Yes, I was talking about organic positions in the serps layout in my answer above.
Google autocomplete suggestions that suggest alternative search terms before your particular phrase comes up might also hurt. As to what can be done, you need to become an authority in your niche, much easier said than done, to rank for a broader range of terms.
It is also not smart to depend on Google for all of your business. That's been discussed many times in this forum... and it's very sad to read the cases of business after business that haven't gotten that message.
Note, btw, that many of the factors that affect your rankings and click-through rate in organic will also affect your click-through rate (and thus your position) in AdWords. These same factors (call them branding or buzz or authority or trust), will also affect your success in the business world in general.
