The Curious Case of an Ad VS Ad-Free Site

Gone are those days when Google Ad-sense revenue was the primary source of revenue for most of the B2b Portals. This story is about a B2B portal which connects Buyers and Suppliers of scrap & recyclables. Started in 2002 the portal has a subscription based revenue model with a considerable amount of Ad-revenue from Google Ad-sense, Banner Ads. From 2004–2012 the Ad revenue was in the higher range of XXXX $/month contributing to 70% of revenue. 90% of the Ad revenue was from Google Ad-sense.

Even-though the traffic to the portal was increasing, the Ad revenue started decreasing steadily until it reached less than 10% of the revenue in the late 2000’s. With the revenue belly up we worked hard on the subscription model by adding value added services, advanced features coupled with excellent support services. Our subscription revenues grew exponentially, but we still kept those Ad’s running. Recently we had a discussion with a consultant who suggested us to remove all the ads as it was annoying and hurt the user experience.

We had a medium square banner on the top right, a long banner on the left bar, a leader board in the footer and also had suggested content ads. We removed all these ads, making the portal totally ad-free. So with a clean site, we expected the conversion rates to go up but the exactly opposite happened. The conversion rates came down 58% from .09 to .04. The transactions fell 60% from 10 to 4. The bounce rate increased by 3.54%(Would you believe that?). The revenue took a hit by 42.19% from $794 to $459.

What do we learn from this case?

The common perception that an ad-free site performs better than a site with ads have been smashed by our Google Analytics data. Although the data is a bit early to come to a solid conclusion (Seven days before and after the changes) it clearly indicates that relevant ads play a huge role in the psychology of clients.

Traffic Decreased From Developing Nations

One can safely conclude that Google prioritize user experience based on the visitors from different countries and thus showing pages with Ads & without Ads on their SERP’S. In the ecommerce perspective, ads play a significant role in developing countries in determining the conversion rate. With the revenues taking a hit, we have displayed the Ad’s again and if you wish to know the outcome please request for an update.
