My pleasure Moe.
Rule of thumb that I follow and use/advise clients is:
If you want normal folk, you need to use social media and be active.
If you want businesses (B2B) then get Bing and Google sorted out (website).
One uses their phone while watching TV, on a break at work etc, the other sits in an office (likely using windows and chrome) and uses a desktop computer to search. Either dominate one, or use both to create the right planning.
PS: Businesses spend more and have more money to spend, it's a business decision/budget, they are not looking for the cheapest because it comes out of their shopping or going on budget for the week (moving office? Downsizing? Expanding? you'll find more business uses than I).
