How to use negative keywords in PPC

Keywords are used to determine which searches will trigger your pay-per-click (PPC) ads. Having a solid understanding of how keyword bidding works will help you to reach your target audience and move closer towards your digital marketing goals.

For big advertisers with a large budget, showing up for searches that don’t drive conversions may not be a huge problem. However, for smaller businesses with a niche market, being visible for the wrong search terms could be wasting budget while driving non-converting users to your site. That is why your PPC keyword optimisation is so important.

Building a negative keyword list and having a clear keyword strategy can ensure you’re not showing for those unwanted terms.

What are negative keywords?

When used correctly, negative keywords will benefit your business and keep you within your marketing budget.  So, what exactly is a negative keyword?

They are essentially the opposite of your target keywords. By adding a negative keyword, you are informing Google that you do not want to appear for a specific search query. So, if a user includes your keyword in their query – your ad won’t appear.

In case you want a quick recap of how keywords generally work in PPC, you can find our previous blog post here.

Different types of negative keywords

1. Negative broad match

This is the default type of negative keyword. As long as a search query contains all of your terms, then your ad won’t be triggered. Your ad still won’t be triggered if your terms are in the wrong order or part of a sentence. Here’s an example:

Your negative broad match keyword is “Marketing agency.”

You won’t appear for:

  • Marketing agency
  • Agency in London marketing
  • Digital marketing agency 

 You will appear for:

  • Digital marketing
  • Marketing London

2. Negative phrase match

For negative phrase match, your ads won’t appear if a user searches your exact keyword terms in the correct order. If a query includes your keyword phrase (in order) along with additional words – it still cannot appear. If your keywords are in the wrong order, then it can appear. For example:

Your negative phrase match keyword is “Marketing agency.”

You won’t appear for:

  • Local marketing agency
  • Marketing agency 
  • Digital marketing agency 

 You will appear for: 

  • Agency marketing
  • Agency specialising in marketing
  • Marketing London

3. Negative exact match

For this type of negative keyword, your ad will not show if a user search searches for your exact terms, in the correct order, without any additional words. If you’re worried about appearing for a specific query, then you can add it as a negative exact match. (Of course, we personally would never add ‘marketing agency’ as a negative! But, we will keep using this as our example). So here’s how it works:

Your negative exact match keyword is “Marketing agency.”

You won’t appear for:

  • Marketing agency

 You will appear for:

  • Agency marketing
  • Marketing agency London
  • Digital marketing agency  
  • Marketing

How to choose your negative keywords 

There are different ways you can find and research your negative keywords. Sometimes your negative terms will be obvious – but using real data can make sure you’ve covered all the right keywords. Our favourite tools are Google’s Keyword Planner and Search Terms Report. 

Keyword Planner 

A great tool that most businesses will benefit from using is Google Ads Keyword Planner. This tool allows you to look at real user query data and understand how people search.

How does it work? You can search for a term of your choice, the tool will display a list of related keyword searches. You’ll also be able to find out the search volume and competition for each suggested term. This is a popular way of gathering new keyword ideas – but is equally as useful for spotting those terms you want to exclude.

We suggest looking through your list and noting any terms that you wouldn’t want to appear for. Once you’ve found those irrelevant terms, you can add them to your negative keyword list to avoid driving the wrong traffic to your site.

Search Terms Report

A Search Terms Report provides you with a list of search queries that have triggered your PPC ad. This is another way of avoiding spending money or showing your ad to people who probably won’t be interested. 

On the report, you can sort your results in a way that will help you to put together your negative keyword list without up taking much of your time. You can sort by the highest number of impressions to the lowest – which will give you a good idea of how most people are reaching your ads.

A great part about this is being able to see which terms have the highest click-through and conversion rates. You can find those users that are seeing your ad but not engaging with it. You might find that some keywords you predicted as high-performing are not generating the results you expected. So, if you find a term that is relevant but not actually leading to clicks or sales – you could add that as a negative.  

Do your research

While data is great, there is no harm in doing some extra research, for example:

  • You can brainstorm with your team about any search terms you don’t want to appear for. It’s always helpful to get ideas from a different perspective.
  • You could perform an organic Google search using your keyword to find more negative terms. Everything that appears as a result of your search is considered relevant by Google. So, you can look through the first few pages and spot any terms that you don’t think are likely to lead to a conversion. This can help to find those ‘exactish’ terms.

Things to remember

  • Track the performance of your campaign and make adjustments throughout – things are always changing on SERP.  
  • Research, research, research! Using the methods we’ve highlighted can help you choose your negative keywords and avoid missing out on potential customers. 

How to add your negative keywords

Once you’ve got a list of negative keywords that you’re happy with, you’ll just need to add them to your account. Google Ads have got a helpful step-by-step guide to help you add keywords to your Search and Display campaigns. You can find it here
