I see this on your page
<meta name="keywords" content="<meta name="twitter:card" content="summary_large_image" /><meta name="twitter:site" content="@JamesFulfil" /><meta name="twitter:creator" content="@JamesFulfil" /><meta name="twitter:domain" content="http://www.ecommercefulfilment.com" /><meta name="twitter:title" content="5 reasons customers abandon online shopping carts - and how you can stop them" /><meta name="twitter:description" content="There are many reasons a customer might give up on their order, but there are also plenty of ways you can leverage your eCommerce site and re-marketing tactics to try to change their minds and retain the sale." /><meta name="twitter:image" content="http://www.ecommercefulfilment.com/files/5714/4655/0106/woman-smartphone-girl-technology_card.jpg" />" />
In other words, it looks like you have put all the Twitter meta tags inside a keywords meta tag, when they should be standalone tags that don’t have all their content escaped.
