I find it interesting that you talked about nutrition supplements for athletes. I am very close to launching such a product for enhancing aerobic exercise performance in women (ie. improved times in a 3 mile run).. The product contains no stimulants or exotic herbs. In fact three of the five ingredients are well known minerals, but in forms not found in most multi-vitamin-mineral supplements. The research behind the product comes from me. The credibility behind the research is that I am a professor of human nutrition with over 100 research papers. Now, the trick will be to use my connections and credibility in a business savvy way.
I consulted a few years ago before Yahoo and CNET and my clients were all small businesses, even friends' sites.  No matter the size of the project, you can still try to get some insight into your target audiences and what they need or want.  I mentioned in a previous comment I used Search once to determine sentiment on a site vs. it's competitors by searching for a feature the site and its competitors all had, along with "like", "love", "hate", "wish", etc.  I also took note of who the people were who said those things and where they were talking (forums, twitter, etc).  It's a hacked manual approach and although not nearly as quality as a good market research report, at least I have a llittle bit of insight before going out to make site recommendations based solely on tags & links.  If you're recommending the site build things that people want (and fix or remove things that they dont), you're more likely to gain links and traffic naturally.

On one specific project, one of the SEOs on my team was brought in during the wireframe stage. T­he entire product team held SEO-specific meetings every week to go over specific recommendations, taking them very seriously, and leaning on every word our team said. We were thrilled. We were hailing their efforts, promising big wins for the relaunch, and even hyping up the launch and it’s projected SEO results in the company SEO newsletter.
Robots.txt is not an appropriate or effective way of blocking sensitive or confidential material. It only instructs well-behaved crawlers that the pages are not for them, but it does not prevent your server from delivering those pages to a browser that requests them. One reason is that search engines could still reference the URLs you block (showing just the URL, no title or snippet) if there happen to be links to those URLs somewhere on the Internet (like referrer logs). Also, non-compliant or rogue search engines that don't acknowledge the Robots Exclusion Standard could disobey the instructions of your robots.txt. Finally, a curious user could examine the directories or subdirectories in your robots.txt file and guess the URL of the content that you don't want seen.
Thanks Brian. I’ve had a “a-ha” moment thanks to you! Great advice. I knew that backlinks would improve the organic SEO rankings to our client-targeted landing pages but I never knew it was through getting influencers to backlink blogs. I always just assumed it was great content that users wanted to share with others. It was driving me mad why people love my content but never share enough. Now I know!
In 2007, Google announced a campaign against paid links that transfer PageRank.[30] On June 15, 2009, Google disclosed that they had taken measures to mitigate the effects of PageRank sculpting by use of the nofollow attribute on links. Matt Cutts, a well-known software engineer at Google, announced that Google Bot would no longer treat any nofollow links, in the same way, to prevent SEO service providers from using nofollow for PageRank sculpting.[31] As a result of this change the usage of nofollow led to evaporation of PageRank. In order to avoid the above, SEO engineers developed alternative techniques that replace nofollowed tags with obfuscated JavaScript and thus permit PageRank sculpting. Additionally several solutions have been suggested that include the usage of iframes, Flash and JavaScript.[32]
Inclusion in Google's search results is free and easy; you don't even need to submit your site to Google. Google is a fully automated search engine that uses web crawlers to explore the web constantly, looking for sites to add to our index. In fact, the vast majority of sites listed in our results aren't manually submitted for inclusion, but found and added automatically when we crawl the web. Learn how Google discovers, crawls, and serves web pages.3
Every website should have a content strategy focused around your top keywords. When you create content such as blog posts, videos, whitepapers, research reports and webinars, it gives people something to link to. In addition, the content you create can rank by itself in the search engines. For example, if you write a blog post on “How to Pick an SEO Company,” there is a possibility it will rank for some of the keywords you use in the title and in the body post, especially if the post gets linked to from other websites or shared a lot on social media. It also helps if your website as a whole already has significant high-quality links.
