Answer on @Quora by @studiumcirclus to What is the single best piece of SEO advice?
Answer by James Allen:
Easy. Throughout your time dealing with SEO, you'll here many fad-phrases. For example "Link building is dead!" or "Content is king!".
The only thing you need to focus on is "Value-Add". If you build a link, how does following that link add value for the user? If you write content – what value does it add for the reader (informative/educational/entertaining)?
With SEO, don't take shortcuts. Put the work in, focus on Value Add. If you never learn anything else about SEO, learn this.
