When it comes to SEO content is king. Not just any content will do though. You need to have the right content pertinent to your business and marketing efforts and you need to ensure that content is filled with keywords in the right places.
Visits are definitely important for your website, but it is not the most important measurement for success. If you have a million views in a month, but those views don’t result in an increase in business, well then those views haven’t amounted to much. That’s great that search results are resulting in traffic for your website, but you want to convert those visitors to customers/clients.
