I've noticed your Pagerank is low and your Alexa isn't great, so how can you make such bold claims about your website?

Pagerank is not an indicator of traffic, our traffic is highly targeted and comes through social media and paid advertising and thus Pagerank is largely irrelevant. Alexa isn't the most reliable ranking tool however our UK Alexa rank, given that we have only begun targeting brides and grooms three months ago, is exceptional (29,000 and falling each day).
