You can confer some of your site's reputation to another site when your site links to it. Sometimes users can take advantage of this by adding links to their own site in your comment sections or message boards. Or sometimes you might mention a site in a negative way and don't want to confer any of your reputation upon it. For example, imagine that you're writing a blog post on the topic of comment spamming and you want to call out a site that recently comment spammed your blog. You want to warn others of the site, so you include the link to it in your content; however, you certainly don't want to give the site some of your reputation from your link. This would be a good time to use nofollow.

Next, consider your audience and the overall mood for your production. Are you targeting a small audience that will appreciate the newest, underground hip-hop track, or do you need something that will appeal to many demographics?

Optimization techniques are highly tuned to the dominant search engines in the target market. The search engines' market shares vary from market to market, as does competition. In 2003, Danny Sullivan stated that Google represented about 75% of all searches. In markets outside the United States, Google's share is often larger, and Google remains the dominant search engine worldwide as of 2007. As of 2006, Google had an 85–90% market share in Germany. While there were hundreds of SEO firms in the US at that time, there were only about five in Germany. As of June 2008, the market share of Google in the UK was close to 90% according to Hitwise. That market share is achieved in a number of countries.
And finally, the other really important bucket is authority. Google wants to show sites that are popular. If they can show the most popular t-shirt seller to people looking to buy t-shirts online, that’s the site they want to show. So you have to convince Google - send them signals that your site is the most popular site for the kind of t-shirts that you sell. Fill this bucket by building a fan base. Build a social network, get people to link to you, get people to share your t-shirt pages on their social network saying ‘I want this!’, get people to comment, leave testimonials, show pictures of themselves wearing the product or using the product, Create a fan-base and then rally them to link to you and talk about you. That’s how you prove to Google that you are trustworthy and authoritative.
