#14 - Not what I'm looking for. #15 - Not what I'm looking for. #16 - Not what I'm looking for. #17 - Not what I'm looking for. #18 - Like the boxed SEO and the font. Brain looks too round, plus may look better without black box. #19 - kind of like it, but has too many colors. Like brain in left better. No need for ".com" or tagline. Don't like the "nobrainer" color, maybe because it does no go with the brain colors. I wonder if a progressive blue (from dark to light) for the brain would look good. The stem being darker. #20 - Not what I'm looking for. #21 - Not what I'm looking for. #22 - Not what I'm looking for. #23 - like the last one, but looks a bit heavy - maybe no black in the brain??
I don't think so, the arrow for SEO is commonly used and brain would obviously be there. I can submit more logos if CH has a problem with it.
