Why Your Google Ads Leads Are Poor Quality (And What to Fix First)

The short answer

If your Google Ads bring in enquiries that go nowhere (wrong area, wrong service, price shoppers, spam), the campaign is doing exactly what it's been told to do. The instructions are the problem. In most accounts, it comes down to five things.

1. You're paying for the wrong searches

The keywords you choose are not the searches you pay for. Google matches your ads to searches it considers related, and "related" can stretch a long way. A plumber bidding on "geyser installation" can end up paying for "geyser installation course" or "DIY geyser repair".

Open the search terms report and read it like a customer list. Every search that would never become a paying client should become a negative keyword. Do this weekly for the first month, then monthly. It is the cheapest fix in Google Ads, and the one most often skipped.

2. Your tracking counts the wrong things

Many accounts count a "conversion" every time someone views the contact page, clicks a phone number, or loads a thank-you page twice. On paper, leads look healthy. In your inbox, they don't exist.

Check what each conversion action actually measures:

• Count form submissions only when the form is successfully sent.
• Count calls only above a minimum length, so misdials and hang-ups don't register as leads.
• Count WhatsApp clicks as a separate, secondary action rather than a full lead.
• Remove anything that fires on page views alone.

3. Smart bidding is learning from bad data

Automated bidding strategies chase whatever you tell them is a conversion. If junk enquiries count as wins, the system goes looking for more people like them. This is why lead quality often gets worse over time rather than better.

Once tracking is clean, give the campaign a few weeks to relearn before judging results. If you can, feed back which leads became clients, so Google learns from sales instead of form fills.

4. Your ad promises something your page doesn't

If the ad says "emergency plumber, 60-minute response" and the landing page opens on a company history, people either leave or enquire without reading. Both cost you.

The page someone lands on should repeat the promise in the ad, answer the obvious questions (area, price indication, how it works), and make the next step clear. If your site wasn't built with this in mind, the website redesign checklist covers what to sort out before any redesign.

5. Your offer doesn't filter anyone out

Good leads come from clear positioning. If your ads and page speak to everyone, you'll hear from everyone. Saying who you're for, where you work, and roughly what things cost will reduce the number of enquiries, and raise the number worth answering.

This is where advertising and brand meet. If you're not sure how to describe who you serve and why you're different, start with brand strategy vs brand identity.

Where to start this week

1. Audit your conversion actions and switch off anything that isn't a real enquiry.
2. Read the last 30 days of search terms and add negatives.
3. Check that each ad group sends people to a page that matches the ad.
4. Add one qualifying question to your enquiry form, such as area or budget range.
5. Give the account three to four weeks before judging the change.
