How to remove the querystring and get only the URL
Have you ever shared a link and noticed a jumble of characters after the main URL, also known as a querystring? These querystrings, often starting with a question mark (?), can contain tracking parameters, session IDs, or other data that, while useful for analytics, can make your URLs look messy and less shareable. In many situations, you might want to remove the querystring and get only the URL. This process not only cleans up the appearance of your links but can also improve user experience and potentially boost your SEO. Removing unnecessary parameters ensures that the core content is easily identifiable, making it easier for both users and search engines to understand the page’s purpose. This article will guide you through various methods to achieve this, ensuring your URLs are pristine and focused on delivering value.
Why Remove the Querystring?
Removing the querystring from a URL offers several benefits. First and foremost, it enhances the user experience. Shorter, cleaner URLs are easier to read, remember, and share. Users are more likely to trust and click on a link that looks straightforward and professional. For example, a URL like example.com/product?utm_source=facebook&utm_medium=cpc is less appealing than example.com/product. A study by Backlinko found that shorter URLs tend to perform better in search results, likely due to their improved readability and shareability [1].
Another key advantage is improved SEO. While search engines can handle URLs with querystrings, they prefer clean, semantic URLs. When you remove the querystring, you ensure that search engines focus on the core content of the page rather than potentially irrelevant parameters. This can lead to better indexing and ranking. Additionally, cleaner URLs are easier to track and analyze in analytics platforms. You can more accurately attribute traffic to specific sources without being bogged down by extraneous parameters. Consider a case study where a website cleaned up its URLs and saw a noticeable increase in organic traffic within a few months.
Finally, removing the querystring can help prevent duplicate content issues. If different URLs with the same content but different parameters are indexed, search engines may see them as duplicate pages, which can negatively impact your SEO. By ensuring that only the clean URL is indexed, you avoid this potential problem. This practice aligns with Google’s recommendations for URL structure, emphasizing simplicity and relevance [2].
Methods to Remove the Querystring
There are several methods you can use to remove the querystring from a URL, depending on your technical expertise and the specific situation. One common approach is using server-side scripting languages like PHP or Python. These languages allow you to programmatically manipulate URLs and redirect users to the clean version.
For example, in PHP, you can use the $_SERVER['REQUEST_URI'] variable to access the full URL and then use string manipulation functions to remove the querystring. You can then redirect the user to the cleaned URL using the header() function. This method is particularly useful for dynamic websites where URLs are generated programmatically. Here’s a basic example:
<?php $url = $_SERVER['REQUEST_URI']; $clean_url = strtok($url, '?'); header("Location: " . $clean_url); exit(); ?>
Another approach is using URL rewriting rules in your web server’s configuration file (e.g., .htaccess for Apache or web.config for IIS). These rules allow you to define patterns that match URLs with querystrings and redirect them to the corresponding clean URLs. This method is typically more efficient than server-side scripting because the redirection is handled directly by the web server. For example, in Apache, you can use the following .htaccess rule:
RewriteEngine On RewriteCond %{QUERY_STRING} !^$ RewriteRule ^(.)$ /$1? [R=301,L]
This rule removes any querystring from the URL and redirects the user to the clean version using a 301 redirect, which is important for SEO as it tells search engines that the page has permanently moved to the new URL. This ensures that any link equity is transferred to the clean URL.
Using JavaScript to Remove the Querystring
While server-side methods are generally preferred for SEO and performance reasons, you can also use JavaScript to remove the querystring from the URL on the client-side. This can be useful in situations where you don’t have control over the server configuration or when you need to manipulate the URL dynamically based on user interactions.
The simplest way to achieve this with JavaScript is to use the window.location object. You can access the current URL using window.location.href and then use string manipulation methods to remove the querystring. Finally, you can update the URL using window.location.replace(), which replaces the current URL in the browser’s history without triggering a full page reload. This method provides a smoother user experience compared to a full redirect.
Here’s an example of how to do this:
<script> var url = window.location.href; var clean_url = url.split('?')[0]; window.history.replaceState({}, document.title, clean_url); </script>
This code snippet first gets the current URL, then splits it at the question mark to separate the base URL from the querystring. Finally, it uses window.history.replaceState() to update the URL in the browser’s address bar without reloading the page. This method is less impactful for SEO since the server never sees the cleaned URL, but it can still improve the user experience by presenting a cleaner URL to the user. It’s important to note that this method only changes the URL in the browser; it doesn’t affect how the server handles the request.
Best Practices and Considerations
When removing the querystring, it’s essential to follow best practices to avoid any negative impact on your website’s functionality or SEO. Always use 301 redirects for permanent redirects. This tells search engines that the page has permanently moved to the new URL, ensuring that any link equity is transferred. Avoid using 302 redirects unless the change is temporary.
Before implementing any URL changes, thoroughly test your website to ensure that all links are working correctly and that no functionality is broken. Pay particular attention to forms, e-commerce checkout processes, and other critical features that rely on URLs with querystrings. It’s also a good idea to monitor your website’s analytics after making URL changes to ensure that there are no unexpected drops in traffic or conversions.
Consider using canonical tags (<link rel="canonical" href="URL">) to tell search engines which version of a URL is the preferred one. This is particularly useful when you have multiple URLs with the same content but different parameters. The featured snippet paragraph is below:
Canonical tags help prevent duplicate content issues and ensure that search engines consolidate ranking signals to the preferred URL. Removing the querystring often involves setting the canonical URL to the clean URL, signaling to search engines that this is the version they should index and rank. This is a crucial step in maintaining SEO performance while cleaning up your URLs. Remember that consistency is key; ensure that the canonical URL is consistent across all pages and that it matches the URL structure you’re aiming for.
- Use 301 redirects for permanent changes.
- Test thoroughly after implementing changes.
FAQ: Removing Querystrings
- Why are querystrings added to URLs?
- Querystrings are used to pass data to a web server, such as tracking parameters, session IDs, or search queries.
- Will removing querystrings hurt my SEO?
- No, if done correctly with 301 redirects and canonical tags, **removing the querystring** can actually improve your SEO.
- Is it always necessary to remove querystrings?
- No, it depends on the specific situation. If the querystring is essential for the functionality of the page, you should not remove it. However, if it's only used for tracking or analytics, it's often safe to remove.
- Cleaner URLs improve user experience.

Canonicalization. Retrieved from [https://moz.com/learn/seo/canonicalization](https://moz.com/learn/seo/canonicalization) Question & Answer :
I’m using PHP to build the URL of the current page. Sometimes, URLs in the form of
www.example.com/myurl.html?unwantedthngs
are requested. I want to remove the ? and everything that follows it (querystring), such that the resulting URL becomes:
www.example.com/myurl.html
My current code is this:
<?php function curPageURL() { $pageURL = 'http'; if ($_SERVER["HTTPS"] == "on") { $pageURL .= "s"; } $pageURL .= "://"; if ($_SERVER["SERVER_PORT"] != "80") { $pageURL .= $_SERVER["SERVER_NAME"] . ":" . $_SERVER["SERVER_PORT"] . $_SERVER["REQUEST_URI"]; } else { $pageURL .= $_SERVER["SERVER_NAME"] . $_SERVER["REQUEST_URI"]; } return $pageURL; } ?>
You can use strtok to get string before first occurence of ?
$url = strtok($_SERVER["REQUEST_URI"], '?');
strtok() represents the most concise technique to directly extract the substring before the ? in the querystring. explode() is less direct because it must produce a potentially two-element array by which the first element must be accessed.
Some other techniques may break when the querystring is missing or potentially mutate other/unintended substrings in the url – these techniques should be avoided.
$urls = [ 'www.example.com/myurl.html?unwantedthngs#hastag', 'www.example.com/myurl.html' ]; foreach ($urls as $url) { var_export(['strtok: ', strtok($url, '?')]); echo "\n"; var_export(['strstr/true: ', strstr($url, '?', true)]); // not reliable echo "\n"; var_export(['explode/2: ', explode('?', $url, 2)[0]]); // limit allows func to stop searching after first encounter echo "\n"; var_export(['substr/strrpos: ', substr($url, 0, strrpos( $url, "?"))]); // not reliable; still not with strpos() echo "\n---\n"; }
Output:
array ( 0 => 'strtok: ', 1 => 'www.example.com/myurl.html', ) array ( 0 => 'strstr/true: ', 1 => 'www.example.com/myurl.html', ) array ( 0 => 'explode/2: ', 1 => 'www.example.com/myurl.html', ) array ( 0 => 'substr/strrpos: ', 1 => 'www.example.com/myurl.html', ) --- array ( 0 => 'strtok: ', 1 => 'www.example.com/myurl.html', ) array ( 0 => 'strstr/true: ', 1 => false, // bad news ) array ( 0 => 'explode/2: ', 1 => 'www.example.com/myurl.html', ) array ( 0 => 'substr/strrpos: ', 1 => '', // bad news ) ---
