What makes a good slug
Short, readable, and made of the words someone would actually search. "how-to-do-an-seo-audit" tells a reader what they are about to open; "post-4471" tells them nothing, and neither does a slug carrying the entire headline including its subtitle.
The URL appears in search results, in shared links, in WhatsApp messages and occasionally in print. It is read by people more often than most people assume, and a long one gets truncated in results and mangled when pasted.
Three to five meaningful words is the range worth aiming for. Dropping filler — a, the, of, and — usually gets you there without losing anything, which is what the option here does.
Hindi, Marathi and the empty-slug problem
Most slug tools handle non-Latin text by normalising accents and stripping what remains. That works for café → cafe and fails completely for Devanagari, where nothing survives — you get an empty slug, or a URL of percent-encoded bytes that is unreadable everywhere it appears.
Devanagari is an abugida rather than an alphabet: each consonant carries an inherent "a" that a vowel sign replaces and a virama removes. Transliterating it correctly means walking the string and resolving those marks, not deleting them. That is what happens here, so क्रिकेट समाचार becomes kriket-samachar.
You can use Devanagari directly in a URL — modern browsers support it and Google handles it. A Latin slug is still usually the better choice, because it survives being pasted into WhatsApp, email, an SMS and a printed flyer without turning into %E0%A4 sequences.
Changing a slug that is already live
A published URL is an address other people have linked to and Google has indexed. Changing it without a redirect turns every one of those links into a 404 and throws away whatever ranking the page had built.
If the page is live, set up a 301 redirect from the old URL to the new one first, then change the slug. WordPress does this automatically when you edit a published post's slug; most other systems do not, and hand-rolled sites almost never do.
Which raises the question worth asking before you change anything: is the new slug enough better to be worth the risk? Usually the honest answer for an established page is no. Get it right on new pages, and leave old ones alone unless the URL is genuinely misleading.
