Here is a detailed step by step about how you can place Google Adsense ads in between shopify blog post articles and sidebar.
Its big time, shopify allows the merchants to integrate the custom ad codes for various locations like sidebar product, sidebar blog, sidebar contact, sidebar category, blog top, blog middle, blog bottom, etc. Right now, there is no direct method to get this done and you have to have some coding experience to get this done. But there is absolutely no way to automatically show an ad in the middle of a blog article like we do it on WordPress with some plugins.

In order to add your ad code to shopify blog pages or blog articles pages, you have to edit 3 files – article.liquid , blog-template.liquid files.
Here is a screenshot of article.liquid from one our store to show you where exactly you need to place the ad code so that the ad shows on top and bottom of the blog article nicely. You can see it in live action here.
