Frequently Asked Questions

What is a URL slug?

A URL slug is the human-readable part of a web address that comes after the domain name — for example, in https://appstechy.com/seo-tools, the slug is seo-tools. Slugs are used by search engines and users to understand what a page is about before even clicking on it, making them a key on-page SEO element.

Why is a clean URL slug important for SEO?

A clean, keyword-rich URL slug helps search engines quickly understand your page's topic, which can improve indexing and ranking. Short, descriptive slugs also look more trustworthy to users in search results and social media shares, which improves click-through rates. Google officially recommends using simple, readable URLs in its SEO guidelines.

Should I use hyphens or underscores in a URL slug?

Always use hyphens (-) to separate words in a URL slug. Google treats hyphens as word separators, so "seo-tools" is read as two separate words "seo" and "tools". Underscores (_) are treated as word joiners, meaning "seo_tools" is read as a single word "seotools", which can hurt your keyword targeting.

How long should a URL slug be for SEO?

Keep URL slugs as short as possible while still being descriptive — ideally 3 to 5 words. Remove stop words (a, the, and, of, etc.) to keep the slug concise. For example, instead of "how-to-improve-your-website-seo-in-2025", use "improve-website-seo". Shorter URLs are easier to remember, share, and appear less intimidating in search results.

Should I include keywords in my URL slug?

Yes — including your primary target keyword in the URL slug is a confirmed on-page SEO best practice. It signals relevance to search engines and users alike. However, avoid keyword stuffing — use only the most important keyword naturally, rather than cramming multiple keywords into the URL.

What characters should be avoided in a URL slug?

Avoid spaces (use hyphens instead), special characters such as !, @, #, $, %, &, *, (, ), and uppercase letters. These can cause URL encoding issues, appear as %20 or other escaped characters, and look messy in browser address bars. Our Slug Generator automatically removes all invalid characters and converts spaces to your chosen separator.

Can changing a URL slug hurt my SEO?

Yes, changing an existing slug can cause a drop in rankings if not handled properly, because existing backlinks and Google's index will point to the old URL. If you must change a slug, always set up a 301 redirect from the old URL to the new one. This passes the ranking authority to the new URL and prevents 404 errors.

Does a URL slug affect click-through rate (CTR)?

Yes. A clean, readable URL slug that contains keywords improves CTR in Google search results because users can see what the page is about before clicking. Studies show that URLs with keywords in them receive higher CTR compared to URLs with random numbers or parameters, which can look untrustworthy.
