Five negative keyword lists to cut wasted Google Ads clicks
Stop paying for searches you don’t want. Here are the five negative keyword lists I normally use when building Google Ads campaigns for service businesses.

An audio visual (AV) rental business owner contacted me about running Google Ads.
His ideal customer is a business exhibiting at a trade show or putting on an event in Houston. They're looking for a few big screens for the booth or stage, and a sound system. They often come from other cities.
He doesn't want enquiries from:
This means we need to solve two separate targeting problems:
Here's how I'd approach it.
The first would target people across the US. It'd have keywords that included Houston or an event venue in Houston.
For example:
That gives someone booking equipment for Houston from New York a route to our hero.
The second campaign would target people in the Houston service area. Its keywords wouldn’t have to include Houston.
For example:
For both campaigns I'd include the word Houston in the ad headline. This should reduce clicks from people wanting equipment in other areas.
I’ve used this geographical split before for an immigration lawyer where we had hit a ceiling on leads in his city. The nationwide campaign added a few more cases every month so it was worth doing. I don't know if it'll be worth doing here. We'll know once we've tested it.
Someone who searches for "large screen tv rental" could be planning a corporate event. Or they could be planning a Super Bowl watch party at home. (Insert your preferred sporting event here.)
I'd choose our keywords carefully and add negative keywords, but this isn't likely to be enough to stop all B2C enquiries.
What's helped for other B2B clients is:
That way someone who searched for say "large screen rental" would see an ad for a large screen rental. If they clicked the ad they'd see a page about large screen rentals. Someone who searched for sound system rental would see a sound system ad and a sound system page.
When the search, ad and landing page all match what someone is looking for, more clicks tend to turn into enquiries.
But, we'd also have to have a generic page listing all the services. This one's for people who searched for something like "AV hire service Houston".
I’ve written plenty about building landing pages that turn clicks into enquiries. If you're interested here's a good place to start: https://pete-bowen.com/topics/landing-pages
When you're looking for B2B leads in a market that also has B2C searches, it's important to tell Google which leads are good. That way Google can learn which kinds of enquiries we want more of.
In technical terms this is called optimising for qualified leads using offline conversions.
I normally work with the business to define what makes a good / qualified lead. In this case it'd probably be something like:
A qualified lead is a useful signal to Google because:
Even if the lead never turned into a sale, it's still the kind of enquiry we want more of.
At this stage I've got a broad outline, but there are a few things I'd need to know before launching any ads.
And we also need to work out who is the most likely customer so we can write ads and landing pages that resonate.
These could be quite different customers. They might all need AV equipment, but they won't necessarily search for it in the same way.
Possibly. But I'm not ready to recommend going all in on Google yet.
We've got a reasonable idea of how to tackle the two targeting problems. We can reach people outside Houston who need equipment in Houston, and we've got ways to reduce consumer enquiries.
But that doesn't mean Google Ads is a good fit.
I'd recommend starting with a pilot campaign.
The pilot would let us test if we can generate enough of the right enquiries at a cost that makes commercial sense. We'd also learn which searches produce good enquiries, which services attract the most interest and where we're wasting money.
At the end of the pilot, we'd have some real data to help decide whether to continue, change our approach or stop.
The question isn't if Google Ads works for AV companies. I'm reasonably confident it would. We need to find out if Google Ads works for this company. The pilot would confirm this.

When Google matches the wrong search, your ad copy can stop the click. What happens when Google writes the ad to fit its mistake?
If nobody can help your leads, why keep paying for them? Here’s what I’ve seen after years of pausing and restarting clients’ Google Ads.
It is almost always cheaper to get a happy customer to return than to win another one through advertising.
If every enquiry looks equally valuable, Google will chase quantity. Does it ever learn which leads actually become customers?
