OK, so if I move all non essential items from the left onto the right, that will help with search engines,Therefore all that is on the left are categories, and my keyword text, also if I have some sort of small intro on left with H1 and H2 tags this will also help?

I wouldn't compromise the look and functionality of your store simply for the minimal boost in SEO that moving the code slightly up the page will provide. You are still going to have all that JS up top anyway.

Plus, the left hand column is the natural place people look for navigation, moving everthing to the right may end up ticking off your customers :)

That's true, thanks v much for the advice.

If you really want a big boost in SEO, here's the solution:

Also, you have some html code in your title tag...you'll want to get rid of that.

Thanks for advice, I really want to get the search friendly url mod but it only works for 4x and i'm still on 3x. Also what html do I have on the title tag?

You've got a in there.
