Thanks for asking.
I checked your website and couple of other pages and don't see inline CSS. Usually inline CSS will showup when you enter the CSS under Customize > Setup > Inline CSS. However, you will see page specific CSS and that's because when you design the page layout using Cornerstone and it's element, those changes are specific to that page and Cornerstone automatically creates the underline shortcodes and corresponding CSS.
However, as the goal is to have a better presence on Search engines, I suggest you to take a look at following thread wherein I have shared some inputs and easy to follow but essential principles that will help you have better presence on Search Engines.
