1. Keyword Planner
Google’s Keyword Planner is the most popular keyword research tool that helps webmasters to search for keywords and analyze them. In comparison with other keyword research tools, Keyword Planner retrieves the greatest number of keywords for any search. This tool helps you to know the keywords that your competitors are ranking for. It also allows you to customize your searches using filters such as location, negative keywords and language.
Even though Keyword Planner was initially created for Google AdWords users, everyone can use it to search for keywords that will generate traffic to their websites. The tool is designed for advertisers and thus it is of less help to publishers.
Keyword Planner suggests keywords that are too broad. This means it does not find very unique keywords. Therefore, use other keyword research tools to find unique profitable keywords.
2. Keyword Tool
Keyword Tool is very resourceful when you need lots of unique and long-tail keywords. It relies on Google’s search suggestions to pull out over 750 long-tail keywords for any search. A key feature of Keyword Tool is that it suggests questions that may be formed from your seed keyword. These questions can be used to create new posts.
For a beginner, the Keyword Tool free version is enough to carry out enough keyword research.
However, the free version may not be reliable for a comprehensive keyword analysis. This is because it does not provide crucial analysis data such as keyword competition and monthly searches.
UberSuggest looks for all the possible keyword strings for your seed keyword. As a result, this tool retrieves so many keywords that are more than enough for your project. UberSuggest gives you various long-tail keywords that can bring huge traffic to your site. It also boosts your creativity by providing lots of keyword ideas.
UberSuggest does not provide information on keyword competition and search volume. Therefore, use other keyword research tools to check these factors.
4. Keyword Eye
Keyword Eye provides several keyword research features for free. This tool enables you to customize searches based on filters such as country and language. The tool can also calculate the potential of a keyword in terms of its competitiveness and monthly searches. Keyword Eye provides options for checking synonyms and keyword search queries. The display window of this tool is quite narrow, thus you have to go through the tiring task of scrolling down to the end of results.
