One more media sharing method is to create a presentation and upload it on slideshow sharing sites. Start with a PowerPoint presentation that showcases the tools/techniques on how to solve niche-related problems, offers useful tips or advice, presents a useful Guide or To-Do list, etc.
Create profiles on slideshow sharing sites (SlideShare, Slideboom, etc.); add your website link to your profiles and upload the presentation. Do not forget to tweet about your new uploads and share them via social media bookmarking sites.
