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.
If your social media profiles contain a link to your website, then you’ve turned your engagement into another channel for website traffic. Just be sure to engage moderately and in a sincere way, and avoid including links to your website in your comments—lest you appear spammy and hurt your online and business reputation. Increased traffic should not be the goal of your engagement, but rather a secondary result.
So I’m not good at English. Well I’m running a new vacation rental and travel website in French. But it seems that in francophone area people are reluctant to implement backlinks. I do need links to rank because I have strong competitors. So I’ve decided to ask for those links to Anglophone website owner. Since my content is in French, I thought I could ask for links to pages with solely touristic spots photos. What do you thinks of that?
Really its just a matter of getting creative - grab a cup of caffeine and think for a minute about what resources you have to try to get some insight on your visitors (or target markets) and their needs before you dive in.  Think about how much time it might take you (or what the cost of the reports would be if you are going to buy some market research reports), and tack that onto your billing as an optional service.

Another example when the “nofollow" attribute can come handy are widget links. If you are using a third party's widget to enrich the experience of your site and engage users, check if it contains any links that you did not intend to place on your site along with the widget. Some widgets may add links to your site which are not your editorial choice and contain anchor text that you as a webmaster may not control. If removing such unwanted links from the widget is not possible, you can always disable them with “nofollow" attribute. If you create a widget for functionality or content that you provide, make sure to include the nofollow on links in the default code snippet.

By relying so much on factors such as keyword density which were exclusively within a webmaster's control, early search engines suffered from abuse and ranking manipulation. To provide better results to their users, search engines had to adapt to ensure their results pages showed the most relevant search results, rather than unrelated pages stuffed with numerous keywords by unscrupulous webmasters. This meant moving away from heavy reliance on term density to a more holistic process for scoring semantic signals.[13] Since the success and popularity of a search engine is determined by its ability to produce the most relevant results to any given search, poor quality or irrelevant search results could lead users to find other search sources. Search engines responded by developing more complex ranking algorithms, taking into account additional factors that were more difficult for webmasters to manipulate. In 2005, an annual conference, AIRWeb (Adversarial Information Retrieval on the Web), was created to bring together practitioners and researchers concerned with search engine optimization and related topics.[14]
When Larry wrote about the kick in the proverbial teeth that eBay took from Google’s Panda update, we managed to secure a link from Ars Technica in the Editor’s Pick section alongside links to The New York Times and National Geographic. Not too shabby – and neither was the resulting spike in referral traffic. Learn what types of links send lots of referral traffic, and how to get them, in this post.
Sending out regular newsletters and promoting offers through email is a great way to stay in touch with your customers and can also help to get traffic to your website. Provide useful information and links to pages on your website where they can learn more, such as through blog posts and landing pages for particular offers. Just make sure that you don`t continually bombard your readers with emails or your customers will either disengage with, delete, or unsubscribe from your emails.
