Any elements, colors, fonts etc. used in my concepts could be updated upon your feedback. I've missed the slogan in some designs in purpose but I can get it there if needed.
I've designed a serie of similar concepts using the same font type and colors but concentrating in the simplicity of the mark. In the instances #18, #19 and #20 I've used the arrow at the end of the uppercased N letter as a visual representation of the success (if you wish upper positioned search listings). #21 uses a desktop-like icon as part of the whole composition. In entry #17 and #19 I used the flash-light as a visual representation of the search-find or in your case search-be seen process.
I revised the chosen logo in three slightly different color combinations of blues and greens that are close to the color scheme of www.directorycentral.com You can see them in #42, #43, #44 and in #45 I've given an example of how the logo could be done with some minor light effects.
Please note that what you see as colors aren't exactly the same due to the additional image compression, which happens when the designs are uploaded to this logo tournament website.
Of course, I still can provide you with other color combinations if needed.
