I have a one-page sales copy which I'm ranking in the search engines, but lately no matter how much work I'm putting into it, it's slowly dropping off the results for my main keywords. I'm wondering if there are any thoughts on if I should make my static HTML sales copy into a WordPress theme. Will this help my SEO seeing as Google loves WordPress? If it won't make much difference because it's only really one page then I wont worry about the investment, but if it could make a significant difference I will definitely move down this track and make the change. Also, I know people will follow up saying put blog on my domain, I have tried this and it definitely helped with my rankings, but it also significantly reduced my conversions because the blog was out ranking my sales copy page (index.html) and it wasn't working well in converting traffic. So I am not interested in this, just the conversion of my sales page in WordPress. Appreciate any feedback.
