Google’s New Guide to Faceted Navigation Explained

Google has released a new help document on faceted navigation, a feature frequently used on e-commerce, article, and event websites. While faceted navigation is an excellent tool to improve user experience by helping visitors filter and find relevant content, Google cautions that improper implementation can lead to serious SEO problems. These issues arise when faceted navigation generates an overwhelming number of URLs, often creating near-infinite spaces that harm a website’s overall performance.

In a blog post announcing the document, Google’s Gary Illyes explained the risks associated with mishandling faceted navigation. He stated, “Faceted navigation is a great way to help users find what they need on your site, but it can create an SEO nightmare if not implemented carefully.”

Google highlighted two significant issues that can arise:

Overcrawling: When faceted navigation generates too many unnecessary or repetitive URLs, search engines end up wasting resources crawling pages that offer no real value to users. Instead of focusing on your site’s most important content, search engines spend time navigating countless URLs, ultimately hampering efficiency.
Slower Content Discovery: Overcrawling slows down the process of identifying and indexing important or new pages on your site. As a result, fresh content that could otherwise rank well in search results might take longer to appear in search engine indexes, delaying your site’s ability to attract organic traffic.

This guidance on faceted navigation builds on Google’s earlier advice published back in 2014. The latest documentation serves as an updated reference for site owners and SEO professionals to avoid pitfalls caused by poorly managed navigation structures. By following Google’s best practices, businesses can ensure that their faceted navigation not only enhances user experience but also aligns with search engine optimisation goals.

To safeguard against overcrawling and slow content discovery, site owners are encouraged to proactively review their faceted navigation setup. This includes limiting the generation of unnecessary URLs, implementing canonical tags, or using other appropriate tools to manage crawl efficiency. With a careful approach, faceted navigation can work to the advantage of both users and search engines, improving site performance and visibility.

By addressing these challenges, businesses can strike the right balance between delivering a user-friendly browsing experience and maintaining a search engine-friendly website structure. Google’s latest guidance serves as a timely reminder to prioritise both technical SEO and user satisfaction.

What Google Recommends

Google has outlined clear recommendations for managing faceted navigation to avoid significant SEO pitfalls. Faceted navigation, commonly used on e-commerce websites, article directories, and event platforms, allows users to refine their searches through filters. However, if not managed carefully, it can create challenges for search engines, particularly with crawling and indexing large volumes of URLs.

Google’s advice is straightforward:

If faceted navigation URLs do not need to be indexed, block search engines from crawling them. This prevents search engines from wasting resources on pages that are unnecessary for search users.
If faceted navigation URLs need to be indexed, ensure the URLs comply with Google’s best practices to optimise efficiency and reduce the burden on search engines.

Gary Illyes from Google explained the importance of this distinction. Crawling faceted URLs can lead to significant resource consumption due to the sheer number of possible URL combinations and the operations required to load these pages. When not managed correctly, this overloading can slow down the discovery of critical content on your website, making it harder for search engines to prioritise and index your most important pages.

More Details on Google’s Recommendations

Google’s updated help document goes into further detail about methods for managing faceted navigation to reduce potential issues. There are two main approaches:

Preventing Crawling
If faceted URLs do not need to appear in search results, you can prevent crawling by using strategies such as:
- Robots.txt to block specific patterns of URLs.
- Using “nofollow” attributes for links to faceted navigation pages.
- Canonical tags to direct search engines to a preferred version of the URL.
  These methods ensure search engines do not waste time crawling unnecessary URLs that add no value for users.
Optimising Indexed URLs
When faceted URLs must be indexed, Google recommends following specific best practices to keep the URL structure clean and efficient. This may include:
- Limiting the number of combinations for faceted URLs.
- Avoiding duplicate or overly similar URLs.
- Ensuring parameters are clearly defined and provide distinct value.

Why This Matters for Website Owners

Faceted navigation is an incredibly useful tool for users, as it helps them narrow down searches and find exactly what they need. However, from an SEO perspective, it can become a nightmare if left unmanaged. Poorly optimised faceted navigation can:

Overwhelm search engines with an infinite number of URL variations, leading to “overcrawling.”
Slow down the discovery of important, fresh content because search engines are busy crawling less relevant URLs.
Consume computing resources, which can impact overall site performance and efficiency.

For website owners, this issue is particularly relevant on platforms that generate large amounts of URLs through filters or sorting options. E-commerce websites, for example, often allow users to refine searches by size, colour, price, and more. Similarly, event sites and article directories allow filtering by date, topic, or location. While these tools improve user experience, they also produce countless URL variations that can quickly become problematic for SEO.

Staying Ahead with Google’s Best Practices

Many experienced SEO professionals and website managers already have strategies in place to address faceted navigation challenges. These include implementing crawl directives, canonical tags, and regularly monitoring URL parameters. However, Google’s updated recommendations provide valuable insights and reflect the most current best practices for handling this issue effectively.

If you’re responsible for managing an e-commerce site, a news portal, or any platform with faceted navigation, it’s worth revisiting your current approach. Google’s guidance can help ensure your website is optimised for search engines while maintaining a seamless experience for users.

Final Thoughts

By proactively managing faceted navigation, you can avoid overloading search engines with unnecessary URLs and focus on improving the discoverability of your most valuable content. Whether you block unnecessary URLs from being crawled or optimise those that need to be indexed, following Google’s recommendations is key to maintaining a healthy and efficient website.
