Having read a few of Brian's tactics, I'm suspicious as to whether or not he submitted this question himself! :)

But no, this guide is not enough. This is a *tactic* that can be useful for earning links, but it is not a silver bullet solution. Link building is one of the most creative aspects of SEO and a good SEO should use a number of different tactics to earn high quality links.

If you'd like to see a list a link building tactics, I recommend reading Jon Cooper's guide here: pointblankseo.com/link-building-strategies.

Further, when determining quality, I recommend you consider not just the prorietary "SEO value" of the link (e.g. Domain Authority, TrustFlow, etc.) but also the topical relevancy and authority of the site (i.e. what is the site you're hoping to earn a link from actually about?).

Hope this helps!
