alothough I am a newbie taught by Morgan et al , if you are targeting whey protein - it's not even in the text on the page.

Probably G* doesnt even know what the page is about.

You'll need these in your header tags and maybe some bold.

On your alt tag for your image put some of your KWs in - not myprotein.co.uk as people are not searching for that.

And of course backlinks, I havent even checked , but get people linking to you with the anchor text in the link that you are targeting and your page is about.
