E-commerce websites can create thousands or even millions of URLs. This happens because of filters, sorting options and different URL parameters. Many of these URLs help shoppers find what they are looking for.. They can also cause big technical SEO problems if search engines are allowed to crawl every single one.
When crawlers spend much time on weak or duplicate URLs important product and category pages may not get enough attention. This means the search engines might not discover or update them often as they should.
How Faceted URLs Waste Crawl Resources
Imagine a store with a category page:
example.com/shoes
Users can filter this page by:
- Color
- Size
- Brand
- Price
- Rating
- Sorting
This can lead to URLs like:
/shoes?color=black
/shoes?size=10
/shoes?color=black&size=10
/shoes?sort=price-low
If the site allows all combinations thousands of URLs can be created. Search engines may end up visiting pages that have almost the same content.
Why Thin and Duplicate URLs Matter
Many of these filtered URLs do not add value compared to the main category page. For example consider these two URLs:
/shoes?color=black
/shoes?color=black&sort=popular
They might show the same products. Allowing all such variations to be leads to too many URLs. This increases the number of URLs that search engines need to process.
The bigger the site the worse this problem becomes. A large site can quickly build up a number of unneeded URLs. This makes it harder for search engines to focus on the important pages.
Impact on Important Pages
When search engines waste time crawling duplicate URLs important pages get less attention. These can include:
- Product pages
- Main category pages
- Subcategory pages
- inventory pages
- Important landing pages
The result is slower discovery and less efficient crawling across the website. Search engines might not find content quickly. They might not re- important pages often enough.
It’s worth noting that crawl budget is not usually an issue for small websites.. For large websites or ones that change often it becomes a serious concern.
How to Reduce Crawl Budget Waste
Control Unnecessary Parameters
Look for URL parameters that don’t add value. Examples include sorting options, tracking codes or temporary filter combinations. These should not be allowed to create crawlable URLs.
Use Canonical Tags
When pages are very similar use tags to tell search engines which one is the main version. This helps avoid content issues.
Improve Internal Linking
Avoid creating many crawl paths through filter combinations. Focus internal links on pages. This helps search engines find content faster.
Use Appropriate Indexing Controls
Pages that don’t add value on their own should not be open to crawling. Use robots.txt, noindex tags or other tools to manage them properly.
Monitor URL Patterns
Regularly check the website’s crawl data. Look for spikes in parameter-based URLs. This helps catch problems
Practical Example
An online store has 20,000 products.. It creates 2 million filter URLs. A crawler might visit thousands of combinations involving color, size, price and sorting. It may not reach some less linked product pages.
The solution is to manage URLs. Keep the most useful ones. Make sure search engines can easily find product and category pages.
How a Website Audit Helps
A Website Audit Service* can help find issues like too many parameter URLs, duplicate content, weak internal links and crawl problems. It can also show which URL patterns should stay accessible and which should be blocked.
A technical audit gives a picture of how search engines are experiencing the site. It helps set rules for crawl efficiency.
Uncontrolled faceted navigation can turn an e-commerce site into a large collection of thin and duplicate URLs. This makes crawling inefficient. Can hurt visibility.
By managing parameters using canonical tags correctly improving internal links and watching crawl patterns businesses can help search engines focus on their most important pages.
