But first, a quick look at why keyword search is important.

How Does Keyword Research Help You?

i.                  It Guides Your Direction

Researching for keywords gives you a deeper sense of focus and direction because it helps you unearth other keywords and ideas that you may not have had before; this helps you focus on only the best topics within your niche.


ii.                Brings New Ideas

You may have an idea in your mind, so when you do keyword research you tend to get more information about it and this can help you expound more on your idea. It keeps the ideas flowing and brings in more ideas.

iii.              Effective Use of Time

Keyword searching may be a time-consuming activity, however, it tends to also save you from more waste of time by driving you exactly where you need to be. During the keyword research, you can mark potential articles or products that you can work on in future and thereby giving you a next plan of action that in turn will save you lots of time.

iv.               Gets You the Right Audience and Offers You Customer Insights

Of course, this is one of the most important reasons why you‘re doing a keyword search. It keeps you focused on the right audience. This will enable you to master a lot of customer insights. It’s particularly possible if you do some forum search or Google research.

Getting better insights helps you target better and therefore offer better to your clients.

v.                You Get Insights on the Best Possibilities to Rank in Search Engines

Google is the most advanced search engine, so when doing your research with that in mind, you gain from all the exposure you get, and this includes getting competitive keywords that will fine-tune your strategy. It will also enable you to pick keywords with the lowest competition but with the highest likelihood of getting listed in the top spots in the Google search.

vi.               It Covers Your Competition Analysis

Keyword research helps you determine whether a certain selected topic is worth pursuing or not, it helps you be more specific even within a niche. To get a good competition analysis, you have to find out how authoritative competitors’ websites are; based on the keywords you’re deliberating on.

How SEO Keyword Research Works

This is about identifying keywords that can help rank your website. For instance, if you want to write about pet food, your content should include the word pet food throughout the article. But the likelihood is that many other pet websites are already competing for that same phrase. And this is why it’s important to use long-form phrases.

 For example, “organic pet food and product” is a long-form keyword that may not be used by every competitor but has a higher chance of ranking your blog. Long-form keywords are generally more than 4 words and have a lower search volume. For this reason, they have a higher buyer intention and are also easier to rank for.

So, with this clear picture of where you want to take your content, here are the best SEO keyword search tools:
