the big deal? A few ads get blocked, so what?
based on a few informed conversations of late I think we are approaching the
5-8% range for consumers using ad-blockers. This starts to really count at that
are three key reasons why this is important:
- Missing impressions — the way
the ad blocker works is that is does not render the ad in the browser. However, the ad was served by the ad server, content management system (CMS)
or image directory. If you are selling or buying impressions this means
you are either cheating or getting cheated. At 5% I think this starts to matter to the advertising buyer.
- Many eCommerce sites use the same directories, or servers serving the ads, to serve merchandizing (or worse) instructional and service content. Often this is done to leverage
targeting capabilities available in the ad server, not available on the legacy commerce platform.** This means sites are just plain broken on ad-blockers — either the design looks terrible, or content the customer needs is just plain missing.
- Many eCommerce sites are
looking to monetize their traffic in other ways besides conversions. This is especially true for high-traffic sites. This is bound to increase, and
sites will be more and more impacted by a problematic ad-serving approach.*

- Longer-term, invest in stronger
CMS and segregate ad serving from content serving and targeting. We have
analysts who can help with this.

multiple browsers (Recommended: IE 6, IE 7, Firefox, Safari, and iPhone-Safari)
