Spreaking to Walt Mossberg at AllThingsD’s D9 event, Costolo said that Twitter was a “remarkably successful business” that currently has over 80% of its advertisers choosing to renew their campaigns on the service. Referring again to Twitter ads as “orders of magnitude higher” than traditional web adverts, advertisers including Volvo have seen 50% engagement rates via one advert on the Twitter website.

Radio Shack are reported to have upped their instore exchanges and purchases by double digits from the day before they ran an advert on Twitter, keeping the campaign exclusive to Twitter users.

The overall numbers for 2010 were impressive, with total online ad revenues reaching $26 billion. Search made up 46 percent of that total in 2010, followed by display ads at 38 percent. But display advertising grew twice as fast as search (24 percent growth versus 12 percent), and, today, Karsten Weide of IDC says, display advertising continues to grow faster than search advertising…

…Also of note: Google overtook Yahoo as the leader in display advertising, with 14.7 percent of the market compared to Yahoo’s 12.3 percent share. Microsoft declined to 6.5 percent, while Facebook rose to 8.8 percent, according to Weide.

Here we are: 15 years into our ability to measure the absolute effectiveness of the way and the methods by which we sell something, and, still, TV advertising, which measures nothing, guarantees no sales, offers no data, registers no interest, quantifies no desire, provides no follow-up, and which no sentient being watches anyway, is making more money than ever before.

Waste works.

It makes no sense that television works—and yet, $18 billion says it does

Facebook has introduced a new metric into its advertising dashboard, showing you the amount of people that saw your ad. While Facebook previously showed you impressions on an ad, this counted the total number of impressions. i.e. 1 person seeing your ad 10 times would count as 10 impressions.

Now through the ‘Reach’ metric (viewable on the summary diagram at the top of your Page, and the full reports below), you can see the number of individuals that saw your ad. This gives you an accurate view of the total reach of your ad, and the audience size you’ve reached purely through a branding perspective, not necessarily for who clicked on your ad

The most important aspect of a restaurant Groupon is probably that it’s local. Before Groupon came along, there was no effective way for merchants to reach consumers in their area, while excluding everybody else. If you’re a neighborhood restaurant, you don’t want to entice people who live miles away: you want to reach locals. And while Groupon isn’t quite there yet — especially in New York, where a restaurant more than a few blocks away can feel like a schlep — it’s orders of magnitude better at targeting than anything which came before it. And it’s improving every day.
