Website not retaining visitors

I launched a new website last week, and have Adwords attracting the customers to the site – just over 150 so far, but the majority of them only land on the landing page and don’t interact any further with the site.

I have been watching it closely on google analytics on the realtime overview reports, and when a client comes in from adwords, it shows a double page load, then nothing further. I have obviously visited the site a lot myself, and see nothing incorrect with the visuals on my device, and have had a colleague test it from another country, and this is what happened.

when he clicked on the ad, which went to my homepage, all he could see was the top navigation bar, but no content below. he then clicked onto a further page through the nav bar and it showed up fine. when he clicked on home back to the original page, it then loaded fine. I have never seen this, or anyone else that has tried it from my location.

I am wondering whether the people landing on my site are not seeing it as it should show and are just leaving immediately – this is obviously costing me a lot through adwords too.

I have the plugin wp fastest cache installed as i thought it was that the pages were loading very slow, but they’re relatively quick now.

my website is http://www.allsaw-online.com

I’d be very glad if someone could advise on what the issue may be.
