Seo is really an integral part of digital marketing. Since the advent of Panda and Hummingbird, LSI is becoming increasingly important in SEO as it’s used by Google to determine between ‘keyword stuffed’ articles and genuinely relevant content. Long-form content is a magnet for long tail searches. The more searchers and visitors you attract, the more you can ‘satisfy’ and the better chance you can rank higher in the long run. Monitoring a wide variety of data sets helps an SEO to spot trends and potential algorithm changes. Backlinks are the foundation of Google's algorithm for determining a site’s page rank.
