Understand the Settings

While converting titles, and underscored URLs into SEO-friendly dashed URLs from this tool, you have several configuration options to choose from. Understanding these settings will help you generate much better URLs for your website or blog. Here, we will list those configuration options and their functionality in detail.

Conversion Type: It has two radio options A. No Change and B. Change & Clean. The default selection is No Change. If the "No Change" option is selected, the output URLs will retain the original text case, keep empty lines and a few special characters. Use this setting if you have a website that has underscore URL structure and you want to just change that to hyphen/dash and keep everything else the same.
Click on the "Change & Clean" radio option to open more settings. These settings include:

(i) Convert to Lowercase
(ii) Remove Special Characters & Emojis
(iii) Remove Stop Words (English Only)
(iv) Clean Unnecessary Space & Dash.

(i) Convert to Lowercase: This checkbox is by default selected when you choose the "Change & Clean" radio option. When it is check-marked, the tool will generate URLs that are in lowercase letters. If you uncheck this option, the output (produced URLs) will be in the same text case that you entered in the Input textarea.

Tips: Use lowercase letters for your website or blog URLs.

(ii). Remove Special Characters and Emojis: This checkbox is by default selected. If this option is selected, the tool will remove special characters and emojis that should not be part of a URL. If you uncheck this option, the output (produced URLs) will contain some special characters.

Tips: Remove Special characters and Emojis from your website or blog URLs.

(iii). Remove Stop Words (English Only): By default, this option is Unticked (NOT selected). When it is selected, the tool will remove some Stop Words from the URL slugs. Stop words are words that are sometimes deemed unnecessary for the URL. They are also removed from URLs to shorten them.

Tips: Search engines, these days, have become far more sophisticated with the help of AI than in the past, and removing all of the Stop Words is not recommended. Our advice is to keep them if the URL does not become too lengthy. Also, do not remove them if the resulting URL slugs compromise readability.

Please note that we only remove a couple of Stop Words that do not make your URLs unreadable. That is why you can safely use this option. Out tool treats "a", "an", "and", "the", "to" as stop words.

(iv). Clean Unnecessary Space & Dash: By default, this option is ticked or selected. When it is selected, the tool will remove any empty lines and unnecessary dashes/hyphens from the output (URLs).

Also, our tool replaces some special characters like ($, €, % and so on) into their text forms to make the URL slugs more SEO-friendly and human-readable. The special characters that our tool will convert to their word forms include $: dollar, €: euro, £: pound, ¥: yen, ₹: rupee, &: and, %: percent, <: less than, >: greater than and so on.

Why Dash/Hyphen instead of Underscore in URLs?

URLs (Uniform Resource Locators) are the backbone of the internet, serving as the addresses that guide users to specific web pages. While constructing URLs, developers often face the choice between using dashes/hyphens (-) or underscores (_) to separate words. This seemingly minor decision can have significant implications for website usability, search engine optimization (SEO), and overall user experience. Here, we will explore why using dashes/hyphens in URLs is preferable to underscores, and how this simple change can positively impact your online presence.

1. Readability and Aesthetics

Dashes/hyphens provide a clear visual separation between words in a URL, making it easier for users to read and understand. In contrast, underscores can sometimes blend into the text and create confusion, especially in longer URLs.

2. Search Engine Optimization (SEO)

Search engines like Google prefer dashes/hyphens over underscores when interpreting URLs. Dashes are treated as word separators, allowing search engines to better understand the individual words in a URL and improve the page's visibility in search results. This can ultimately lead to higher search rankings and increased organic traffic.

3. Word Separation

Dashes/hyphens naturally separate words in a URL, mimicking the spacing convention used in written language. This makes the URL more human-readable and enhances accessibility for users, especially those with visual impairments who may rely on screen readers to navigate the web.

4. Compatibility with Web Technologies

Dashes/hyphens are universally recognized as word separators in web technologies such as HTML, CSS, and JavaScript. Using dashes in URLs ensures consistency across different platforms and minimizes the risk of compatibility issues when linking to or sharing web pages.

5. Consistency in Naming Conventions

Adopting dashes/hyphens as the standard word separator in URLs promotes consistency in naming conventions across your website. Consistency simplifies website maintenance, improves code readability, and reduces the likelihood of errors or inconsistencies in URL structure.

FAQ 2: Why should I use dash/hyphen (-) instead of underscore (_) in my URLs?
Answer: Firstly, search engines like Google treat dashes as word separators, making it easier for them to understand the individual words in a URL.

This makes URLs easier to understand and remember, ultimately improving the user experience.
