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.
All sites have a home or "root" page, which is usually the most frequented page on the site and the starting place of navigation for many visitors. Unless your site has only a handful of pages, you should think about how visitors will go from a general page (your root page) to a page containing more specific content. Do you have enough pages around a specific topic area that it would make sense to create a page describing these related pages (for example, root page -> related topic listing -> specific topic)? Do you have hundreds of different products that need to be classified under multiple category and subcategory pages?
Expertise and authoritativeness of a site increases its quality. Be sure that content on your site is created or edited by people with expertise in the topic. For example, providing expert or experienced sources can help users understand articles’ expertise. Representing well-established consensus in pages on scientific topics is a good practice if such consensus exists.
This content will help you boost your rankings in two primary ways. First, more content means more keywords, and therefore more opportunities for Google to return your site in the search results. Second, the more content you have, the more links you generally accumulate. Plus, having lots of content is great for getting visitors to stay on your site longer. Win-win!
Use LSI keywords, and answer additional questions that users may think of after viewing the content. Simply offering only the content that a user searches for is no longer enough. Pages need to supply additional information a user may be seeking. Providing additional information will help retain the user, and tell search engines that the page’s content is not only answering the search query but providing additional value that other pieces of content may not be.
This is not to say that small businesses can’t show within the top organic results. If your business is located in a less competitive market or industry, like a nail salon in a small town, you have a better chance of ranking high in organic results. Most small businesses find it easiest to rank within local results, though small businesses can also rank high in organic results by investing in search engine optimization efforts.
