How to Restore Default Robots.txt File in Shopify
Shopify’s Default Robots.txt Configuration
Shopify automatically generates a robots.txt file that sets basic rules for how search engines interact with your store. While this default setup covers the essentials, most stores will need some adjustments to fully optimize it for their needs [1].
Key Features of Shopify’s Robots.txt
The default configuration includes a few critical directives:
| Directive | Purpose |
|---|---|
| User-agent: * | Applies rules to all bots |
| Allow: /products | Enables crawling of product pages |
| Disallow: /admin | Blocks access to the admin area |
| Sitemap: yourstore.com/sitemap.xml | Points to the store’s sitemap |
This setup focuses on protecting sensitive areas like the admin section while ensuring important e-commerce pages, such as product pages, remain accessible. For collections, Shopify adds specific rules to avoid duplicate content caused by filtered or sorted pages:
Disallow: /collections/*+*
Disallow: /collections/*%2[bB]*
(blocks filtered collection variants)
These directives help search engines prioritize the right content without indexing unnecessary duplicates [1][2].
Challenges with the Default Configuration
While Shopify’s robots.txt file provides a good starting point, it does have some limitations that store owners should be aware of:
- Limited Customization: Until recently, Shopify restricted direct edits to the robots.txt file, making it harder to address specific needs [1].
- Crawl Rate Control: The default setup doesn’t allow for detailed control over crawl rates or bot-specific rules, which could affect site performance during high-traffic periods [1][2].
- Potential Over-Blocking: Certain rules, like those for filtered collections, might unintentionally block legitimate pages, especially if your store uses custom filtering or unique URL structures [1][2].
These limitations often lead to issues that require further troubleshooting, which we’ll explore next.
Finding Robots.txt Problems
Spotting robots.txt issues early can help keep your Shopify store’s SEO on track. These methods build on Shopify’s default configuration challenges mentioned earlier.
Google Search Console Error Detection
Google Search Console’s Coverage Report is a great starting point:
- Head to the Coverage Report and look under "Excluded" pages.
- Use the URL Inspection Tool to analyze specific URLs.
The URL Inspection Tool pinpoints the exact line in your robots.txt file that’s causing the problem, making it easier to address the issue [1].
Robots.txt Code Check
Google’s Robots.txt Tester is handy for checking your file’s setup:
- Test live URLs against your current rules.
- Simulate how different crawlers interact with your site.
- Check for syntax or formatting errors.
For a deeper dive, tools like Screaming Frog can scan your entire store and flag URLs impacted by robots.txt directives [4].
Common Shopify Robots.txt Errors
Here are some typical robots.txt problems Shopify stores face:
| Error Type | Impact | Detection Method |
|---|---|---|
| Missing Sitemaps | Limits content discovery | Sitemap validation |
| Blocking CSS/JS files | Hurts page rendering | Screaming Frog analysis |
Once you’ve identified these issues, performing regular audits can help you spot unexpected changes that might introduce new blocking rules. These proactive checks are key to maintaining your store’s visibility [1][4].
How to Edit Robots.txt.liquid in Shopify
Once you’ve identified the necessary changes using the error detection methods discussed earlier, follow these steps to update your robots.txt.liquid file.
Backing Up and Accessing the File
Before making any changes, it’s essential to back up your theme. Here’s how to access the file:
- Go to Shopify Admin: Navigate to Settings > Apps and sales channels > Online Store > Themes.
- Use the Actions menu to create a new ‘robots’ template.
Updating the Code
To ensure Shopify’s automatic updates remain functional, use Liquid syntax when editing your file. Here’s an example:
User-agent: *
Disallow: /admin/
Disallow: /cart/
Allow: /products/
Allow: /collections/
{% if request.host contains 'myshopify.com' %}
Disallow: /
{% endif %}
For specific collections, you can add rules like this:
{% if collection.handle == 'private-collection' %}
Disallow: /collections/private-collection
{% endif %}
Adding Sitemap Links
Ensure all sitemaps are included to improve discoverability:
Sitemap: {{ shop.url }}/sitemap.xml
Sitemap: {{ shop.url }}/sitemap_products_1.xml
Sitemap: {{ shop.url }}/sitemap_collections_1.xml
Validating Changes
After making modifications, use Google’s robots.txt testing tool [3] to verify your updates.
"It’s strongly not recommended to delete the contents of the template and replace it with plain text rules, as this may lead to outdated rules and prevent Shopify from applying SEO best practices over time" [3].
Fix and Prevent Common Errors
Building on the file editing process outlined earlier, these tips will help you maintain crawl efficiency. Once you’ve made your robots.txt edits using the methods shared above, check that these adjustments address common issues effectively.
Error and Solution Reference Table
| Error Type | Common Example | Solution | SEO Impact |
|---|---|---|---|
| Accidental Page Blocking | Disallow: /products/ |
Remove or adjust directive | Reduced visibility |
| Conflicting Directives | Allow: /* and Disallow: /* |
Eliminate conflicting rules | Indexing problems |
| Incorrect Wildcard Usage | Disallow: /*.php$ |
Use more precise patterns | May block key pages |
| Syntax Formatting | user-agent: * (lowercase) |
Correct to User-agent: * |
Misinterpreted rules |
Code Writing Best Practices
Keep these simple rules in mind for effective robots.txt file management:
Use Proper Formatting and Syntax
User-agent: *
Allow: /
Disallow: /admin/
Disallow: /cart
Order Rules from Specific to General
Disallow: /collections/private-sale/*
Allow: /collections/
Ensure Consistent Rules
Disallow: /*?sort_by=
Disallow: /*?page=
Test Regularly
Always test changes before rolling them out. Use tools like Google Search Console to monitor crawl stats and identify issues.
