What is SEO Keyword Research?
Keyword research is the process of identifying and analyzing specific words or phrases (keywords) that people use in search engines when looking for information, products, or services online. This practice is crucial for various digital marketing strategies, particularly search engine optimization (SEO) and pay-per-click (PPC) advertising.
Importance of keyword research in SEO
Let’s start by answering the question… Why are keywords important?
Simply put, they are the guiding light for search engines to understand what your website or blog post is about to match it with users’ search queries.
By optimizing your website with focus keywords, you will increase your chances of appearing in the top positions of search engine results pages (SERPs).
However, deciding which keywords to use is not a matter of faith or luck. There is hard work behind it, and you must rely on the best keyword research tools.
These tools will help you understand the search volume (or how many people use it every month) and the difficulty of ranking for it. They give you valuable insight into the queries users are inputting to find relevant content on Google and other search engines.
Plus, if you use the inbound method, your goal is creating content around what people need or want. Keyword research is the most innovative and easiest way to understand that.
Different types of keyword
However, there are different types of keywords you can use. It’s important to learn the differences between them so you can decide which ones to use for each page and article you publish on your site.
User’s search intent
You can categorize keywords based on the user’s search intent. There are 4 types of keywords:
- Informational: The user wants to find information about a specific topic.
- Navigational: the user is looking for a particular page or website.
- Commercial: The user wants to learn more about a brand, product or service.
- Transactional: The user is ready to take an action (register, download, subscribe, buy, etc.).
SEO
You can also find keywords categorized by their use in terms of SEO:
- Seed: The starting point of your keyword research. Let’s say your business sells t-shirts and you want to rank a blog post about t-shirts for runners. Your seed keyword would be “t-shirt”.
- Long Tail Keyword: These are more specific terms that are less competitive, but get smaller amounts of monthly traffic. Staying with the same example, your long tail keyword would be “t-shirt for marathon runners”.
- Low-competition keyword: It’s usually easier to rank for these because not many brands are generating content for them. An example would be “blue t-shirt for marathon runners”.
- Niche keywords: Clear and very specific topics that appeal to a relatively small portion of the market. Example: “ethical t-shirt for marathon runners”.
- Brand keyword: Refers to search terms that include your brand. For example, “branded t-shirts for marathon runners”.
- Competitor keyword: Using your competitor’s name to rank your products and services in search engines. “Competitor branded t-shirt for marathon runners”.
At Sortlist we always suggest that you start with long tail keywords. Although they don’t get as much traffic as you would expect, they are the type of keywords that are easier to rank for. So start there and then work your way up to more competitive terms.
Summary
In summary, keyword research tools are indispensable for any effective content strategy. Whether you choose a paid or free tool, the key is to find one that meets your specific needs and budget. Paid tools like SE Ranking, Semrush, and Ahrefs offer extensive features and comprehensive keyword data, while free tools like Google Keyword Planner and Google Search Console provide valuable insights without the cost.
Remember, the right keyword research tool can make all the difference in your SEO efforts. By understanding what your audience is searching for, you can create content that resonates, boosts your search engine rankings, and drives more traffic to your site.
Take action today and start exploring these tools to enhance your keyword research and SEO strategy. The digital marketing world is constantly evolving, and staying ahead requires the right tools and a proactive approach.
