Many SEOs mistakenly believe that running A/B tests – simple tests pitting one page against another – is enough to cause a drop in their search engine ranking. It’s a very persistent myth that, no matter how many times its refuted, just never seems to go away.


A/B testing is an incredibly valuable part of marketing – one of the most valuable, in fact, for online marketers. By testing one landing page against another, we can learn which page elements are helpful to us, which aren’t, and which make no difference to our page’s performance.


In short, it’s a very valuable form of testing. Despite its obvious value, however, it’s a relatively feared form of optimization in the SEO community. As A/B testing pits one version of your page against another, many SEOs mistakenly believe that tweaking a page for an A/B test could result in Google indexing their modified page.


This, of course, would result in a change of their indexed page, and a possible drop in their search engine ranking. The reality, however, is that it’s highly unlikely for a test page to be indexed. After all, Google typically crawls high-traffic websites once daily, and low-traffic websites as infrequently as once every week.


Because of this, it’s exceedingly unlikely that Google could catch your website at the one moment where it’s content is being dynamically generated as part of a test. It’s not impossible, per se, but the likelihood of it happening is so low that SEOs really don’t need to worry.


A/B testing is an incredibly valuable form of testing – one that every SEO should be engaged in on a regular basis. For you to ignore it for any reason – SEO superstition aside – could put you several steps behind your competitors.
