Why is a URL Slug crucial for SEO?

A Slug is a crucial component of website architecture with a significant impact on its search engine optimization (SEO) performance. In simpler terms, it is the portion of a URL that identifies a specific page or piece of content on a website.

One of the main reasons Slug is important for SEO is because it provides valuable information to search engines and users about the content of the webpage. When a search engine crawls a website, it analyzes the URL structure to determine what the webpage is about.

By including relevant keywords in the URL Slug, website owners can signal to search engines what their page is about and increase their chances of ranking higher in search engine results pages (SERPs).

Moreover, a well-crafted Slug can also enhance the user experience by making it easier for visitors to understand what they can expect to find on the page. This can increase click-through rates, reduce bounce rates, and ultimately improve the overall user engagement and satisfaction with the website.

7 Best Practices to create & optimize

After having a better understanding of the concept of “What is a URL Slug?” let’s take a look at the seven methods listed below to learn how to construct and optimize Slug URLs.

Be Descriptive

A well-crafted Slug can be a powerful tool in helping users and search engines understand the content of a webpage. To achieve this, it is important to be descriptive and use keywords that accurately reflect the topic of the page.

For example, if you are running a recipe website and want to create a Slug for a vegan lasagna recipe, a descriptive and unique URL Slug could be:


This URL slug is descriptive, including specific keywords such as “vegan,” “lasagna,” “tofu,” and “cashew cheese.” It also provides a unique and memorable URL that accurately reflects the content of the page.

Make it brief and simple to read

You should keep URL Slugs brief and simple to read for several reasons.

Firstly, a short and concise Slug is easier for users to read and remember. Users are more likely to click on a link with a clear and concise URL Slug, rather than a long and convoluted one. A brief and simple slug also makes it easier to share links on social media, email, or other platforms.

Secondly, a brief Slug can improve search engine optimization (SEO). Search engines use it to understand the content of the page and its relevance to a search query. A concise and relevant URL Slug with targeted keywords can improve the chances of the page appearing in search results.

Lastly, a brief and simple URL Slug is easier to maintain and update. If it is too long and complicated, it can be difficult to update or change in the future, leading to broken links and other issues.

Separate Words

Separating words in a URL slug with hyphens is an important practice for readability and clarityIt can improve the user experience and make it easier for search engines to understand the content of your pages.

Employ Hyphens rather than Underscores

One common way to separate words in a URL slug is to use hyphens (-). Hyphens are preferred over other characters like underscores (_) because they are more visually distinct and easier to read.

For instance, /making-cinnamon-rolls/, is a good Slug; not /making_cinamon_rolls/.

Use Lowercase Characters

Using lowercase characters in a URL Slug is a standard practice that can help improve consistency and readability. URLs are case sensitive, which means that using uppercase letters in a slug can create inconsistencies and confusion for users.

Additionally, lowercase characters take up less space than uppercase characters, which can make the URL Slug more concise and easier to read. A Slug with consistent lowercase characters is also more visually appealing and easier to remember.

Avoid Special Characters

Using special characters in a URL slug can cause technical issues and create inconsistencies in your website’s URL structure. Special characters such as brackets, asterisks, and question marks can interfere with the formatting of the URL and make it harder for search engines to understand the content of the page.

Additionally, special characters can create confusion and errors for users who may not be familiar with the intended use of those characters in a URL.

To ensure consistency and readability in your URL structure, it is best to avoid using special characters in your URL slug and stick to letters, numbers, and hyphens instead.

Make It Future-Proof

To make a URL slug future-proof, focus on using keywords and phrases that will remain relevant over time. This will help ensure that the slug continues to accurately describe the content of the page or resource it represents, even as the content itself evolves.

For example, instead of creating a slug like:


A better option might be:


This URL slug focuses on the core topic of the page rather than a specific year, making it more future-proof and ensuring that it remains relevant and accessible for years to come
