Your Guide to Redirecting Query Parameters!
When managing a website, it’s common to end up with URLs that contain messy query string parameters. Handling the original url correctly when redirecting traffic is crucial to ensure seamless navigation and avoid potential issues. You may have links like “page.html?source=google&id=123” lingering around. Or perhaps your site architecture has changed and old parameter-based URLs need to redirect to new cleaner pages.
While query strings can serve a purpose, excessive use of parameters in URLs can create complications for navigation, SEO, and overall user experience. Luckily, there are techniques to redirect these URLs to clearer structures.
What are Query String Parameters?
Query string parameters are additional pieces of data appended to the end of a URL, starting with a question mark (?). They allow you to pass variables and values into a webpage.
For example, you may see a URL like this: example.com/page?color=blue&size=large Here, “color=blue” and “size=large” are query string parameters that pass data to the page. The page could then use this data to customize the display, pulling the color and size values from the source URL.
Query strings are commonly used for search filters, personalization, tracking, and more. They enable dynamic interactions without having to create separate pages.
Why Should You Redirect URLs with Query String Parameters?
Redirecting URLs with query string parameters enables a few unique use cases including:
- Campaign tracking: If you are running paid advertising campaigns on a separate domain, redirecting the URLs with campaign tracking parameters (such as utm_source, utm_medium, utm_campaign) allows you to preserve the campaign attribution when users click through to your main website. This ensures you can properly track traffic sources and analyze campaign performance in analytics tools like Google Analytics while preserving the user experience.
- URL cleanup: If your site URLs have changed, redirecting old query string links to new clean URLs improves the user experience. For example, redirecting “page.html?id=about” to “about-us” makes for a simpler URL that users can easily understand. This process can be challenging when trying to preserve every query param during the redirect.
- Testing parameters: For A/B tests, extra parameters are often added to identify the traffic source and steps taken by the user. You can strip these off by redirecting to a clean URL without the temporary parameters while still tracking the traffic source. However, preserving query params during these redirects can be complex and laborious.
- Required parameters: If a page needs specific query parameters to function properly, you can redirect URLs missing them. For example, redirecting “products” to “products?category=new” to default to the “new” category.
- Changing parameter structure: Redirects allow you to alter the structure of query parameters, like changing “id” to “product_id”.
At the end of the day, the goal of redirecting URLs with query string parameters is to avoid broken links and send users to the right page with the expected results.
Using .htaccess Redirects
The most common way to perform a URL redirect with query string parameters on an Apache server is by using .htaccess files. .htaccess provides a simple redirect syntax: Redirect /old-url /new-url After the directive “Redirect” you can specify an HTTP status code. Without specifying an HTTP status code, the redirect defaults to a 302 redirect. So, to create a 301 redirect, you can use the following syntax: Redirect 301 /old-url /new-url
How to Redirect URLs with Query String Parameters Using .htaccess
For URLs with query strings, you can redirect based on parameter matches. For example: Redirect 301 /page.html?id=about&type=old /about-us This example redirects any “/page.html” URL with the query string parameters “id=about” and “type=old.” The URL can contain additional query string parameters as well. As long as it contains these two query string parameters, the page will be redirected to the defined redirect page “/about-us.”
When using .htaccess redirects, keep these notes in mind:
- Use the full URLs including the domain, not just local page paths.
- 301 redirects are permanent, 302 redirects are temporary.
- Additional parameters can be passed through or appended to the new URL.
- Test carefully, as redirects can cause infinite loops if configured incorrectly.
For complex redirect configurations, it is important to consult the support team to ensure everything is set up correctly.
Regular Expression Matching
For more complex redirect scenarios, regular expressions can be used to precisely match and manipulate query string patterns and query params with the RedirectMatch directive. For example: RedirectMatch 301 “(.).docx$” “$1.html”* This would redirect all Word documents with a .docx file type to HTML pages with the same name.
The key difference between RedirectMatch and Redirect is that RedirectMatch utilizes regex for pattern matching. It also supports back-references like $1 and $2 to capture groups from the regex pattern and insert them into the new redirect URL. For example: RedirectMatch 301 “/file=(.)” “/new-file?id=$1”* This captures the file parameter value to reuse in the redirected URL. You can use multiple capture groups and backreferences sequentially - (group1) (group2) - referred to as $1, $2.
With strategic regex, you can flexibly match legacy URL patterns and programmatically generate cleaner redirected URLs.
