In today's online environment where relevant content is especially important, you can shoot yourself in the foot with a policy that prohibits deep linking to your site, especially if you put resources into developing new content. Also, if you happen to be advertising online, say, with a Google AdWords account and you're not leveraging your content development regimen, your SEO isn't, well, optimized.
A three step plan to improve your performance online:
1. Develop relevant content about your market or business, make the content conducive to deep linking and publish it online.
2. Adjust your online ad program to leverage that content.
