Most companies will have a web presence, but keep in mind that many will have both a "public" web site (such as an e-commerce site) and a corporate web site (for investors).
What kinds of documents are you after? You want to answer the 5Ws (who, what, where, when, why) so that you can better understand the company / brand / product that you selected for your assignment.
- Start with the section that says "Our Company" or "About Us".
- Look for a description of the company's vision, mission, and values.
- Look for a history of the company, which may include a timeline of key events.
- Look for a link that says "News" or "For the Media".
- Look for press releases or official statements (e.g. written documents, audio recordings, podcasts, webcasts, or transcribed speeches, or corporate videos).
- Note: corporate videos, including TV commercials, may be also archived on YouTube or another type of site.
- If the company is publicly traded, then it will often post annual reports and financial statements online in a section labeled "Investor Relations" or "For Investors". Canadian public companies annual reports are also available on the SEDAR web site. US company annual reports are available on the SEC's EDGAR web site.
- You may need to use the company web site's Site Map to find some of this information, which is typically linked at the header or footer of the home page.
