A domain name is one of the few website decisions that's genuinely painful to reverse later -- changing it means new business cards, updated ads, lost search rankings during the transition, and confused existing customers. Worth getting right the first time.
Shorter is generally better, but clarity beats brevity if you have to choose. A slightly longer domain that's instantly understandable beats a short one that requires explanation every time you say it aloud.
Avoid hyphens and numbers where possible. Both are common sources of typos and miscommunication -- "shop hyphen name dot com" is awkward to say and easy to mistype, and numbers are ambiguous when spoken ("for" vs "4", "too" vs "2" vs "to").
Match your domain to your actual brand name if you already have one established offline. A mismatch between your signboard name and your website domain creates unnecessary friction for customers trying to find you online.
Consider your .com availability seriously, even if you plan to primarily use a .in or other extension. Many customers will instinctively type .com, and owning it (even just to redirect to your main site) prevents a competitor or unrelated party from acquiring it later.
Finally, check trademark conflicts before committing, particularly if you plan to expand beyond a local market -- a quick search to confirm no established business already uses a very similar name in your industry can save a costly rebrand down the line. Once you've settled on a name that passes all of these checks, register it through a reputable registrar and keep the renewal on auto-pay -- a surprising number of businesses have lost their domain simply by forgetting to renew it.
