Off-page SEO is probably the one factor that determines rank the most!
Here is how seo-help123 goes at it, firstly we use Google to find relevant blogs for your content. Next we use Google+ to get you some relevant followers there. Next up we will contact the blog owners and offer a kick ass guest post in return for a link, the next step in our Deviously great plan to get you to rank well is to get the blog posts some crap links (to boost pr) and we will also get you some crap links slowly so it appears natural to Google.
Next we will submit a video you make to a lot of video submission sites! and that way get you both exposure to the video and links, in the end :-)
