Without an effective keyword strategy, you won’t be able to improve your website’s search engine rankings, establish a presence on social media or generate sales.

Keywords are necessary to form a bridge to connect users with the content they’re looking for.

So do you just try to find the most profitable keywords?

best keyword research tools 2019

What you will find is that the most profitable keywords for your niche are probably not viable.

The more profitable keywords have much higher competition and you simply can’t compete against those with more funds, manpower and experience.

The trick is to find keywords by expanding broader, competitive terms into long-tail keyword variations.

Long tail keywords are more specific and so they’re less competitive and easier to monetize if you’re a smaller brand.

Here are some of the best keyword research tools to help you find the best keywords to rule the Google rankings.


Ubersuggest keyword tool

Ubersuggest is a free keyword tool. Start your keyword research on Ubersuggest by entering your seed keyword, setting a region preference and clicking ‘search.’

You will be presented with an overview page that shows you various metrics, such as:

  • average monthly search volume
  • SEO difficulty, and
  • cost-per-click.

Ubersuggest Limitations:

You will receive a limited number of keyword suggestions but this is to be expected as it is a free tool.

You can only export your keyword research data as a CSV file or copy it to your clipboard.

You can’t sort your keywords into lists, do any additional analysis or save information to the cloud for future use.

If you’re a beginner blogger, this is a good tool to start with. You will be able to design your content around the specific keywords you select.

If you need help with content, consider reading essay writing services reviews to find writers to help you.

Good features::

The interface is fast and intuitive so even beginners can use it. The Traffic Analyzer feature is probably the best feature.

You can check the target keywords of any domain, enabling you to discover those your competitors are using.

Pricing: Free

Google Keyword Planner

google keyword planner

Google AdWords Keyword Planner is a free tool and although it isn’t a standalone tool, it has become a trusted keyword research tool that has acquired a large user base.

You can obtain a large number of long-tail keyword suggestions absolutely free.

You can use this tool for finding new keywords and viewing search volume as well as finding metrics for your current keywords.

It includes metrics such as:

  • average monthly searches
  • competition, and
  • average CPC bids.

In the left-hand menu, navigate to “Grouped ideas” and you’ll be able to sort your keywords according to themes.

You can use a range of filter options to find the exact keywords you need.

If you want to use the keywords for a PPC campaign, you select them and click ‘add keywords’ on the blue bar at the top. Select ‘add to plan’ on the blue menu and you will get a forecast on how well a keyword could perform.


Before you can use the tool, you have to set up an AdWords account. The interface is not that user-friendly but you should be able to find what you need.

Another disadvantage is the huge search volume ranges that make it difficult for those who want to balance competition and profitability.

Good Features:

The keyword planner will give you plenty of keyword suggestions and you can group similar keywords. It can help if you need forecasts for PPC campaign keywords.

Pricing: Free


semrush keyword tool

SEMrush is not a typical keyword research tool. It’s a digital marketing analytics and SEO platform with a powerful keyword research tool included.

All you need to do is to add your competitor’s URL and you will be able to see all the keywords ranking for the site.

You can target some long tail keywords to beat your competition. If you see a domain with plenty of organic search traffic but a low traffic cost, you will know that the keywords they rank for don’t convert into buyers.

You can use the Keyword Magic tool to enter a keyword and pull up keyword suggestions from the massive database.

You’ll get a long list of long tail keywords that include the keyword you entered. You can go through the results to find phrase matches, exact matches, and related keywords.

Keyword ideas are sorted into four categories, including newly discovered ones and questions.

When you click on one of the categories, you are able to access filter options and you can view metrics.


Ahrefs is not that different from SEMrush and once again, if you want to use the keywords tool, you have to pay a monthly Ahrefs subscription that includes features you may not need.

Good features:

You will have to create a new list if you haven’t made one yet.

Limitations: It may not give you as many keyword suggestions as other more expensive tools (more than Ubersuggest though!).

You can save your keyword lists, a feature that free tools don’t provide. KWFinder has an “Interest over Time” tracker. This enables you to check our relevant your keywords remain over time.

Jaaxy is a straightforward but powerful keyword research tool. It gives you many different keyword ideas with helpful data on each keyword it generates.

Serpstat caps all reports, not just for keyword research, to 100 results for the basic plan. It’s worth paying more for a higher priced plan to get 15,000 results per report.


spyfu keyword tool

SpyFu is very useful if you’re trying to stay ahead of the competition. It can help you understand your competition’s SEO strategies and discover untapped markets.

Unlike the tools that expand seed keywords, the focus of this tool is on helping you to spy out your competitors’ keywords.
