What is your site visitors’ screen resolution? With an increase in sales for netbooks and laptops, your site might be experiencing an increase in site visitors with smaller screen resolutions.

I hope you don’t underestimate the impact of screen resolutions to the conversion rate. I have seen many sites where the call to actions or the important messages are under the fold.

Notice that height with 768 ranks second for this one site. (I have seen 1024×768 rank first for some sites)

Here is an example of a CPG site. Perhaps selling is not their main goal, but they have a call to action “Buy Online”, so let’s assume that is their main site objective for this case.

Notice that the red box (call to action) goes away when I changed my resolution to 1024×768. They are increasing the chance for visitors to bounce, because it makes the gap between the customer intent and that landing page’s objective to widen.

I have seen cart add ratio decrease tremendously when call to action to buy is under the fold for specific screen resolution. I guess it’s time to review your screen resolution and make sure that the drop off is minimize by a simple redesign.

I would also have to mention that not only people adjust their screen resolution differently, but browsers can also allow users to set different zoom percentage. That also affects your site’s performance, but at this point, it is probably wise to test and find out. Good luck!!
