Richard Baxter discusses whether Web site owners really need large numbers of relevant links to get a site to rank for top keywords. He writes, "No. As long you've built links on reasonably trusted, authoritative domains, and you've thrown in some (sometimes over) optimized anchor text for good measure, you can still rank."
Baxter provides supporting evidence to prove his point with an example. He starts by gathering data from Yahoo Site Explorer and Linkscape. Then he adds the usual metrics, along with an additional series of percentage calculations and counts of inbound link relevancy by profiling links to URLs, titles and domains. He provides graphics and seven takeaways from this example.
