Why Keyword Research is Important

Keyword research is the cornerstone of any successful SEO strategy. It helps you understand what your audience is searching for, allowing you to tailor your content to their needs. By targeting the right keywords, you can attract more traffic to your site, increase your visibility on search engines, and ultimately, boost your conversions.


Main elements of Keyword Research

Keyword research isn’t just about finding a bunch of relevant words and phrases. It involves:

1. Identifying Relevant Topics

Start by brainstorming broad topics that are relevant to your business or industry.

2. Finding Keywords

Once you have your topics, you can start finding keywords related to them. These can be short-tail (one to two words) or long-tail (three or more words) keywords.

3. Analysing Keyword Difficulty

This refers to how hard it would be to rank for a particular keyword. It’s usually a good idea to target keywords with low competition, especially if your website is new.

4. Understanding Search Intent

This involves understanding why someone is searching for a particular keyword. Are they looking to buy something (transactional intent), find information (informational intent), or navigate to a specific website (navigational intent)?
