Learn how Hacker Safe seal increased sales by 8.83%


A case study presented at MarketingSherpa.com on May 6, 2006, reported a security-logo test performed by Petco, a national pet supply retailer. The test involved varying the placements of the Hacker Safe logo across its website to gauge differences in conversion rate gains. The test outcomes produced the following results: – The logo in the lower left corner of the navigation bar resulted in an 8.15 percent increase in conversions. – The logo below the footer on the lower right increased conversions only 1.76 percent. – The logo on the upper left between the search box and the navigation bar increased conversions 8.83 percent.

And even now, 3 years after the experiment the petco.com website is still has the security logo in their header. So clearly it must work for them very well.


And at proimpact7 we love numbers, so lets see the impact of such improvements in terms of dollars in the examples below. Let’s assume that the site was converting at 5% as an starting point, plus have added the percentage improvement of 1.76% and 8.83%. This will allow you to see what such an increase means, provided the other important site aspects are sorted as well like site usability, site navigation,  structure and professional design etc.
