Slug Best Practices
Use hyphens to separate words
Google explicitly recommends using hyphens (-) rather than the bottom line (_) as a single character separator. Hyphens are considered word boundaries, while underscores are not considered separators, which may affect search engines' recognition of keywords.
Keep it simple but descriptive
The ideal slug length is approx. 3 to 5 words(approximately 30-50 characters). A slug that is too short may not fully describe the content, and a slug that is too long may be truncated by search results. Remove stop words (such as "and", "the", "a", "of") and keep only the core keywords.
Use all lowercase letters
Although HTTP URLs are theoretically case-sensitive, in practice web servers may handle case differently. To avoid confusion with 404 errors, the Slug shouldAlways use lowercase letters。
Use only letters, numbers and hyphens
Slug should contain only the following characters:
- lowercase letters：a-z
- numbers:0-9 (if necessary)
- hyphen:- (as single character separator)
Avoid using special symbols (! @ # $ % ^ & *), spaces, Chinese or other non-ASCII characters.
Avoid dates and numeric IDs
Try to avoid using specific dates in your slug (e.g. /blog/2024-01-15-post) or a numeric ID (e.g. /product/12345) unless necessary. This information will make the slug look unprofessional, and date-based slugs will make the content look like "old news."
Keep URL structure flat
URL structures should not be too deep. Ideally, content should be located 1-2 directory levels behind the domain, e.g. /category/slug rather than /a/b/c/d/e/slug. A flat URL structure is easier for search engine crawlers to index and is also friendlier to users.
Avoid keyword stuffing
Don’t repeat the same or similar keywords in your slug. For example /seo-tips-seo-guide-seo-strategy Just typicalKeyword Stuffing, which may be viewed as spam by search engines and have a negative impact on SEO.
📌 Golden Rule: When writing a Slug, ask yourself, "Can this Slug allow users to understand the content of the page at a glance?" If the answer is yes, then this Slug is most likely SEO friendly.
