You should add to your marketing more info about how you are good in handling traffic and most importantly why. In a way that will make sense with both tech and non tech types. (Non tech has no idea what aws is or a cdn is for example). I've looked at your site a few times (even right now) and that isn't the thing that stuck in my mind from your marketing. The takeaway for me was "expert at WP" not necessarily "expert handling of traffic and here's why". I'm not saying it's not mentioned. I just think that point has to be driven home better.
