There’s no question that keyword research is a vital part of PPC account strategy and planning. These days it’s more sophisticated than ever before. It’s possible to spend hours researching and tracking down winning keywords for your ppc campaigns. Fortunately, there are plenty of tools out there to help you conduct this research with ease. See our list below for 5 free tools for PPC keyword research.

1. Ubersuggest – Google Suggest for PPC Keyword Research.

The original Ubersuggest was based on Google’s suggestion tool, it would allow you to add any keyword and generate at scale all of the google suggestions for different characters and numbers. Google’s suggestions tool, Google Suggest is powered by search volume. Entering some of your core keywords into this tool can give you a view of what Google Suggest would show if you typed any other character or number. 

Since then, Ubersuggest was been acquired by Neil Patel’s NP Digital and after some changes to the interface, it now offers a slightly different experience. Mostly as it is now primarily a paid tool. If you’re still looking for Google suggestions at scale, a good alternative is Keyword Sheeter which offers less additional data but is free.

The updated Ubersuggest, whilst a paid tool, does now incorporate additional data from the Google Keyword Planner, including approximate search volume, competition and cost per click. This means you can see both sets of data and toggle them within the same window when assessing suitable PPC keywords. This is great news if you don’t have an Google Ads account and were struggling with access to Keyword Planner.

This can also be a great tool for finding negative keyword ideas. Allowing you to prevent irrelevant ppc search terms before they have a chance to waste any of your budget.

2. – Instant & Live Keyword Suggestion Tool

Keyword Guru is great for those looking for the most common keywords across platforms, it features Google, Yahoo, Bing, YouTube, Amazon, Ebay and Google Play. As you type each platforms column is updated with a list of their respective top keywords. There are no metrics or data sets to speak of, however its speed is great for quick checks on the fly. Their free plan offers 3 Keyword Guru searches per day

3. Google Correlate  – Like Google Trends, but for PPC Keyword Research  – Google Correlate was shut down on December 15th 2019. 

We all know and love Google Correlate’s more famous sibling, Google trends. Perfect for checking seasonal trends or historic growth. Take a look at the graph for fidget spinners below.

However, launched in 2011, Google correlate is far more useful for keyword research. It allows you to enter a search query then see it correlated with other trends both online and in the real world. This can be useful to find any related trends, topics or keywords. Admittedly, correlation doesn’t equal causation (see below, it turns out ‘iced coffee’ and ‘gas golf cart’ have a correlation coefficient of r=0.9653

Correlation ≠ Causation


4. Answer the Public

This tool is amazing. Similar to Ubersuggest, its top section is focused more on popular questions that people are asking. It’s primarily used as a tool for content creators, but definitely has it’s uses for keyword research.

Add to this the site itself, it’s really nice to look at. The visualisations are amazing and can provide great insights. It’s so addictive, you may even forget the keywords you were supposed to be researching in the first place.

This tool has also been acquired by Neil Patel and so offers limited free use or a paid plan.

As an update, we’ve recently started using Answer Socrates and have found this to be a great free tool which functions just like how Answer The Public used to

5. initially looks very similar to Ubersuggest, however it can produce up to 750 Google Suggest results per search. This provides some great long tail keyword suggestions vital for ppc keyword research. To pull in any associated metrics, you will need a ‘pro’ account. For now, the free version should give you more than enough data.

Hopefully you’ve found the above resources useful. Next time you’re doing some ppc keyword research why not give one of them a try. If you’d like to discuss more or suggest another great free ppc keyword research tool, please get in touch.
