When SEOmoz started running banner ads in July of 2005, we had about 400-500 unique visitors per day. Now, we're well over 1500 uniques each day (and that's over the holidays), and yet, I've only had a single advertiser interested in buying the new blog format ads.

I'm not considering switching back to the old format (I don't think it was valuable for visitors or advertisers), but I am interested to note how averse to risk advertisers appear to be. With attention from Newsweek, Slashdot and the SEO community, SEOmoz is a very focused and comparitively inexpensive way to buy targeted traffic interested in the SEOs of the world, so why the lack of advertisers?

Chalk it up to the new format. Whereas advertisers were willing to pay ~$400-$500 a month to be listed on the side of blog and articles pages, they're less eager to try a new format like the blog ads because it's unfamiliar territory. I'm guessing that this applies not only to SEOmoz, but to the Internet advertising field as a whole, hence the popularity of AdSense, AdWords, Overture and the DoubleClick ad system.

I'm lucky to be among the few who can defy the norm and reject revenue from the site entirely. Many bloggers and site owners don't have that option and must rely on the revenue choices given them. Is it any wonder that paid link advertising has such a hard time getting off the ground? Or that editorial-style ads (advertorials) haven't become mainstream?

What do you think? Do your experiences mirror these, or do you think adoption is moving at a faster pace? Where do you think web ads can go from here?

ADDED: Just found this - IHT's Advertising Supplements - which fit in with the idea of advertorials, but rely on the print version and doesn't link out... Worth a look, though.
