Make it as easy as possible for users to go from general content to the more specific content they want on your site. Add navigation pages when it makes sense and effectively work these into your internal link structure. Make sure all of the pages on your site are reachable through links, and that they don't require an internal "search" functionality to be found. Link to related pages, where appropriate, to allow users to discover similar content.
Add relevant links back to your site. Throughout your answer, sprinkle a few relevant links back to your website. The more relevant they are to the question, the more clicks and traffic they will generate. You can also finish your answers with a link to your lead magnet, concluding with something like this: “Want to know more about how to start a business? Check out my free checklist with 10 steps for starting your first business!” and a link to the lead magnet (in this example, the checklist).
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.
You probably visit at least a few sites that are relevant to your business on a regular basis, so why not join the conversation? Commenting doesn’t necessarily provide an immediate boost to referral traffic right away, but making a name for yourself by providing insightful, thought-provoking comments on industry blogs and sites is a great way to get your name out there – which can subsequently result in driving more traffic to your own site. Just remember that, as with guest posting, quality and relevance are key – you should be engaging with other people in your niche, not dropping spam links on unrelated websites.
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.
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.
