Daniel Bianchini gives us 10 stats to justify increasing budgets for search engine optimization projects. He tells us there are two billion people online -- 38 billion in the United Kingdom, and 31 million who actively shop online. Those who operate a niche market potentially already appear on the first page of the search results for the major keywords, which might make marketers think they don't need to invest in SEO. Wrong, Bianchini says. A study by Optify shows the top-ranking Web site has an average click-through rate of 37%, while 60% of the clicks belong to the top three results. Bianchini provides the source of all these good stats, and explains how each helps to build out SEO campaigns.
