Hey Brian, love your site + content. Really awesome stuff! I have a question about dead link building on Wikipedia. I actually got a “user talk” message from someone moderating a Wikipedia page I replaced a dead link on. They claimed that “Wikipedia uses nofollow tags” so “additions of links to Wikipedia will not alter search engine rankings.” Any thoughts here?
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.

The first relates to internal link structure. I’ve made the mistake you say you’ve seen so often. I have a primary keyword and have used that keyword in the main navigation, linked to a page optimized for that keyword. But I’ve also got a bunch of contextual links in posts pointing to that page, usually with the keyword in the anchor text. I now understand that those internal links aren’t helping much, at least from an SEO perspective. Am I better to remove that keyword and direct link from the menu and simply link the page from multiple posts and pages within the site. Or will I get better results leaving it in the main menu and changing the contextual links in the posts to point to a related page with a different keyword?
Hi Brain, I am a young business owner who has had 4 different websites in the last 2 years but none of them were successful as I would have liked due to lack of SEO. Now I am in process of starting another business and I felt it was time for me to learn about SEO myself. I must say the information you have provided is invaluable and extremely helpful!! I am learning on the go and you are my biggest contributor. Thank you Sir!
Another way to increase traffic to your website is to get listed in free online directories and review sites. For most of these sites, your profile will have a link to your website, so actively updating these listings and getting positive reviews is likely to result in more website traffic. In addition, many directories like Yelp have strong domain authority on Google. There’s a chance that your business’s free Yelp page could rank high for relevant searches.
