What is Google Keyword Planner tool:
Google Keyword tool is an official product from Google, which gives us a traffic estimation of our target Keywords and also help in finding more relevant and related Keywords for your niche. Few Important things to know:
You need to have a Google Adwords account to use Google Keyword Planner tool. It’s free, and you don’t need to spend any money to use this tool. You can simply create an Adwords tool and start using it.
You can also search for existing Google Adwords coupons to create one free account for yourself, and start using Keyword Planner tool.
This tool is created to target Adwords advertisers, but it still gives a great deal of information when it comes to finding the right keyword for your blog and articles.
This is what the homepage of Keyword Planner tool looks like. All you need to do is enter your target Keyword that you want to start searching for. After that, you can add filters such as for which country you want to target your keywords (In below example, All location is selected).
Using Keyword planner tool
1) Enter your product or services:
This is the place where you will put your target Keywords. For example, my next post in on Keyword research, and I’m not sure what keyword I should be targeting that post for, I will do some searches based on my knowledge like you see in the example, and it shows me results globally and local search. The idea here is to find a Keyword that has good traffic but low competition. If you are working on a blog for the long-term goal, you can also target high competition Keyword, using resource pages. For ex: WordPress guide. It makes take time before you see your keyword ranking at the good position. Below image illustrates the difference between Broad search, Exact search and phrase search.
Broad Match Traffic
2) Search type:
This is one important column that you should be taking care of. There are three options for search type:
Exact Match: Exact searches, shows the traffic for exact match Keyword. For example, if you search for WordPress SEO in exact match, it will be different from broad search in a great way. My suggestion, prefer Exact search when you are doing research for your micro-niche site and broad search when you are writing on the personal blog. Ex: Keyword Research Broad Match: Broad Match is my favorite, as it let me target long-tail keyword, and your traffic is not limited to exact match words. For Bloggers, broad match is useful, but that again depends on your blog type and target. Ex: “Keyword-based research” Phrase: Phrase type is useful when you need Keyword in an exact phrase. For example: “Best Keyword Research”. Keyword position won’t be changing, but it gives the data for traffic, that your Keyword might be getting for phrase search.
