Google Ad Grants for UK Charities: What's Worth Your Time

Google Ad Grants is the most generous free marketing programme any UK charity gets handed. Up to $10,000 a month in search ads, every month, indefinitely, for as long as you stay eligible. Most charities I see have it set up, are technically using it, and are getting almost nothing out of it. The grant is paying for traffic that does not convert and that nobody at the charity can name.

That is fixable. The pattern below is what I have used to take Grants accounts from a few hundred clicks a month with zero attributable conversions to several thousand clicks with a tracked donate, sign-up or service-enquiry path. None of it requires a paid agency. It does require an hour a week and a willingness to delete what is not working.

What the grant actually gives you

Eligible registered charities get a credit of up to $10,000 a month for Google Search ads. The credit only buys search inventory, not YouTube or display. Bids are capped at $2 per click unless you use Smart Bidding (which lifts the cap). Accounts must keep a 5% click-through-rate average across the whole account each month, or risk suspension.

Those three constraints (search-only, low bid cap, 5% CTR floor) shape every decision below. If your account ignores any of them, that is usually where the leak is.

The five questions before you spend a penny

1. What is the single most valuable action a stranger can take on your site? (Donate? Sign up? Volunteer? Get a service?)
1. Do you have a landing page for that action that loads in under two seconds and asks for nothing else?
1. Do you have conversion tracking set up in Google Ads for that action?
1. Can you name three search queries a stranger would type to land on that page?
1. Do you have someone who can spend 20 minutes a week reviewing the account?

If the answer to any of those is no, fix it before building campaigns. Running ads to a vague page with no tracking is how you spend the grant and learn nothing.

The account structure that earns its keep

Three campaigns, not thirty

Most charities over-structure the account on day one. Start with three campaigns, by intent:

• Brand: your charity name and obvious variations. Tiny budget, high CTR, defends against competitors bidding on your name.
• Service or programme: the work people search for directly. "Free debt advice London," "youth mentoring Manchester." This is where the real volume lives.
• Action: people searching to give. "Donate to homelessness charity," "sponsor a child." Smaller volume, higher intent.

Add more later, only when the data justifies it. A 12-campaign account that nobody reviews is worth less than a 3-campaign account that someone tunes weekly.

Ad groups, tightly themed

Each ad group should focus on one theme with 5 to 15 closely-related keywords. Loose ad groups (everything thrown into one bucket) tank your relevance score and your CTR. The 5% CTR floor punishes loose ad groups quickly.

Three ads per ad group, always

Two responsive search ads plus one expanded text ad as backup, or three responsive search ads. Google rotates them, learns which performs, and concentrates spend. One ad per group is the most common Grants mistake and the easiest to fix.

The keyword discipline

Exclude branded-term lookalikes for competitors. Exclude job-related queries ("jobs at X"). Exclude generic single-word terms ("charity," "donate"). The Grants 5% CTR rule is what makes these exclusions non-negotiable. Loose keywords drag the whole account average down.

Use phrase and exact match more than broad match. Broad match looks tempting because it inflates impressions, but the irrelevant clicks it pulls in will tank your CTR and put the account at risk.

Landing pages do most of the work

A great Google ad pointing at a generic homepage is a wasted ad. For each intent (donate, volunteer, get service), a dedicated landing page does three jobs:

• Confirms the searcher landed on the right page in under one second.
• Removes secondary navigation that lets people drift.
• Has one primary action above the fold, with a button label that matches the ad headline.

If you only build one new landing page this quarter, build the one for your most-clicked ad. The traffic is already there. The leak is in the page.

Conversion tracking, properly

Set up at least one conversion in Google Ads (donation completed, form submitted, volunteer enquiry). Without it, the account is reporting clicks and impressions, neither of which tells you whether the grant is doing anything useful.

Conversion tracking takes 45 minutes to set up properly via Google Tag Manager and Google Ads. It pays back the first time you can tell the trustee board that the grant produced a measurable number of donations last month.

The monthly 20-minute review

1. Check account CTR. Anything under 5% needs attention before next month.
1. Sort keywords by impressions, descending. Pause the bottom 10 if they have zero conversions and CTR under 3%.
1. Sort ads by clicks, descending. Pause the lowest-performing ad in each group; write a new variation to replace it.
1. Check the search terms report. Add any irrelevant queries as negative keywords. Add any high-intent queries you had not targeted.
1. Skim conversions by campaign. If a campaign has zero conversions over 90 days, redesign or kill it.

Twenty minutes, twelve times a year, will beat any agency that bills for 'optimisation' but never tells you what they changed.

When to graduate to paid

Two signals tell you the Grants account has done its job and it is time to add a small paid budget: you are hitting the $2 bid cap on your most valuable keywords (Smart Bidding can help, but paid removes the cap entirely), or you have a campaign window (Christmas, an appeal launch) where Grants alone cannot get enough impression share.

Google Ad Grants is not free marketing. It is free media on a strict tenancy agreement. Treat it like a paid account that happens to bill someone else, and it will earn its keep.

The 30-day starter plan

1. Week 1: Confirm eligibility, set up the account if not already done, install conversion tracking.
1. Week 2: Build the three core campaigns. Write three ads per ad group. Add 20 to 30 negative keywords.
1. Week 3: Build or polish two landing pages (one for the highest-intent campaign, one for donate).
1. Week 4: Run the first monthly review. Document what changed. Schedule the next one.

In month two, you will have data you can act on. In month three, you will have a reportable conversion number. That is the difference between treating the grant as a line in the appendix and treating it as a working acquisition channel.
