As I was checking the rankings on Google for my hobby site which is a two word keyword I forgot to include a space in between them making them a single word. I noticed that there is fairly significant difference in rankings when a space is included or excluded I tried in this for a few different phrases and noticed similar results.

Does anyone have any ideas why this happens? Is Google reading this keyword as single keyword somewhere like the title tag, anchor text, or meta?
