are tasked with discovering as many pages as possible by regularly checking for new content. They will crawl both URLs they’re already aware of and new ones that haven’t been crawled before. Once a URL has been crawled to discover information about it, that information is passed on to be indexed.<\/span><\/p>\n

How crawlers discover new pages<\/b><\/h3>\n

But what exactly does a crawler do to find out this information? A crawler (also known as a spider, robot, and several other names) works by moving from link to link. It finds out information about each URL and how they’re connected, then brings that information back to the search engine’s servers.<\/span><\/p>\n

There are several ways search engines begin to find these pages. Google has an initial list of websites called a <\/span>seed list<\/span><\/a> that it views as trustworthy and that link out to lots of other sites. Backlinks are followed from site to site. Additionally, sites that have been previously crawled will be crawled again, and crawlers will also look at sitemaps that have been submitted by the owner or administrator of a website. Users can manually submit sitemaps and request crawling and indexing for individual pages.<\/span><\/p>\n

Challenges faced by crawlers<\/b><\/h3>\n

Crawlers are clever but they can run into <\/span>problems<\/span><\/a> too. Sometimes they may be unable to crawl content or might be confused by what they find.<\/span><\/p>\n

One of the issues a crawler can run into is duplicate content. When a site has duplicate content, it can reduce how often the site is crawled. Search engines like Google don’t approve of duplicate content, so if it’s found it could have a negative impact on SEO.<\/span><\/p>\n

Infinite pages present another problem for crawlers. When a website is too large, it can make it extremely difficult for a crawler to discover all of the pages. It might avoid crawling the whole site for fear of overwhelming it. Too many pages can also slow a crawler down. What’s more, a sprawling site may have bad architecture, making it difficult for crawlers to find pages.<\/span><\/p>\n

Restricted access will also affect crawling. This can include pages being blocked in the site’s <\/span>robot.txt file<\/span><\/a>, nofollow links, or noindex tags. These things tell crawlers not to look at certain URLs, meaning they won’t be crawled or indexed.<\/span><\/p>\n

How to optimize for efficient crawling<\/b><\/h3>\n

Site owners can take steps to optimize for efficient crawling, helping search engines discover their pages.<\/span><\/p>\n

The first step is to check the site’s robots.txt file. The robots.txt file tells search engines which parts of the site should and shouldn’t be crawled. Understanding it and how it works can help you take control of crawling. You can use robots.txt to block some pages from being crawled, such as duplicate content or non-public pages.<\/span><\/p>\n

Using proper URL structures helps to ensure your site is crawled sufficiently too. The URL structure is the different parts that make up the URL. When creating URLs for different pages, they should help to give your site clear structure and organization.<\/span><\/p>\n

Finally, make sure you keep an updated sitemap. Your sitemap tells Google about the structure of your site and which pages are on it. Ensuring search engines have an up-to-date sitemap for your website will mean that you have more control over which pages are crawled or not crawled.<\/span><\/p>\n
