Five to Follow on Twitter for SEOSearch Engine Land's Danny Sullivan offers his top picks for SEO know-how.

From writing content with commonly searched-for phrases to cross linking to other pages, a lot can go into optimizing a business's website for maximum visibility. One person who's familiar with the ins and outs of search engine optimization is Danny Sullivan. A former newspaper journalist, Sullivan in 1997 launched a SEO-focused news site calledSearch Engine Watch, which he sold the following year.

Sullivan left the site in 2006 and co-foundedSearch Engine Landwith executive editor Chris Sherman. As editor-in-chief, he oversees the sites content, which ranges from topics such asSEO, search engine marketing, pay-per-click and social media.

"Business owners all should be thinking about SEO," says Sullivan, who is 46. "It's one of the easiest and most effective ways to attract new customers to your business. If I said to you, 'I'm ready to send you five or six customers that are ready to make purchases,' would you say no to that? Well, that's exactly what SEO can do -- sometimes without much work. Simple changes to a listing in Google Places can impact whether or not a business will get more people finding them."

Sullivan also is active on Twitter, often tweeting for Search Engine Land (@sengineland) and frequently on his personal account (@dannysullivan), which has nearly 125,000 followers. Here, Sullivan identifies his picks for Twitter feeds worth following for insight on SEO.
