Google Ads for lead generation: a setup that brings real enquiries

Google Ads is the fastest way to put a business in front of people who are searching for what it sells right now. It is also the fastest way to spend a budget on clicks that never become customers. The difference is almost never the ad copy. It is whether the account is built around leads you can measure.

This guide describes the setup we use for service businesses that want enquiries: quote requests, calls and booked meetings.

Step 1: Track leads before you spend anything

Google's bidding algorithms optimise for whatever you tell them is a conversion. If you tell them nothing, they optimise for clicks. If you count page views of the contact page, they find people who look at contact pages.

Before launching, make sure these work:

• A generate_lead event in GA4 (or a Google Ads conversion tag) that fires once, only after a successful form submission. Our GA4 setup guide shows how.
• Call tracking for calls from ads (Google's call extensions with a forwarding number) and clicks on your phone number or WhatsApp link on the site.
• Consent Mode v2, if you advertise in the EU, UK or Switzerland, so conversions are modelled when visitors decline cookies.
• Enhanced conversions for leads, which sends a hashed email from the form so Google can match conversions more accurately.

Import the lead events into Google Ads as primary conversions. Keep softer signals (such as clicks on an email address) as secondary, so they are reported but don't steer bidding.

If your numbers already disagree between your inbox, GA4 and Google Ads, fix that first: GA4 not tracking conversions: 12 fixes.

Step 2: Structure campaigns by intent

Group searches by what the searcher wants, not by how your services are named internally.

• High intent: people looking to buy now, such as "web design agency Berlin", "Google Ads management cost" or "technical SEO audit". This is where most of the budget should go.
• Research intent: "how to set up GA4", "Next.js vs WordPress". Cheaper clicks but few immediate leads; often better served by content and SEO.
• Brand: searches for your company name. Cheap and protective, but report it separately so it doesn't flatter the results of non-brand campaigns.

Start with one search campaign per main service, each with a handful of tightly themed ad groups. A small, focused account learns faster than a sprawling one.

Step 3: Choose keywords and match types carefully

Use phrase and exact match for your core terms at the start. Broad match can work well once the account has reliable conversion data and Smart Bidding, but on a new account with little data it tends to drift into loosely related searches.

Look at the search terms report every week for the first two months. This shows the actual searches that triggered your ads and is the single most useful screen in Google Ads.

Step 4: Build a negative keyword list from day one

Negatives stop ads from showing on searches that will never convert. Common examples for service businesses:

• Job seekers: jobs, career, salary, internship
• Do-it-yourself and free: free, template, tutorial, course, download
• Wrong service or wrong size: competitors' product names, consumer terms if you sell to businesses
• Places you don't serve

Add new negatives from the search terms report every week. Keep shared lists at account level so every campaign benefits.

Step 5: Send clicks to a page that matches the search

The landing page should continue the conversation the ad started. Someone searching "Google Ads management for B2B" should land on a page about exactly that, not on your homepage.

A good lead landing page has:

1. A headline that echoes the search
2. Who the service is for and what it delivers
3. Proof: results, clients, process
4. A clear idea of price or a way to get an estimate
5. A short form above the fold on desktop and close to the top on mobile
6. Fast loading on a phone

Landing page speed and relevance feed into Quality Score, which lowers your cost per click. Our business website checklist covers the details.

Step 6: Write ads that pre-qualify

Responsive search ads combine up to 15 headlines and 4 descriptions. Include the main keyword in a few headlines, state who you serve, and mention something that filters out the wrong clicks, such as a price indication or minimum project size. A click you don't get from someone who could never afford you is money saved.

Add sitelinks, callouts and structured snippets. They make the ad larger and give searchers more reasons to choose you.

Step 7: Pick a bidding strategy that fits your data

• New account, few conversions: start with Maximise clicks with a maximum CPC, or Maximise conversions without a target, and a budget you are comfortable testing for a month.
• About 15–30 conversions a month per campaign: switch to Maximise conversions with a target CPA set around your actual cost per lead.
• Lead values known: use conversion values and target ROAS, so the algorithm prefers leads that are worth more.

Change one thing at a time and give each change two weeks before judging it. Smart Bidding needs time to relearn after every major change.

Step 8: Judge the right numbers every week

Clicks and click-through rate show whether ads are relevant; they don't show whether the account works. Each week, look at:

The most valuable habit is feeding outcomes back: mark which leads became customers, and if possible import those offline conversions into Google Ads. Then bidding optimises for customers, not form fills.

A launch checklist

• Lead conversion fires once, only on real success
• Calls and messaging clicks are tracked
• Consent Mode v2 and enhanced conversions are set up
• One campaign per main service, grouped by intent
• Phrase and exact match for core terms
• Negative keyword list in place before launch
• A matching, fast landing page for each campaign
• Ads with sitelinks, callouts and a pre-qualifying line
• Bidding strategy chosen for the amount of data you have
• Weekly review of search terms and cost per lead
