Two addresses, one site
This site is published at WelcomeToKolkata.in, and every page names that address as its canonical address.
Why there are no direct company links
Every company entry routes through a search rather than to a company site. That keeps the site neutral, keeps entries current without constant editing, and means no business gains or loses an advantage from how it is linked here.
Company, mill, factory and shop names and trademarks belong to their respective owners. Inclusion is for independent discovery only, not endorsement or affiliation.
