1.Hyphens (–)

Hyphens are SEO gold for separating words in URLs. Search engines treat them as word dividers, making URLs easier to read and keyword-friendly.

2. Alphanumeric Characters (A-Z, a-z, 0-9)

These characters are universally accepted in SEO. They are the core building blocks for URLs, meta titles, and descriptions.

Example: example.com/top10-seo-tips

3. Underscores (_) (Limited Use)

Underscores work in filenames and some internal systems. However, unlike hyphens, search engines do not treat them as word separators in URLs.

Good (File Name): seo_guide.pdf

Avoid in URLs: example.com/seo_guide

Google treats this as a single word: “seoguide”.

Neutral Characters (Use Cautiously)

1. Periods (.)

Periods are commonly used in file extensions and subdomains.

• Good for File Extensions:
  example.com/guide.pdf
• Good for Subdomains:
  blog.example.com
• Avoid in URLs otherwise: Periods might confuse search engines if used outside their intended roles.

2. Plus Signs (+)

In some systems, the + sign is treated as a space, but its behavior can vary across platforms.

• Caution:
  example.com/seo+tips may work, but using hyphens is safer and more consistent.

Characters to Avoid

These are the characters you should avoid as much as possible using in meta description, meta title and url. This gives a bad user experience, It gives the user a hard to read vibe. Besides, the google bots also find it quite hard to match the data you provided in the blog page if the url is stuff with unnecessary characters.

1. Spaces ( )

Spaces in URLs get encoded as %20, which is unsightly to users and search engines alike.

Bad: example.com/seo tips -> example.com/seo%20tips

Fix: Use hyphens: example.com/seo-tips

2. Special Characters (@, #, $, &, *,%)

Special characters are for specific technical purposes in the URL and can break them or create indexing issues when used improperly.

Bad Examples: & is used in query parameters but is better avoided elsewhere:

example.com/page?category=seo&topic=tips

# creates fragment identifiers but can prevent crawlers from indexing full pages:

example.com/page#section

3. Accented Characters (é, ñ, ü, ç)

While search engines are getting better with accented characters, they still can cause issues, particularly with older systems or when URLs are shared. Besides, using them in titles or URLs can really ruin the user experience. 

Bad: example.com/mañana-seo

Fix: Use unaccented equivalents: example.com/manana-seo

4. Punctuation Marks (!,?, ~,,, :, 😉

These have no business in the URL. They confuse the search engines and users alike. Don’t use them in the URL but you can use them in the title or subtitle of your blog. 

Avoid: example.com/seo-guide?

5. Backslashes (\\) and Brackets ([], {}, ())

Backslashes and brackets are reserved for specific coding contexts and break URLs or mess up renderings when not used well.

URL Encoding and Its Impact on SEO

When non-SEO-friendly characters are used, they often get encoded automatically, which results in cryptic-looking URLs.

example.com/seo tips & tricks -> example.com/seo%20tips%20%26%20tricks

While functional, encoded URLs reduce readability and can look untrustworthy.
