What Is a Slug and How to Create an Effective Slug

Introduction

When building a website, writing blog posts, or creating an online course, we often spend a lot of time on titles, content, images, and lesson structure. However, there is one small detail that is frequently overlooked: the page URL—more specifically, the slug.

Many content creators run into issues such as:

Letting the slug be automatically generated from a very long title
URLs containing hard-to-read and hard-to-remember characters
As content grows, being unable to tell links apart

Meanwhile, slugs directly affect:

How Google understands and ranks your content
The reader’s experience when seeing and sharing a link
Long-term content management on a website or an online learning platform like Ourdemy

That’s why understanding what a slug is and setting it properly from the beginning can save you a lot of time later, while also making your content more professional and scalable.

1. What Is a Slug?

A slug is the text at the end of a URL that identifies and describes the main content of a page or post.

🔹 Where the slug appears in a URL

Example:

https://ourdemy.com/blog/how-to-choose-lesson-format

In this URL:

https://ourdemy.com → domain (website)
/blog/ → category
how-to-choose-lesson-format → slug

In other words, the slug is the “technical name” of a page on the Internet, used by:

Users
Search engines (Google, Bing, etc.)
Content management systems (CMS, LMS)

🔹 Slug vs. post title

This is a common point of confusion for beginners.

Criteria	Title	Slug
Purpose	Attract attention, convey a message	Identify the content
Length	Flexible	Should be short
Format	Can include punctuation, emotion, questions	No accents, no special characters
Changes	Can be changed	Should not be changed after publishing

Example:

Title:
How to Choose a Lesson Format: Text, Slides, or Video?
Appropriate slug:
choose-lesson-format

👉 Titles are for reading, slugs are for understanding and managing.

2. How Do Slugs Affect SEO and User Experience?

🔹 Impact on SEO

Slugs help Google:

Understand the main topic of a page more quickly
Identify the primary keyword
Evaluate relevance between different pieces of content

Example:

Slug: what-is-a-slug
→ Google immediately understands the page is about the concept of a slug
Slug: post123-new-update
→ Google gets no clear information

Slugs are not the strongest SEO factor, but they are a foundational element. When done well, they strongly support later SEO efforts.

🔹 Impact on reader experience

Readers often:

Look at the link before clicking
Read the link when it’s shared via chat
Try to remember the link to come back later

Compare:

❌

ourdemy.com/blog/2024/05/abcxyz?id=123

✅

ourdemy.com/blog/what-is-a-slug

Clear slugs make links:

Easier to understand
Easier to remember
Easier to share
More professional and trustworthy

🔹 Impact on click-through rate (CTR)

When a URL appears on Google Search or social media:

Readable slugs → higher chance of clicks
Messy slugs → lower trust

The slug is part of your content’s first impression.

3. Principles for Creating an Effective Slug

🔹 3.1. Short, concise, focused on the core idea

A slug doesn’t need to be as detailed as the title.

Ask yourself:

“If I keep only the most important idea, what is this post about?”

Example:

Title:
Using AI to Write Answer Keys and Grading Guidelines for New Teachers
Slug:
ai-answer-keys-grading

🔹 3.2. Include the main keyword (if applicable)

If your post targets a specific keyword, include it in the slug.

Example:

Target keyword: lesson file naming
Slug:
lesson-file-naming

No need to stuff keywords—one main keyword is enough.

🔹 3.3. No accents, no special characters

A standard slug should be:

Lowercase
Without accents
Without spaces
Using hyphens to separate words

❌ What is a Slug?
❌ slug_is_what!!!
✅ what-is-a-slug

🔹 3.4. Avoid unnecessary words

You can remove words like:

and, is, of, with, for, those, these

Example:

❌
what-is-a-slug-and-how-to-create-an-effective-slug-for-your-website

✅
what-is-a-slug-how-to-create

🔹 3.5. Fix the slug from the beginning

Changing a slug after publishing can:

Cause 404 errors
Lose SEO traffic if redirects are not set properly

👉 For pillar blogs, landing pages, lessons, or courses, decide the slug before publishing.

4. Common Mistakes When Creating Slugs

Common beginner mistakes include:

Slugs that are too long
Slugs unrelated to the content
Automatically generated ID-based slugs
Using accented or special characters
Including unnecessary dates or numbers
Changing slugs multiple times

These issues won’t break your website immediately, but over time they will:

Make content harder to manage
Limit scalability
Look unprofessional to readers and Google

Conclusion

Slugs Are Simple but Have Long-Term Impact

Slugs are not complex or highly technical. In reality, they reflect how carefully and systematically you approach content creation from the start. When slugs are clear and consistent, you’re laying a strong foundation for future content management and growth.

At their core, slugs represent:

A habit of creating well-organized content
A preparation step for the long-term future of your website and courses

For teachers and online course creators on Ourdemy, clear slugs make blogs and lessons easier to manage and expand—without having to restructure existing content. At the same time, your website looks more professional and trustworthy from the very first posts.

👉 Getting the slug right at publishing time is a small step, but it will save you a great deal of effort throughout your entire course creation and growth journey.
