Once your website is published, it is searchable, however additional action may be required on your side to ensure your site is being ranked higher based on "keywords".
Keyword research is one of the most important, valuable, and high return activities in the search marketing field. Understanding which websites already rank for your keyword gives you valuable insight into the competition, and also how hard it will be to rank for the given term.
Where does one get all of this knowledge about keyword demand and keyword referrals? From research sources like these listed here:
- Google Adwords’ Keyword Tool
- Google Insights for Search
- Google Trends Keyword Demand Prediction
- Microsoft Advertising Intelligence
- Wordtracker’s Free Basic Keyword Demand
Google's AdWords Keyword tool is a common starting point for SEO keyword research. It not only suggests keywords and provides estimated search volume, but also predicts the cost of running paid campaigns for these terms.
