3 instances when you should not be using a .com as a top level domain

  WHEN NOT TO USE.COM AS YOUR TL DOMAIN :Most of web urls have a .com as a TLD, however in some certain circumstances its better to avoid using a .com as a TLD We take a look into a few special cases when we use TLD other than .com

1) When you own the brand .com already and wish to redirect it to a .tv, .org,.biz possibly for marketing, branding and geographic reasons , to venturing into areas across corporate social activity as a CSR initiative. Additionally, any socially relevant service or addressing the bottom of the pyramid either through a corporate initiative or tying up with a NGO.
2.You can use .gov,.mil,.Edu domains if you belong to the similar category ( for the appropriate organizations and associations )
3) When you are serving a specific geography or a market and are completely focussed on “the local market” without the any intention of venturing into other markets for a long time to come. In such cases country extensions are a great way to get good search ranking. ( co.uk, co.in..br,.fr ,.de ) 4) When your organization is non profit and you are into a social cause, like NGO, charity, helping war veterans, collecting donations for social cause. Under these circumstances you can use a .org. extension

The world wide web 's made of of 92% .com domain as the TLD. Though the top level domain hardy matters in terms of search, however the url is an important  part of online branding as well as social media .
