How to create SEO-friendly URLs

An SEO-friendly URL is short, readable and describes the page in plain words, such as https://www.example.in/courses/data-science-pune. Use lowercase letters, separate words with hyphens, avoid long parameter strings, serve the whole site on one hostname, and never change a URL without a 301 redirect. Good URLs help people trust the link and help Google understand your site's structure.

What makes a URL SEO-friendly?

A URL is SEO-friendly when a person can read it and guess what the page is about before clicking. Google's URL structure guidelines recommend simple, descriptive words rather than long ID numbers.

Should you use hyphens or underscores?

Use hyphens. Google recommends hyphens to separate words in URLs, because underscores can be read as joining words together, so neet_coaching may not be read as two words.

Do not use spaces either; they turn into %20 and look broken when shared.

Do URLs need to be lowercase?

Yes, use lowercase throughout. URL paths are case-sensitive, so /Courses and /courses can be treated as two different pages, which splits signals and creates duplicates.

If your server serves both, pick lowercase and 301-redirect the uppercase versions to it.

How long should a URL be?

Keep URLs as short as you can while still describing the page. There is no fixed character limit for ranking, but short URLs are easier to read, share and remember.

Practical rules:

• Two or three folders deep is usually enough, for example /courses/mba/delhi.
• Remove filler words such as "and", "the" or "page" when the meaning stays clear.
• Leave out dates unless the content is truly date-specific, so you can update a page without changing its URL.
• Include the main topic or keyword once, naturally. Do not repeat it.

Why should you avoid URL parameters?

Parameters such as ?sort=price&color=blue can create thousands of near-duplicate URLs for the same content. That wastes crawl effort and splits signals across copies.

Use parameters only where they are genuinely needed, such as filters and search results. Keep the clean version as the canonical URL, link internally to clean URLs, and never use tracking parameters such as utm_source in internal links.

Should you use www or non-www?

Either works for SEO; what matters is choosing one and sending the other to it with a 301 redirect. If example.in and www.example.in both show the same site, search engines see two copies.

Check all four combinations. Each should end on your one preferred version:

http://example.in        -> https://www.example.in/
http://www.example.in    -> https://www.example.in/
https://example.in       -> https://www.example.in/
https://www.example.in   -> 200 OK

Make sure the other hostname still resolves in DNS. If it does not, visitors who type it get an error instead of a redirect. Then use the preferred version in canonical tags, your sitemap and internal links.

Can you change URLs on an existing site?

You can, but only with a 301 redirect from every old URL to its new equivalent. Without redirects, the old URL returns 404, you lose the links pointing to it, and the page may drop out of search for a while.

Only change URLs for a clear benefit, such as fixing a truly confusing structure. Do not change them just to add a keyword. If you are changing many URLs at once, follow the site migration guide, and update internal links so they point straight to the new URLs, not through redirects.

Common mistakes

• Uppercase letters and underscores in URLs.
• Session IDs or tracking codes in internal links.
• Both www and non-www versions serving the same pages.
• Changing URLs during a redesign without redirects.
• Very long URLs built from the full page title.
• Non-English characters without checking how they display when shared.

How do you check URLs with Spider?

Spider's page audit flags URLs that are over 100 characters, contain uppercase letters, underscores, spaces or query parameters, or sit more than four folders deep. It also checks whether the www and non-www versions redirect to one hostname. A site crawl finds redirect chains and broken links across the site after URL changes.
