You must use words from different sources and merge them together. Going back to the example if the three keywords auto-sports and UAE are combined with formula 1 racing, desert derby, stock cars race, Dubai, Sharjah, and Abu Dhabi you will get a whole list of keyword phrases. Using these keyword phrases will positively impact the website ranking on search engines.
Depending on your website you should study your visitors trends by looking at your competitors. See the words and combinations that they are using. After doing this research you can form your own keyword combinations to use.
After the content contained in a website, the second important factor that SEOs have to focus on is link building. If a website has top quality and relevant content and links to credible websites it will rank well on search engines.
