URL structure

URL structure is a ranking factor on the margin and a major factor for user trust and CTR. Bad URLs don't doom you, but good ones compound over time.

The principles

1. Short

Shorter URLs tend to rank better. Studies have shown correlation between shorter URLs and higher rankings. Target: under 60 characters.

2. Descriptive

URL should communicate what the page is about. /blog/best-crm-for-insurance is better than /p=12345.

3. Include the primary keyword

When natural. Don't force it if the URL reads weird.

4. Use hyphens, not underscores

Google treats hyphens as word separators; underscores are concatenators. insurance-crm is two words; insurance_crm is read as one.

5. Lowercase only

Capitalization causes duplicate-URL issues on some servers.

6. Avoid stop words only when it improves clarity

"The," "a," "of" can be dropped for brevity, but don't sacrifice readability: /guide-to-crm beats /guide-crm.

Category folders vs flat URLs

Flat URLs

/best-crm-for-insurance

Pros: shorter, no hierarchy to maintain, every page treated equal.

Cons: no signal to Google about site topic clusters, harder to see site structure from URL alone.

Folder structure

/blog/crm/best-crm-for-insurance

Pros: communicates hierarchy, supports topical clustering, cleaner analytics.

Cons: longer URLs, must maintain consistency.

Which to choose

For blogs: use /blog/ prefix minimum. For deep content sites: full folder hierarchy signals topical authority. For simple sites: flat is fine.

Changing URLs: when to do it

Rarely. URL changes require 301 redirects, invalidate some backlinks, and temporarily dip rankings. Only change URLs when:

• Site-wide restructure with clear SEO benefit
• Migrating domains
• URL is demonstrably harmful (spammy pattern, query strings, exposed IDs)

Otherwise: leave URLs alone. Fix the content instead.

Parameters and query strings

Where possible, prefer clean URLs over ?utm_source=...&page=2-style parameters. For analytics, parameters are fine but consider:

• Canonical tags pointing to the clean version
• Parameter handling in Search Console (though Google mostly figures this out now)
