How to Reduce Cost per Conversion in Google AdWords with Filters

When you’re managing paid campaigns, there are moments where you have to make quick decisions based on your campaigns’ objectives, budget, and target CPA. However, in order to take effective measures, its important to take all factors into account and then take actions.

Strategy Based Filters in Google Adwords

It’s important to understand what you are trying to achieve before you build a strategy. So, before you begin, identify your purpose from some of the choices:

  1. To reduce cost per conversion
  2. To keep your position between 1-2 for branded keywords, or
  3. To spend more on converting keywords and less on others, etc.

In this post, I’ll be sharing a set of Google Adwords filters that can be used to increase the return on investment (ROI) on your Google Adwords Search campaigns.

To do this, I will first need to find out the keywords that are sucking my money and not getting me any conversions. To identify this, I will use the following filter and then label them.

  1. Conversions = 0
  2. Clicks >= 10 or {30% of daily clicks}

conversions filters


Using this filter, I can see the keywords that are only getting me clicks, but no conversion. I am going to label them as “Bad Keywords” and then pause them for now.


Remember, if your objective is branding, then these keywords would be great for generating traffic to your site. However, we are trying to reduce the cost per conversion. Therefore, we will need to pause these keywords for now.

Note: Pause these keywords, if you have enough history and data to show that these keywords have never generated a single conversion over their number of clicks.

Identify Keywords with Highest Conversions

My second step would be to identify the keywords with highest conversions and optimize the bids to spend the maximum budget on them.

Use the following filter:

  1. Conversions > 10 Or {10% of your daily conversions}

Now, label these keywords as “Good/Imp” or “High Conv”. These keywords are important for bringing conversions in your account. We want to make sure that the bids are competitive enough to show our Ad copy in top positions of SERPs.

Once you see these keywords, apply additional criteria to the same filter.

  1. Max CPC < Top page bids
  2. Average Position worse than 2

filter conversions

Select these new set of keywords and edit their bids to raise to top page bids. Please note that if your history shows that you do not perform on top ranks, then this may not be a good idea.

Once done, time to spare some money to get for more conversions. For doing this, let’s focus on the keywords with good Quality Score.

Create a filter using the following criteria:

  1. Quality Score >= 7 or 8
  2. Max CPC Bid > Top page bids
  3. Average position better than 2

filter quality score

Now, select these keywords and reduce their bids to their actual top page bids because this is what you should be actually paying based on your QS. So, why pay more?

Note: If you do not want to target position 1, you can remove the third criteria.

Do not forget to select these keywords and label them as “High QS”.

Labeling Your Keywords

Using Labels for Adgroups, keywords, and even campaigns would make them look different from each other. This helps to increase the visibility of the data you want to actually see while you are looking at a table with so many numbers and metrics, which in my case is everyday.

Here are some examples of different labels you can use to optimize a set of keywords.

For “performing keywords” I like to use labels such as “Fav”, “Imp”, “Most Conv”, “High QS & Conv”, etc. For non-performing keywords, I usually label them as “Bad Keywords, “Low QS & Conv”, etc. Honestly, you can name them as you find fit, but the goal here is to separate them from the crowd.


Using filters based on your strategy could actually make things less complicated. The idea here is to cut our cost for non-performing keywords and spend more on keywords that are performing well and meeting our goals. I call this a balancing strategy to manage keywords bids.

Let me know what you think of the above strategy and if you have some other variations on filters for managing your keyword bids. Here is another great article that talks about useful filters that you can try to improve you return on investment.

    I like section 2 with the recommendation “Select these new set of keywords and edit their bids to raise to top page bids. Please note that if your history shows that you do not perform on top ranks, then this may not be a good idea.” Problem is, most of my campaigns use a CPA (target) bid strategy. Is there a way to adjust on a keyword level when the campaign uses a bid strategy other than CPC?

      @Tim – Great Question! As you are using CPA bids, you already have agreed to the fact that the system can adjust your bids to get you the best ROI. So, making bid changes will only result in contradicting system suggested bids. May be that’s why system does not allow to adjust bids if there are not manual bids.
      However just to keep working on the optimization for improving the ROI, it might be a good idea to divide the keywords into different campaigns if you feel a lot of them does not bring conversions for you but you still want to keep them running. That we can you can test the bid strategies differently for performing and non performing keywords.

    This is a no-brainer just as a personal organizational tool. In conjunction with ongoing refinement of your keywords, it’ll impact your bottom line more than any other single marketing change short of hijacking a television station Max Headroom style.
    Just remember, keywords evolve to fit the market. What’s a bad keyword now, might later turn over the best results, so don’t grow complacent with any that you’ve marked as bad. Always consider refining and looking over your past keywords to see if it applies to the current state of your marketing campaigns!
