Visual Composer

When I use visual composer in a blog post, a preview of an excerpt of the post does not appear on the blog page. Also, I am using the WordPress SEO plugin and it does not recognize any of the text or images embedded into the post by visual composer. I’m not sure if this is an issue with the High End Theme or Visual Composer. Also, the most important part of building a website is SEO! I’m not sure you if you guys have ran into any problems similar to this one, but when I asked about an alternative ad displaying solution, I was told to use the Revolution Slider. That isn’t designed for ads and I would appreciate a bit more professionalism when getting a response for my answers. I purchased this theme, I love it, but let’s be realistic. It can’t do everything. Please, if you could, point me in the right direction. If not, I’ll go look for help else where. Thanks!
