Why Keyword Surveys Are Important:

Keyword research is one of the most important parts of SEO. That’s because it helps people decide what to type in search engines. Without them, other factors like page optimization, SEO-friendly content related to SEO, etc. cannot be achieved. Keyword research is the fundamental foundation of SEO.

Imagine trying to write on any topic. The first thing you always want to understand is what your viewer really wants to read and how to use it. And which audience will read your article? Hence, this information can be gathered through keyword research.

You can then use it to understand who you are competing with. That means it helps to find out who is showing in which format at the top of the SERP. You can also use keyword research to easily explain whether your keywords are worth targeting.

Finally, it also helps to understand current trends. For example, you can use Google Trends to see when people search for that particular keyword. You can also see how popular it was in five years. Hence, you can use this information to plan your content and develop your marketing strategy.
