Keywords research and analysis are two of the most crucial aspects of SEO (search engine optimization). Targeting the right combination of keywords can help you in driving large amounts of organic search traffic to your blog/site.
It's important not just to target the most searched keywords, but also the long-tail keywords to ensure that your website receives highly targeted traffic.
The Google keyword search tool, SEOToolbook, and WordTracker are three handy keyword research tools that can be used for finding the most profitable keywords for creating fresh content.
However, one must bear in mind that the quality of content must always be given the top priority, as poorly written content targeting niche-specific keywords can never help in getting high SERP rankings.
