I like the direction of #9 and #8. I would prefer the logo stays horizontal like #9, but I like the direction of the symbol in #8 and how the font matches better with the symbol.
Thanks for the feedback. The design is a representation of data blocks organized to form a an organized structure to represent SEO aspect. Also the whole image is the letter M and H
We like where logo #15 is going, we would like to see different fonts (keep the lowercase) with maybe a bi-color for media and holics. Try adding the font on logo #17
Font and color of text is right on, the symbol is in the right direction, but needs to be simpler, maybe flatter? more 2d and drop the drop shadow on the symbol.
