It is fairly simple Chandana. Much like marketing yourself offline, you need to establish valuable contacts and relationships within your professional industry. The same goes for the web. Search engines derive authority from links, citations, likes, tweets and any measurable metric they can tally. However, links are still the most important.
Showing Google your companies digital footprint (or web presence) is vast, robust and mentioned on sites they trust will actually make a site with GOOD on-site SEO very powerful. Without that, you'll only see a handful of your pages indexed and served in positions of prominence.
If link building truly is a priority, I would look up Garrett French and read his articles, look at his tools and the Ontolo link building book.
