How to Guide Googlebot in Crawling Important URLs

How to Guide Googlebot in Crawling Important URLs

SEO success extends beyond quality content—it requires a deep understanding of technical elements like crawling. If we look at the initial stage of Google’s process, crawling lays the groundwork for indexing and ranking. Together, these determine your SERP potential.

However, before content can be indexed, it must first be crawled. And when you’re dealing with limited crawl budgets on JavaScript-heavy websites, crawl budget efficiency becomes vital.

In this blog post, we will discuss the fundamentals of crawl efficiency and how to guide Googlebot in crawling certain web pages. We’ve also included both reactive solutions, like the identification and removal of low-value pages, as well as proactive strategies, like prerendering.

Understanding Crawl Efficiency

By now, you know that Google assigns a specific crawl budget to each website, indicating the number of URLs crawled per cycle. But crawl efficiency, on the other hand, refers to the effective use of your crawl budget. It heavily influences the way Google discovers and indexes your new or updated content.

Here are some other factors that influence crawl efficiency.

The Crawl Rate Limit

According to Google, the crawl rate limit is the “maximum fetching rate for a given site.”

This limit isn’t static across all sites and is determined by several factors, including your server’s health status and the use of redirects. A responsive server with few errors increases Googlebot’s crawl rate limit, enabling it to crawl a larger number of your URLs.

A common reason for hitting the crawl rate limit quickly is redirects. While redirects help Google when content moves to a new URL, the overuse of this setting can quickly eat into your crawl budget.

Optimizing your redirect chains can conserve your crawl budget and improve crawl efficiency, e.g. by making sure to update navigation links with the new URL instead of relying on redirects.

To add, Googlebot favors fresh content and frequently updated sites. Regular updates signal to Googlebot that your site likely requires more frequent crawls.

Clear and Logical Structure

A well-structured site acts as an easy-to-follow roadmap.

If there’s proper internal linking, even better! The reason for this is it will guide Googlebot to crucial pages, reducing time spent on low-value ones. You can also instruct Googlebot on which pages to crawl and index by using Robots Meta Tags like no-index or no-follow. For instance, placing nofollow on your /blog page in favor of relying on category pages, providing Googlebot with more context when crawling blog posts. Of course, this would require proper linking to category pages to be efficient.

Moreover, a clean and logical URL structure promotes efficient crawling and indexing, as a well-structured URL that accurately represents its content helps Googlebot understand and index it.

Identify and Remove Low-Value Pages

Low-value pages typically include outdated promotions, thin content with minimal or no value, duplicate content resulting from URL parameter issues, and dynamically generated pages that don’t offer unique value. When Googlebot spends its time crawling these pages, your crawl budget is quickly exhausted.

Familiarize Yourself with Google’s Quality Guidelines

Firstly, it’s essential to familiarize yourself with Google’s Quality Guidelines. By understanding these guidelines, you can discern pages that might not meet Google’s standards. Aim to align your content with these guidelines, ensuring that your website is in line with Google’s preferred standards.

For instance, duplicate content can hinder your SEO efforts, leading to lower rankings.

You can make use of tools such as Seobility to identify and address duplicate content across your site. By ensuring each page features unique and relevant content, you reduce the number of pages Googlebot will have to crawl, and you amplify the potential for every page to rank well in search engine results.

Every page should serve a clear, valuable purpose for users. Pages with duplicated content, auto-generated pages, or those that don’t provide a unique service or information often fall into the low-value category. Regularly evaluate the purpose of your pages to ensure they are user-centric and contribute positively to your overall website strategy.

Utilize Tools and Techniques

Google Analytics can provide valuable insights into pages that users find less valuable. Metrics like bounce rates and average time on page can hint at user dissatisfaction with certain pages. High bounce rates and low average time on page typically point towards content that doesn’t meet user expectations. However, remember to consider all factors, as a high bounce rate may just mean that users found their answers quickly.

SEO auditing tools, like SEMrush and Ahrefs, can be incredibly helpful in identifying low-value pages. These tools provide comprehensive site audits, highlighting issues like poor keyword rankings, broken links, and weak backlink profiles. Regular audits help you keep track of your pages’ performance, allowing you to promptly address any issues that arise.

For a quick-and-easy fix, you can use a no-index tag for single pages, and robots.txt for entire directories or single pages. With these, you can block Googlebot from crawling low-value pages, guiding it instead to the more important and valuable sections of your site. To be clear, cleaning up and optimizing your site as a whole is the preferred approach, but simply blocking low-value pages may be a good first step.

Your Sitemap is Key to Crawl Budget Optimization

Your sitemap.xml file serves as a roadmap to your site’s most critical pages for Googlebot. However, there’s a trove of opportunities lying beneath the surface that can be harnessed to maximize your crawl budget. (*Note that sitemaps are particularly crucial for large websites, new websites, sites with large archives, or sites using rich media or appearing in Google News.) In these cases, a well-structured and regularly updated sitemap.xml file can significantly enhance crawl efficiency.

Effective Use of XML Tags

XML tags can serve as guiding beacons for Googlebot. For instance, the <priority> tag allows you to indicate the importance of each page relative to other pages on your site. This doesn’t necessarily guarantee these pages will be crawled more often, but it signals to Googlebot which pages you deem most important.

The <lastmod> tag is another useful tag, as it provides Googlebot with the date a page was last modified. As Googlebot prefers fresh content, making regular updates and correctly utilizing the <lastmod> tag can attract more crawls to your important pages.

It’s also possible to include more than URLs in your sitemap. By incorporating media such as images and videos using <image:image> and <video:video> tags, you can enhance Googlebot’s discovery and indexing of these resources. This can be especially useful if your site relies heavily on rich media to engage users, or if you’re using Javascript to load images after the page has rendered, as Google won’t see those.

Structure Your Sitemap

A single sitemap.xml file can contain up to 50,000 URLs, but this doesn’t necessarily mean you should aim to reach this limit. Overloading your sitemap could potentially lead to slower load times and an inefficient crawl. Keep your sitemap lean and focused on your most important pages to ensure optimal crawl efficiency.

Consider segmenting your sitemap by content type, such as blog posts, product pages, and others. For larger sites boasting numerous sitemaps, a sitemap index file is often preferred. A sitemap index file is essentially a sitemap of sitemaps, allowing you to neatly organize your multiple sitemaps and guide Googlebot through them effectively. This ensures even your largest websites are crawled and indexed efficiently.

Test Before You Submit

Lastly, always remember to test your sitemap for errors using Google Search Console before submitting it. This preemptive measure can save you from potential pitfalls down the line and ensure Googlebot can crawl your sitemap as intended.

The JavaScript Challenge

JavaScript’s loading can delay the rendering of content on your pages.

Googlebot, on a tight crawl budget, might not wait for these elements to load, leading to missed content and a less accurate representation of your page in Google’s index. The question is, how can we mitigate this issue? The answer lies in two primary solutions: dynamic rendering and prerendering.

Dynamic rendering involves serving a static HTML version of your page to bots while delivering the usual JavaScript-heavy page to users. However, as stated in the official Google documentation, dynamic rendering is a workaround, given the complexity of implementation. Conversely, open-source tools like Prerender make the process effortless.

The prerendering process detects whether a user or a bot is requesting a page, ensuring that the 100% cached version is served to bots and the dynamic one to users. Prerendering also impacts perceived page speed as Googlebot receives a fully rendered HTML snapshot, indirectly boosting your SEO.

Services like Single Page Applications (SPAs) present a unique scenario. These applications heavily rely on JavaScript, making them particularly susceptible to crawl issues. However, prerendering ensures that all content of a SPA is discoverable by Googlebot. And, as prerendering can be implemented on your CDN—e.g. by using Cloudflare Workers—getting it implemented requires no code changes or support for specific frameworks like React or Vue.

Start Optimizing Crawl Budget and Efficiency

The process of guiding Googlebot to effectively crawl important URLs is no easy task, but it’s one well worth undertaking. By identifying and blocking low-value pages, optimizing your sitemap.xml, and embracing prerendering services, you can enhance your crawl efficiency and boost SEO performance.
