I got a question on Quora about how to build good links, so I decided to make a video out of the answer. The TL;DW version is you buy them! But how can you tell if a link is good or bad? I take apart moz's 20 factors to show you the 7 that matter for SEO. [video=youtube_share;EbVoKg6BKmU]http://youtu.be/EbVoKg6BKmU[/video] The most important factors for SEO are: Anchor text - exact match is great, but you run the risk of overoptimization filter problems. So change it up with exact match, partial match, semantic terms, URL links, and brand links Relevance - Ideally you want a link from a page that is congruent with your target source Topical Authority of Source - Ideally the linking page should be on a domain that is also congruent with your target site. Domain Authority - The domain you're getting a link from should be strong and trusted. Quality of Page's Other Links - Stay away from bad neighborhoods! Follow vs NoFollow - Follow links are always better/more effective Spam Signals - Stay away from bad neighborhoods! Build your own sites and control your links to control your destiny.
