INTRODUCTION
URL chhota technical detail lagta hai, lekin large website par wahi crawl path, analytics label, internal-link target, campaign destination aur long-term content address ban jata hai. Ek inconsistent slug naming rule—kabhi underscore, kabhi spaces encoded as %20, kabhi random IDs—initially harmless lag sakta hai; hundreds of pages ke baad maintenance aur migration risk multiply ho jata hai.
Google Search Central ne 23 October 2026 ko URL structure documentation update ki. Clarification simple hai: words separate karne ke liye hyphens prefer karein, underscores nahi. Google readable, descriptive URLs; standard parameter encoding; logical organisation; and crawlable structures recommend karta hai. Important boundary: this is documentation guidance, not a confirmed ranking-system update.
Indian businesses ke liye sensible response mass URL replacement nahi, future-proof standard banana hai. Existing indexed URLs tabhi badlein jab genuine structural benefit ho and one-to-one redirect, canonical, sitemap, internal-link and analytics transition properly managed ho. WordPress sites, ecommerce stores, directories, publishers aur multilingual properties ke liye ek consistent URL policy aur pre-publication checklist define karein.
WHAT GOOGLE CONFIRMED ON 23 OCTOBER
Hyphens are the preferred word separator
Google’s changelog says the crawlable URL guidance was updated specifically to clarify word separation with hyphens versus underscores. Current URL-structure documentation recommends readable words and shows simple, descriptive examples. A slug such as /digital-marketing-training/ communicates word boundaries more clearly than /digital_marketing_training/ or /digitalmarketingtraining/.
The guidance does not state that every underscore URL will lose rankings. Search systems can crawl many imperfect formats. Recommendation ka purpose consistency, intelligibility and efficient processing hai—not an automatic penalty trigger.
URLs must remain technically crawlable
Google supports URLs defined by IETF standards and says reserved characters should be percent-encoded. It discourages using fragments such as #/product to change page content because Google Search generally does not support URL fragments for that purpose. JavaScript applications should use the History API when content states need indexable URLs.
Use standard parameter encoding
For parameters, Google recommends = between key and value and & between multiple parameters—for example ?category=shoes&sort=price. Non-standard bracket or separator schemes can make crawling and debugging harder. Parameters should exist for a business reason; session IDs, tracking duplicates and endless filters require separate crawl and canonical controls.
A PRACTICAL URL STANDARD FOR INDIAN WEBSITES
1. Use lowercase, descriptive, hyphen-separated slugs
A strong default is /service-name/location/ or /category/product-name/. Keep the core subject visible without stuffing every keyword variation. /seo-consultant-delhi/ is readable; /best-top-affordable-seo-consultant-services-delhi-india-2026/ is promotional noise and ages quickly.
2. Keep hierarchy useful, not decorative
Folders should express real information architecture. A training site may use /courses/google-ads/; a city publisher may use /events/business/; an ecommerce site may use stable product paths independent of temporary campaigns. Do not add /blog/, dates or nested categories unless they help users and content operations.
3. Decide how locations are represented
Local businesses often create city and locality pages. Adopt one convention—such as /services/web-design/rohini/—and apply it only where content and service availability genuinely differ. Thin pages created for every pin code produce maintenance burden and can become doorway-like experiences.
4. Govern Hindi and regional-language slugs
Google recommends using the audience’s language and supports non-ASCII URLs when encoded correctly. Indian teams can choose native-script slugs, transliterated slugs or English slugs. The right answer depends on CMS reliability, sharing behaviour, analytics readability and editorial capability. Do not mix conventions page by page without a documented reason.
For Hindi content, /digital-marketing-course-hindi/ may be operationally easier than a long percent-encoded slug, while a publisher with strong Unicode support may prefer native script. Test social sharing, email, QR codes, server logs, redirects and Search Console reporting before standardising.
5. Remove temporary campaign language from permanent URLs
Festive offers, prices and year labels change. Permanent pages should not require annual redirects merely because the slug says diwali-2026 or 4999-offer. Use dated URLs only for genuinely time-bound news or event archives.
WORDPRESS AND CMS IMPLEMENTATION
Set the rule before publishing
WordPress permalink settings, post-type bases, taxonomy slugs and multilingual plugins can create different patterns. Document the approved structure before editors publish at scale. Prevent automatic duplication such as /category/services/service-name/ when /services/service-name/ already exists.
Control auto-generated slugs
CMS platforms often create a slug from the first headline. Editors later change the title but forget the URL. At pre-publication review, confirm slug length, spelling, word separators, trademark terms, location and permanence. Once a page earns links and traffic, headline changes should not automatically change its URL.
Treat filters and search pages separately
Ecommerce filters can generate thousands of combinations for colour, size, sort order and availability. Decide which combinations deserve indexable landing pages. Others may need canonical consolidation, crawl controls or links that do not create endless discovery paths. Robots.txt alone does not consolidate duplicate signals.
SHOULD EXISTING UNDERSCORE URLS BE CHANGED?
Usually not for the separator alone. If an existing URL is indexed, receives links and serves the correct content, replacing underscore with hyphen creates migration work without guaranteed ranking benefit. The documentation update is not a directive to rename the web.
Consider change when multiple problems combine: confusing legacy hierarchy, duplicate paths, CMS migration, HTTP-to-HTTPS consolidation, domain move, internationalisation redesign or a product taxonomy that no longer reflects the business. Then include separator cleanup inside one planned migration, rather than repeated piecemeal changes.
SAFE URL MIGRATION CHECKLIST
Before launch
Export every current URL from sitemap, analytics, Search Console, CMS and server logs. Create a one-to-one old-to-new map. Preserve pages with backlinks and conversion history. Test whether query parameters, trailing slashes, uppercase variants and HTTP/www versions resolve consistently.
At launch
Deploy server-side 301 redirects directly to final destinations, without chains. Update canonicals, hreflang, structured data URLs, XML sitemaps, navigation, breadcrumbs, image references, campaign links and important external profiles. Ensure new URLs return 200 and old URLs do not create soft 404s.
After launch
Monitor coverage, crawl errors, redirect chains, indexed pages, organic landing sessions and conversions daily for the first week and weekly thereafter. Keep redirects long enough for users, bots and external links to transition. Do not judge a migration only by average ranking; compare page groups and revenue paths.
INDIA-SPECIFIC RISKS
Many Indian SMB websites are rebuilt by a new vendor every few years. Each rebuild can silently change .html endings, WordPress category bases, Hindi transliteration and city folders. Contractually require a redirect map and Search Console handover. “New design live” is not a migration-complete status.
WhatsApp sharing is another practical test. Long encoded URLs can look broken in chat even when technically valid. UPI, QR, SMS and printed collateral also favour stable, concise addresses. A URL standard should work beyond Search.
For marketplaces and directories, seller-entered titles may contain punctuation, multiple languages and duplicate names. Use an immutable record ID behind the scenes, but expose a readable slug and maintain redirect history when names change.

30-DAY IMPLEMENTATION PLAN
Days 1–5: inventory
List patterns by content type, language and platform. Flag underscores, uppercase letters, spaces, IDs, unstable dates, duplicate filters and inconsistent trailing slashes.
Days 6–10: define the standard
Approve separator, lowercase, hierarchy, location, date, parameter and multilingual rules. Include examples for editors and developers.
Days 11–20: fix future publishing
Update CMS defaults, editorial checklist, templates and QA tests. Do not begin mass changes yet. Ensure every new page follows the rule.
Days 21–30: prioritise legacy fixes
Change only high-value structural problems with a verified redirect map. Monitor a small page group first. Scale after crawl, traffic and conversion behaviour remain stable.
CONFIRMED FACTS VS ANALYSIS
Confirmed facts
- Google updated its documentation on 23 October 2026 to clarify hyphens versus underscores.
- Google recommends simple, descriptive URLs and words in the audience’s language.
- Standard parameter encoding uses
=for key-value pairs and&between parameters. - Google generally does not support URL fragments to change page content.
- The changelog describes a documentation clarification, not a ranking-system launch.
Analysis
- Existing underscore URLs should not be mass-migrated only for a speculative ranking gain.
- Indian websites benefit most from a stable publishing standard, multilingual QA and vendor accountability.
- URL changes are migrations with traffic and conversion risk, not cosmetic edits.
- WhatsApp, QR, analytics and campaign usability are valid URL-design considerations alongside crawling.
CONCLUSION
Google’s clarification gives teams a clean default: readable words, hyphen separators, standard parameters and crawlable paths. The strategic lesson is consistency. A good URL survives headline edits, campaign cycles, CMS changes and agency handovers.
Adopt the standard for new pages immediately. Treat legacy changes as measured migrations with redirects, canonicals, sitemaps and monitoring. That approach improves maintainability without chasing an unconfirmed ranking shortcut.
