Adding Presentation and data in Google Scholar
Google Scholar usually (not always) just crawl the contents which are organized like a research article. If it's just a presentation (e.g. powerpoint, LaTeX beamer, poster, etc.) you could upload it in F1000Research or Figshare which could give you a DOI and will be fully citable. But it does not guarantee that it will be indexed by Google Scholar. Also I like Figshare cause you could share your data with presentation/paper/pre-print under Common Creative license (it's not the only license available in the Figshare).
