Google Ads can deliver qualified local leads for Hertfordshire businesses within days. They can also drain your budget with zero return. The difference is in how campaigns are set up and managed.
Here are the most common mistakes we see when Hertfordshire businesses run their own Google Ads.
Mistake 1: Broad match keywords without negatives
If you are a plumber in Watford and you bid on "plumber," you will get clicks from people searching for "plumber jokes," "how to become a plumber," and "plumber salary" — none of whom want your services.
Properly configured campaigns use exact and phrase match keywords plus a comprehensive negative keyword list. This alone can reduce wasted spend by 40-60%.
Mistake 2: Sending ads to your homepage
Your homepage is not a landing page. If someone searches "emergency plumber Watford" and clicks your ad, they should land on a page specifically about emergency plumbing in Watford — not your homepage where they have to navigate to find what they need.
Dedicated landing pages improve conversion rates by 2-5x.
Mistake 3: No conversion tracking
If you cannot tell which keywords are generating phone calls or form submissions, you cannot optimise your campaign. Conversion tracking is essential and often missing from self-managed campaigns.
Mistake 4: Letting Google "optimise" without oversight
Google's automated suggestions ("expand your audience," "increase budget") are designed to spend more of your money. They are not always in your best interest. Every automated recommendation needs human review.
Mistake 5: Running ads all day when your business is closed
If your business only handles enquiries Monday-Friday 9-5, running ads on Saturday evenings is wasting budget on leads you cannot respond to quickly — and slow response kills conversion rates.
What a well-run Google Ads campaign looks like
For a Hertfordshire SME with £750/month ad spend, a well-managed campaign should generate 15-30 qualified local enquiries per month. If you are spending similar amounts and getting far fewer results, your campaign needs attention.
