I think a bit of stats would go well with this poll. People may have a favourite in the list, or may criticize the poll itself, but the truth is woothemes is now leader in this business niche, far in front of all the other. Another thing is the websites in this poll clearly do not play on the same level. A quick look at google trends gives us a bit more insight on the figures. I started by selecting the poll websites, then I kept only the ones actually appearing in Google trends.

First conclusion: Woo! Woothemes is defintely above. Not so surprising though, Adii keeps transparency in his business, and his marketing methods are far more developed than any of the other market places. The number of people behind woothemes also makes a difference; a one-man company often makes less noise. Then imho, the brand Adii has built around himself also helps him selling: after all, isn't he the "WordPress Rockstar"? Who in the WordPress community has got so famous? Small Potato is the first name that comes to my mind (and God knows they loved each other ;) )

I think that may be a key point for marketing your brand: you got to market yourself as well:

Let's have a look at elegantthemes.com for instance (I am not even a user of their themes, its just the perfect example here): their theme club is maybe the cheapest on the market right now, for a big amount of good quality themes, however Jeff did not include it in its poll, however the website stats are bigger than many websites quoted here: big proof the company needs to get more coverage! Then lets look at the owner... Who knows his name? Even on elegantthemes's blog, he is "admin". A quick look through the terms and conditions on the site tells me he is Nicholas Roach. I was not able to find more info about him.

No personal blog, no twitter account... Or they are well hidden, or not good enough for Google!
No big advertisement, a few affiliate links, a few articles and giveaways on design blogs such as noupe, and most of all, not too much activity or comments on WordPress blogosphere...
That's a sign for a potential customer, don't you think?

Don't you think that could be the beginning of a recipe for a good brand advertising? Don't you think that's what makes the difference between all these websites? In the end, shouldn't we all follow the advices Adii gives on his own blog about brand advertising? You may or may not like the man and his methods, but they seem to work pretty well, he wins everything so far :)

Sorry for the long post :)
