Brain nailed it!

Simply put, ask your EXISTING CUSTOMERS how they found you; specifically ask if they searched a particular word/phrase and via what tool. Use www.typeform.com to create a FREE survey for new/existing customers and be willing to offer a discount for time spent helping you with research. Also, use your EXISTING customer base to determine your target audience via a "buyer persona." Creating a "buyer persona" will help you determine what marketing tactic to employ, which could be none, some or all of the marketing tactics already suggested. Creating a "buyer persona" will also help define your ideal or primary customer and the budget you need to reach them.

FYI: On my end, a Google search of "corporate housing" produces a list of search engine optimized sites by city. My top hit is www.corporatehousing.com, which gives visitors a coast-to-coast list of short term, corporate lease options. Find two other sites like it then determine your competitive advantage, your unique selling proposition and your value proposition.

The nature of your business means that you have a ready-made audience; a demographic that's not even on your radar, e.g., major hotel brands, corporate HR departments and real estate agents.

My two cents! Call for “clarity!”
