What might seem somewhat outdated, is still wholly important. Keywords are an important factor of your on page SEO. When people search, they are usually using a few keywords or even a single word. The type of keywords can help search engines find and pick out your content quickly.
I came across a website called Semalt which gives you useful information into your website statistics and tracks your website ranking in Google. In particular, it listed various keywords people had used when they found my forum and listed them in terms of popularity. It is good to see that most common expected terms are the ones that find my forum the most such as ‘animal crossing forums’ but it’s interesting to see some of the more unique searches which link to my forum. Utilising this data I can focus more on the top pages and provide content focused to this.
