We’ve tested security and customer service seals countless times in our ten years analyzing eCommerce websites. Here’s a little of what we’ve learned:

Seals are more important if your company or your industry has trust issues.
Seals are more likely to positively impact smaller or lesser known brands. If you’re Amazon or Walmart, seals don’t matter as much.
Certain seals work better than others.

When we say certain seals work better, we don’t just mean building trust in your brand. Seals can also positively impact your SEO — since increased trust in your site can result in longer site visits and lower bounce rates.

The right trust seal can also increase conversions.

In this article, we’ll show you three tests we’ve conducted with Norton and McAfee seals that led to an increase in revenue, and we’ll conclude with recommendations for when and how to use different eCommerce trust seals on your site.
What Are Trust Seals or Trust Badges?

A trust badge is a badge, seal, or emblem that a company displays on their website to make the site feel trustworthy, illicit credibility, or a feeling of security from their visitors or customers, as it indicates the presence of identity protection. Typically, these badges are granted from security companies such as McAfee, Norton, TRUSTe or from business rating organizations such as Better Business Bureau.

Logos from companies like PayPal or Verisign, or even simple SSL certificates may also loosely be considered trust badges since they can evoke trust from potential customers at the time of entering their credit card information. From a business standpoint, the website is calculating that the trust gained from the secure certification helps more visitors convert into buyers.
Trust Badge Research: Our Recent Tests and Why We Tested McAfee and Norton

We’ve researched numerous trust seals in our work (McAfee, Norton, BBB, etc.) via AB tests.

Through our testing, we’ve consistently found:, TrustGuard, and Trustwave seals can actually lower conversion rates
GeoTrust and BizRate seals tend not to impact conversions one way or another
BBB, Norton, and McAfee trust seals are the most likely to increase conversions

Norton Security (powered by Symantec) and McAfee are trusted and well-recognized brands in the online security market. Similarly, BBB is the biggest brand in customer service ratings and has a huge trust factor.

Other security brands, such as, Trust Guard and Trustwave, are cheaper (and sometimes even free with hosting), and they tend to be associated with less professional sites. This association, in turn, decreases the trust of other sites that use them.

We’ve learned from our research that the McAfee trust badge—at the moment—is the most likely to increase conversions and the one we use most on client sites. As you’ll see from our recent tests, in all cases, conversions improved with the McAfee seal and decreased without it.

Will You See These Results if You Add a Trust Badge like McAfee SECURE to Your Site?

The tests detailed above are common in our experience, which is why adding a McAfee SECURE seal to our clients’ websites is often one of the first things we often test in our conversion optimization process.

We suspect if you add a McAfee SECURE badge to your site, you’ll see a noticeable bump in conversions and revenue, because it almost always goes that way for our clients.

With that said, nothing in CRO is universal, and every site is unique. Our advice is that every eCommerce site should at least try adding a secure trustmark like McAfee SECURE and see what happens.
How to Test Trust Badges

We always advocate for testing the results we report (or anyone else reports) for yourself so you can see if it works on your site, especially if you’re considering a trust badge or security seal not discussed in this article. You could even test specific badges related to your industry.

The right placement makes a difference and should be tested. Raising questions about the security of someone’s money and identity while a customer is making a decision about a product may derail their willingness to buy online or simply at that moment from your site.
