Let me tell you a story. Early in my tenure at Yahoo we tried to get into the site dev process in the early stages in order to work SEO into the Product Recommendations Documents (PRD) before wireframing began. But as a fairly new horizontal group not reporting into any of the products, this was often difficult. Nay, damn near impossible. So usually we made friends with the product teams and got in where we could.
If you havent see it already, check out the links in shor's comment below - there are some great resources in there. In some cases you can also consider surveying your current audience or customers through email, on-site surveys or SurveyMonkey.  Be sure to ask for some profiling information that you can use for determining specific persona needs like age, sex, location, etc. (Probably best not to make it sound like a creepy text chat like I just did though...)  :)

On October 17, 2002, SearchKing filed suit in the United States District Court, Western District of Oklahoma, against the search engine Google. SearchKing's claim was that Google's tactics to prevent spamdexing constituted a tortious interference with contractual relations. On May 27, 2003, the court granted Google's motion to dismiss the complaint because SearchKing "failed to state a claim upon which relief may be granted."[68][69]
This philosophy is beautiful in its simplicity, and it serves to correct the “more, more, more” mentality of link building. We only want links from relevant sources. Often, this means that in order to scale our link-building efforts beyond the obvious tactics, we need to create something that deserves links. You have links where it makes sense for you to have links. Simple.
Hi Brian, Awsome content as ever! I’m very interested in your idea of creating an ‘uber’ resource list or expert roundup post i.e. linking out to lots of to other authorities in my niche within one post. But should you always create ‘no-follow’ links to these authority sites to prevent juice from passing to them? And similarly if you sprinkle a few outbound authority links in other posts should they all be ‘no-follow’ or do you think big G ignores ‘no follow’ these days?
On the other hand, I'd like to know how many people constitutes your new experience as an indipedent consultant? Infact, as others noted in the comments here, what you suggest is perfect especially for an in-house SEO situation or in for an Web Marketing Agency with at least 5/8 people working in. Even if all you say is correct and hopefully what everybodies should do, I honestly find quite difficult to dedicate all the amount of time and dedication in order to check all the steps described in your post. Or, at least, I cannot imagine myself doing it for all the clients.
2. Targeted Keyword Discovery: Ideally you’ll want to do keyword research based on what the audience wants, not solely on what content the site already has (or plans to have sans audience targeting), which may be limited. I can do keyword research on health conditions and drugs (content I have on my site) and determine what the general population is searching for and optimize my current content, or I can cast my net wide and look at what my target audience wants first, then do my keyword research. You may find there are needs that your site is not meeting. Knowing my senior audience is interested in primarily in prescription drug plans and cheap blood pressure medication, I can first make sure I’m providing that content, and then further determine the top keywords in these areas (in the next article Step 2), and use those terms in relevant and high visibility areas on my site.

In 1998, two graduate students at Stanford University, Larry Page and Sergey Brin, developed "Backrub", a search engine that relied on a mathematical algorithm to rate the prominence of web pages. The number calculated by the algorithm, PageRank, is a function of the quantity and strength of inbound links.[22] PageRank estimates the likelihood that a given page will be reached by a web user who randomly surfs the web, and follows links from one page to another. In effect, this means that some links are stronger than others, as a higher PageRank page is more likely to be reached by the random web surfer.
When would this be useful? If your site has a blog with public commenting turned on, links within those comments could pass your reputation to pages that you may not be comfortable vouching for. Blog comment areas on pages are highly susceptible to comment spam. Nofollowing these user-added links ensures that you're not giving your page's hard-earned reputation to a spammy site.
I’ve just started blogging and there’s a ton of useful information here. I was wondering how to use reddit and you cleared that up for me, as well as when to post to social media. Quora I’m going to check out as I’ve never heard of them-thank you! In your opinion would you also deal with any of the free traffic generators to have people come and engage, or would you skip that step? Would you use meta tags, and if yes how? Thank you for your time and I look forward to hearing from you!
What is the leadership like? What kind of culture do they cultivate? In smaller companies, the leaders tend to influence the culture. In larger companies, unfortunately, this can get lost. But if you have access to the leadership, spend some time learning about their vision. It should match up to the company's core values, but sometimes there are more gems locked in their minds.
