Your charity's Google Ads not converting? Here's why – and what to do about it

Before we troubleshoot, it's worth being clear about what conversion actually means for your charity, because it isn't always a donation.

A conversion is any meaningful action you want a visitor to take: signing up to your newsletter, completing a volunteer application, downloading a resource, registering for an event, or yes, making a donation.

If you haven't yet defined and set up conversion tracking in your Google Ads account, that's actually a great place to start because, without it, it's hard to know what's working and what isn't.

Google requires Ad Grant accounts to record at least one meaningful conversion per month (Google Ad Grants policy, 2025), so getting this in place is both best practice and a compliance must.

One of the most common, and most fixable, reasons ads underperform is keyword targeting that's a little too broad.

Generic terms like "charity" or "donate" attract lots of traffic, but not always the right traffic.

The person searching "donate to a cancer charity UK" is much more likely to convert than someone who typed "donate" with no particular cause in mind.

High converting Google Ads are almost always built on specific, intent-rich keywords – what the industry calls "longtail" terms. They attract fewer clicks, but those clicks are far more likely to result in action. Think of it less like casting a wide net and more like fishing in the right pond!

A few things worth reviewing:

• Could your keywords be more specific to reflect real search intent?
• Do you have negative keywords in place to help filter out less relevant traffic?
• Are any keywords sitting at a Quality Score of 1 or 2? Pausing those tends to lift overall performance pretty quickly.

One of the most impactful things you can do for your conversion rate costs nothing ... it's just making sure your ad and your landing page are telling the same story.

If someone clicks an ad promising "free counselling for young people in Manchester" and arrives on a generic homepage, they'll likely leave before they've had a chance to engage.

Keeping that thread consistent all the way through – from search term to ad copy to landing page – makes a significant difference.

A strong landing page will:

• Reflect the specific promise made in your ad – lead with the service or message that brought people there
• Echo the keywords from your campaign – this also helps your Quality Score
• Have one clear call to action – one obvious next step tends to outperform several competing ones
• Load quickly and work on mobile – most people are searching on their phones, so a smooth mobile experience is non-negotiable

Quality Score is Google's measure of how relevant and useful your keywords, ads, and landing pages are, and it has a meaningful impact on how often your ads are shown.

A higher Quality Score means better visibility, even within the constraints of the Ad Grant.

The good news is that Quality Score responds well to the kinds of improvements already mentioned: tighter keyword targeting, more relevant copy, stronger landing pages. It's a virtuous circle: small improvements in each area tend to compound over time.

If your campaigns have been running for a while without much traction, Quality Score is a useful place to look for clues.

Ad Grant accounts need to maintain a 5% click-through rate at account level. Given that the sector average sits at around 4.41%, it's a very achievable target, but it does require keeping an eye on which campaigns are performing well and which might need a refresh or a rest.

The fix here is usually a combination of more targeted keywords, sharper ad copy, and regularly reviewing what's in your account. None of it is complicated, it just needs consistent attention.

High converting Google Ads are built through iteration rather than inspiration.

Running a couple of versions of each ad simultaneously, with different headlines, descriptions, or calls to action, and giving them time to gather data is one of the most reliable ways to steadily improve performance.

Most experts suggest waiting at least a week before drawing conclusions from new campaigns, and preferably longer. The key is to keep refining based on what the data tells you rather than gut feeling alone.

I worked in charity marketing long enough to know that the challenge is rarely a lack of effort or even knowledge, and it's almost always resource or capacity.

When I was managing Google Ads alongside everything else on my plate, the hardest part was finding the time to actually do it consistently.

Here's the thing: managing a Google Ad Grant well is genuinely rewarding when it's working. But it does need regular attention – keyword reviews, copy testing, compliance checks, performance analysis – and for most lean charity teams, that's a lot to sustain alongside everything else.

If you're doing your best with the time you have and still not quite getting there, it might be less about what you're doing and more about how much bandwidth you have to do it.

That's exactly what the Access Charity Ad Grants managed service is designed for – taking the application and ongoing management off your plate entirely, so your grant is always optimised, always compliant, and always working as hard as it can for your cause.
